ubmucous fibrosis was first observed and described by Dr Joshi from India in 1953, in those patients who had the habit of chewing Pan Masala or Gutkha. Oral submucous fibrosis is a chronic disease. This condition also occurs within populations of Indians in South East Asian region. This condition may be rarely seen in the Western Countries, who have adopted their Indian dietary lifestyle and habits. The condition is probably genetically determined, as not all who chew Pan Masala will be affected. Patients who chew Pan Masala have tendency to develop submucous fibrosis. These patients first experience burning sensation and intolerance for spicy food or chillies. There are recurrent ulcers in the mouth, change in color of the oral lining and there is progressive development of tight feeling to open mouth leading on to inability to open mouth. The etiological factor is the Areca Nut (Supari), which is incorporated within Pan, Pan Masala and Gutkha. Initially, there is white appearance of the mucous membranes of inside cheeks which subsequently results in fibrosis below the epithelial surface. The tissues reveals that it is become rigid and the mouth opening is restricted. Palpation of the buccal mucosa and pterygomandibular raphe reveals that it is stiff and hard. There is staining of the teeth which signifies a concurrent tobacco chewing habit. This condition is highly premalignant. Biopsy of the mucosa is required in suspected premalignant lesions. It is essential that dietary habits involving chewing Pan Masala is stopped. The correction of any hematinic deficiency is also treated. Long-term follow-up is mandatory for the management. All cases involving premalignant lesions and conditions where follow-up is required because of biopsy proven dysplasia require careful record keeping following treatment and if further clinical deterioration should occur by and large, the ENT specialist and dentist will review these patients for life and will carefully observe for any untoward changes in oral mucous membrane.

From the desk of editor Patients are advised to stop chewing Pan Masala or Gutkha. Prevention is better than cure in submucous fibrosis. Once submucous fibrosis is established, antioxidant vitamins A, E, C and B6, Copper and Selenium are used. Mouth opening exercises along with repeated local steroids and hyalase injection may be helpful for trismus. When trismus is significant various surgical interventions are available. n

he most common cause of ear barotrauma is flying. Other causes are diving, decompression and hyperbaric oxygen chambers, and blast injuries. Barotrauma can manifest as ear pressure, pain and hearing loss, and tinnitus. Bleeding into the tympanic membrane may occur and rarely, rupture of the round or oval window membranes can cause vertigo and sensorineural hearing loss. Treatment Oral decongestants, antihistamines and nasal decongestant sprays used prior to flying or diving may reduce obstruction around the Eustachian tube and facilitate pressure equalization. Swallowing or the Valsalva maneuver can equalize pressures and prevent tissue injury. Chewing gum or sucking on hard candies can help adults Infants may be helped by nursing or sucking on a bottle. Special ear plugs may help equalize pressure for flying, but cannot be used for diving. Most barotrauma injuries heal spontaneously. Antibiotics are not indicated. Analgesics should be used as needed but glucocorticoids have not been shown to be effective. Dizziness (vertigo) and sensorineural hearing loss may indicate a perilymphatic fistula. Myringotomy has been used as both prevention and treatment for barotrauma related to flying. Ventilation tubes may be needed for someone undergoing hyperbaric oxygen therapy. Tympanoplasty or patching may be needed for serious injuries such as ossicular disruption or perilymphatic fistula.

Role of Corticosteroids in ENT Practice
Abstract Corticosteroids are increasingly being used to treat a wide range of otolaryngological disorders due to their anti-inflammatory action. They are effective in the management of idiopathic facial nerve palsy, allergic rhinitis, acute sinusitis, sinonasal inflammatory polyposis and laryngotracheobronchitis. Corticosteroids in ENT infections can be administered orally, intravenously, topically or by intralesional injection. The corticosteroids used in ENT practice may be short-acting like hydrocortisone, intermediate-acting like prednisolone, deflazacort and long-acting like dexamethasone and methylprednisolone. Steroid use is often based on anecdotal evidence or physician preference. There is a need to develop evidence based guidelines so that steroids can be safely used in ENT conditions. Key words: Anti-inflammatory, allergic rhinitis, idiopathic facial nerve palsy, acute sinusitis
orticosteroids are potent drugs with a wide range of application in various inflammatory and autoimmune disorders. Corticosteroids are increasingly being used in our daily clinical practice to treat a wide range of otolaryngological disorders due to their anti-inflammatory action. Treatment with corticosteroids has been shown to be effective in the management of idiopathic facial nerve palsy, allergic rhinitis, acute sinusitis, sinonasal inflammatory polyposis and laryngotracheobronchitis. Though corticosteroids have also been used in the management of Meniere’s disease, chronic otitis media and vestibular neuronitis with good results their therapeutic efficacy in these conditions still remains controversial. Mechanism of Action Corticosteroids have an anti-inflammatory effect at a subcellular level by activating glucocorticoid receptors, which interact with inflammatory transcription factors resulting in suppression of proinflammatory molecules like cytokines, prostaglandins and leukotrienes.1 At a cellular level, corticosteroids reduce the quantity of inflammatory cells like eosinophils, T lymphocytes, mast cells and dendritic cells. The degree of inflammatory suppression correlates with the tissue concentration of steroid.

Route of Administration The route of administration of corticosteroids in ENT infections varies from disease-to-disease. They can be administered orally, intravenously, topically or by intralesional injection. Since, intranasal topical corticosteroids undergo rapid first-pass hepatic metabolism, they cause minimal hypothalamicpituitary suppression and hence least side effects.2 Corticosteroids in the Armamentarium of an ENT Surgeon The corticosteroids used in ENT practice may be short-acting like hydrocortisone, intermediate-acting like prednisolone, deflazacort and long-acting like dexamethasone and methylprednisolone. Beclomethasone dipropionate, budesonide, fluticasone propionate, mometasone furoate and triamcinolone acetonide are some of the corticosteroids which are available for intranasal use. Diseases of the Ear Bell’s palsy
Bell’s palsy is a unilateral, peripheral facial paresis or paralysis that has an abrupt onset and no detectable cause. Bell palsy is one of the most common neurologic disorders affecting the cranial nerves, and it is certainly the most common cause of facial paralysis worldwide. Though the precise pathophysiology of Bell’s palsy remains an area of continuing debate, it
PHARMACOTHERAPY is thought that inflammation and swelling of the facial nerve results in compression of the nerve within the temporal bone. This has been seen in magnetic resonance imaging (MRI) scans with facial nerve enhancement.3
trial in patients with vestibular neuritis, it was demonstrated that daily administration of systemic methylprednisolone for three weeks significantly improved recovery of peripheral vestibular function as measured by electronystagmography (ENG).8
In Bell’s palsy, corticosteroids are frequently used either because of their possible immune modulating effect on the presumed viral etiology or because of reduction of neural edema within the facial canal due to their anti-inflammatory effect. Ramsey et al performed a meta-analysis of 27 prospective trials evaluating steroid therapy for Bell’s palsy in 2000. It was concluded that steroid therapy improved complete facial recovery by 17%, which was clinically and statistically significant.4 Further evidence to support steroid use was provided by Sullivan et al in 2007. In a double-blind, placebocontrolled, randomized trial involving around 500 patients with Bell’s palsy it was demonstrated that early use of prednisolone alone significantly increased the chances of complete facial nerve recovery at 3 and nine months.5
The effect of early steroid treatment on the evolution of IFP (idiopathic facial palsy) was evaluated in the Ear, Nose and Throat Service of the University Hospital of Alicante (Spain) with a prospective protocol from September 1991 to January 1992. The therapeutic protocol for all patients (47 patients) was an intramuscular injection of 60 mg prednisolone in the Emergency Room followed by a course of oral deflazacort that was gradually tapered-off. This Study found that clinical improvement was observed on day 149 and a complete cure by Day 3026. Full recovery of facial motor function without sequelae occurred in 95.6% of patients. These results support early steroid treatment for IFP.6 Vestibular Neuritis
Like Bell’s palsy, vestibular neuritis is presumed to have a viral etiology and has a high rate of spontaneous recovery. A retrospective study reviewed the role of steroids in the recovery of vestibular function in patients with vestibular neuritis. There was no correlation between steroid use and improvement in subjective symptoms, despite improved canal paresis recovery in the steroid group.7 However, in another prospective, double-blind, randomized controlled 10
Meniere’s disease is a disorder of the inner ear that can affect hearing and balance to a varying degree. It is characterized by episodes of vertigo and tinnitus and progressive hearing loss, usually in one ear. Both systemic and intratympanic steroids (ITS) are widely used empirically used in the management of Meniere’s disease. Support for their use has been demonstrated in a few studies. A prospective randomized double-blind study using five consecutive daily intratympanic dexamethasone 4 ug/ml injections for 22 patients with unilateral intractable Meniere’s disease reported 80% vertigo control after two years compared with 60% with placebo. They also reported subjective improvement in tinnitus (48% vs 20% placebo) and hearing loss (35% vs 10% placebo).9 Another prospective study which evaluated combined use of intratympanic and systemic dexamethasone in 17 patients with Meniere’s disease reported vertigo control in 76% but no significant improvement in hearing or tinnitus.10 Idiopathic Sudden Sensorineural Hearing Loss
Idiopathic sudden sensorineural hearing loss (SSHL) is a relatively common otologic disorder of uncertain etiology. Corticosteroids alone or in combination with other therapeutic modalities have been used for treatment of SSHL with mixed response. The addition of ITS to systemic steroid therapy did not confer any hearing recovery benefit in two recent studies.11,12 Multiple retrospective studies of salvage ITS therapy after failure of systemic steroids have reported improved hearing outcomes; however, the variability of study parameters makes comparison difficult and a well-designed prospective randomized trial is required to demonstrate the efficacy of ITS.13 Otitis Media with Effusion
Systemic and intranasal corticosteroids have also been used in the management of otitis media with effusion (OME). Oral steroids alone or in combination with Asian Journal of Ear, Nose & Throat, January-March 2011
PHARMACOTHERAPY an antibiotic have demonstrated faster resolution of OME in the short-term. Similarly, topical intranasal steroids combined with oral antibiotic also showed similar results in the short-term. However, there is not much evidence which supports use of oral or topical intranasal steroids for the long-term. Diseases of the Nose Allergic Rhinitis
Allergic rhinitis is clinically defined as a symptomatic disorder of the nose-induced by an IgE-mediated inflammation after allergen exposure of the membranes of the nose. It affects upto 25% of the general population. Symptoms of allergic rhinitis include rhinorrhea, nasal obstruction, nasal itching and sneezing which are reversible spontaneously or with treatment. Use of nasal corticosteroids has shown to be more useful than antihistamines in allergic rhinitis and currently it is the treatment of first choice. Usually 1-6 months of intranasal steroid treatment is required to obtain optimal results. Rhinosinusitis
In patients with acute rhinosinusitis, it has been shown that the use of intranasal corticosteroids in conjunction with oral antibiotics are more effective than antibiotics alone for achieving symptomatic improvement.14 Studies have also demonstrated that intranasal steroids alone are more effective than antibiotics in treating uncomplicated rhinosinusitis suggesting that monotherapy with intranasal steroids may be an effective treatment option for communityacquired uncomplicated acute sinusitis.15 Corticosteroids have found to be very effective in the management of chronic rhinosinusitis with nasal polyposis. A double-blind randomized controlled trial in patients with nasal polyps demonstrated the clinical efficacy of a short course of oral prednisolone.16 Another retrospective study demonstrated that a short course of oral prednisolone (1 mg/kg for 5 days) followed by daily intranasal beclomethasone was effective in 85% of patients with only 15% of patients requiring endoscopic sinus surgery.17 Oral steroids are now used preoperatively in patients undergoing endoscopic sinus surgery for nasal polyposis since they reduce vascularity and improve surgical nasal field conditions resulting in shorter operating time. Asian Journal of Ear, Nose & Throat, January-March 2011
Disease of Head and Neck Corticosteroids also have proven efficacy in a wide range of head and neck conditions. They are regularly used to reduce upper aerodigestive tract edema resulting from trauma, surgery, infections and anaphylaxis. Treatment of laryngotracheobronchitis with steroids is well-documented. Corticosteroid use as adjunctive therapy for other upper respiratory tract infections such as pharyngitis, epiglottitis and tonsillitis is common. Use of a single intravenous steroid dose (2-3 mg/kg methylprednisolone) in addition to antibiotic therapy and needle aspiration was compared with needle aspiration and antibiotics alone for the treatment of peritonsillar abscess. The steroid group had a statistically improved clinical outcome with no complications reported.18 Limitations of Corticosteroid Therapy While anti-inflammatory effects are inseparable from their metabolic effects, the goal of corticosteroid therapy is to obtain maximum clinical benefit with minimum adverse effects. Important adverse effects of long-term corticosteroid therapy include Cushingoid appearance, osteoporosis, cataracts, psychosis, dyspepsia and immunosuppression leading to serious infections. Children are more vulnerable to their side effects, particularly to effects on growth and adrenal suppression. It is therefore, important to balance steroid treatment benefits with the potential for side effects especially when using high-dose systemic therapy. Summary Corticosteroids play an important role in the management of a wide-spectrum of ENT problems faced by the clinicians in their day-to-day practice. However, steroid use is often based on anecdotal evidence or physician preference. There is a need to develop evidence-based guidelines so that steroids can be safely used in ENT conditions.

The Tongue-in-Groove Technique for Managing Nasal Tip Position U Raghavan
Abstract Despite advances in the knowledge of nasal anatomy and the ongoing development of new techniques, nasal tip modification remains a challenge. Many rhinoplasty maneuvers may result in loss of tip support. Despite the various techniques described in the literature, maintenance or improvement of nasal tip shape and position is difficult. The aim of this study was to assess the benefit of tongue-in-groove technique to maintain nasal tip projection. We examined 64 patients who had their nasal tip repositioned with a tongue-in-groove technique. The mean follow-up period was 21.1 months. The pre- and postoperative results of the nasal tip projection were measured manually using a ruler from the pre- and postoperative pictures. Among the patients studied 55% had their nasal tip projection increased by a mean of 1.4 mm and 33% had their nasal tip projection maintained at the preoperative level and 12.5% had reduction in nasal tip projection. Key words: Rhinoplasty, nasal tip, projection, tongue-in-groove
urgery of the nasal tip remains one of the most challenging aspects of esthetic nasal surgery.1-3 The main characteristics of the nasal tip can be described in terms of shape, rotation and projection.4 Mechanisms supporting the nasal tip have been welldescribed (Table 1).1 Rhinoplasty approaches violate most, if not all of them.4 Studies done 15 years ago showed that all rhinoplasty techniques without tip augmentation result in loss of tip projection.5,6 If this is to be avoided, nasal tip support structures must be re-established and reinforced.7 Over the decades many authors have described a variety of techniques to maintain and or enhance nasal tip projection, however, a consistently reliable technique has so far proved elusive. Historical Development of Tip Modification Techniques
vertical dome division type techniques.6,8-10 Cartilage tip grafts applied either as shields or as onlay grafts are strong instruments to increase nasal tip projection.11,12 Alternatively one may increase the length of medial crura by using a strut inserted in between the medial crura reaching upto but not resting on the nasal spine.13,14 Columellar struts give support to the medial crura but do not increase the nasal tip projection and hence they are often combined with tip grafts.11,15 If maximum support is needed for tip projection, a strut may be fixed on the nasal spine.16 Table 1. Tip Supporting Mechanisms1 Major Attachment of medial crural footplate to the caudal border of the septum Attachments of the alar cartilages to the upper lateral cartilages
Even in the time of Jacques-Joseph, it was known that most rhinoplasties resulted in loss of tip projection. He compensated for the loss of tip projection by lowering the dorsum. For decades excessive removal of the nasal dorsum to compensate for loss of tip projection resulted in undesirably small noses. Subsequently, techniques were developed to maintain and if necessary increase tip projection. This can be done by enhancing the height of middle crura by

Minor Anterior maxillary spine and soft tissue attachment of the medial crural feet Membranous septum Cartilaginous septal dorsum The ligamentous attachment between both lower lateral cartilages over the septal angle Sesamoid cartilages extending to the pyriform aperture
SuRgical Approach Different suture techniques attaching the medial crura to the septum directly or to a caudal septal extension graft have been described.17,18 Alternatively, Kridel and Foda suggested increasing the height of the medial crura by borrowing from the lateral crura called the lateral crural steal technique.19,20 This may be considered as an alternative to vertical dome division. Tongue-in-groove Technique
In recent years focus has shifted towards the medialcrura/septum complex to enhance nasal tip projection. The medial crurae may be long or short and may or may not overlap the caudal border of the septum. Long medial crura that overlap the septal cartilage provide the best tip support. The tongue-in-groove technique aims to mimic this anatomic situation in order to modify and control the position of the medial crura relative to the nasal septum.19,21,22 This involves sliding the two medial crurae on either side of the caudal border of the septal cartilage anteriorly or posteriorly and suturing them to the septum in order to achieve ideal nasal tip position (Fig. 1). If the septum is short a septal extension graft may be required to elongate the septum.23 This technique can thus alter the nasal tip projection and rotation and may also affect the position of the columella. A tongue-in-groove procedure can be considered as a variation of Tebbett’s techniques where sutures were used between medial crura and septum to change tip projection.15 Either the medial crura can be strengthened with a strut
and the whole complex fixed to the septum15 or the medial crura can be moved along the caudal border of the septum of septal extension graft and fixed.3,24 Rarely the length of the septum has to be shortened to correct the hanging columella effect. There are various ways to lengthen and strengthen the septum. A piece of cartilage can be fixed side-to-side or end to-end-to the caudal border of the septum making sure that it remains in mid line. Alternatively, spreader graft type extension grafts extending beyond the septum to which the caudal extension graft may be fixed adds further strength to the structure.3,25 Objective Measurement of Nasal Tip Projection Several methods have been described to measure nasal tip projection. Some of these methods such as those described by Baum, Simon and Powell and Humphrey’s are now mainly considered for their historical importance.26 Goode’s26 analysis states that the nasal tip projection is 0.55-0.6 of the length of the nasal dorsum, when the nasofacial angle is 360-400. Rich et al5 modified Crumley and Lanser26 technique to measure nasal tip projection and this was later used by Vuyk et al.4 Recently, Spörri et al used a computer program to measure nasal tip projection.27 The method was the same as described by Rich et al. In addition, computer software was used in the measuring process. Because the software used by Spoori et al was not available in our center, we measured the nasal tip projection using a ruler on the lateral view photograph. All pictures were taken from the same distance. The lateral view pictures were digitally cropped to show the area between the upper part of eyebrow and lowest point of chin. This standardized all pictures to take measurements with a ruler. In this study, we looked at the long-term tip projection that was achieved by using a tongue-in-groove technique. The ideal position of the nasal tip was determined preoperatively. Reducing, increasing or maintaining tip projection was done as indicated and position fixed in a tongue-in-groove manner.

This left a total of 64 patients which could be included in this study. All patients were operated on by the author. The decision whether to increase, maintain or decrease nasal tip projection and by how much were taken preoperatively based on the analysis of face of patient and photographs. Surgical Technique
All patients underwent an external rhinoplasty and their medial crurae were moved forwards or backwards so as to achieve the desired nasal tip position. The medial crurae were fixed to the caudal septum if the septal cartilage was long enough or otherwise to a cartilage septal extension graft fixed to the caudal border of the septum. Septal extensions were required in 35 patients (55%) as the caudal extension of septum was not sufficient for tongue-in-groove technique. The grafts were fixed to the septal cartilage side-to-side. By this method the nasal tips were fixed at an appropriate level without pulling the upper lip upwards. Evaluation Method
Manual measurements of the nasal tip projection were done using a ruler. The pre- and postoperative frontal and lateral view photos were taken at the same focal length. The lateral views were digitally cropped to include the area between the upper part of eyebrow to the lowest point of chin. These made the pre- and postoperative pictures of the same size so that they could be measured with a ruler to find the Goodeâ€™s ratio.
(Group 3) between 1 mm and 3 mm (mean 1.62 mm). All patients had the tip maintained at the preoperative level in Group 1 (Fig. 2). In Group 2, 32 patients had primary rhinoplasty and three patients had revision rhinoplasty. The preoperative decision was to increase the tip projection by 1 mm in 22 patients, by 2 mm in 10 patients and 3 mm in the three revision rhinoplasty patients (Fig. 3). Of these all the 22 patients who had the tip increased by 1 mm maintained it postoperatively in their subsequent follow-ups. Among the 10 patients where the tip was increased by 2 mm, eight patients (80%) maintained it and the rest two (20%) reduced the tip projection by 1 mm at the six months follow-up but maintained the tip projection at that level on further follow- up. All the three revision patients where the tip was increased by 3 mm lost the tip projection by 1.5 mm at the six months follow-up but maintained that projection at the 12 months follow-up and thereafter. In Group 3, all patients maintained the desired reduced tip projection (Fig. 4.) There were no postoperative complications (Table 2). Discussion The objective assessment in this study shows that 92% of the 64 patients, who had tongue-in-groove technique had their nasal tip projection increased or maintained postoperatively at the preoperatively decided level. This underscores the significance of the tongue-ingroove technique in modifying nasal tip position.
Results Sixty-four patients were studied, (there were 24 male and 40 female patients). Primary rhinoplasty was performed on 61 patients and three had revision rhinoplasty. Age ranged from 20 to 58 with a mean age of 34. The mean period of follow-up was 21.1 months (range 12-48 months). It was decided to maintain nasal tip projection at the preoperative level in 21 (33%) (Group 1) patients, increase in 35 patients (55%) (Group 2) by a mean of 1.48 mm (range 1-3 mm) and reduce the tip projection in the remaining eight patients (12.5%) Asian Journal of Ear, Nose & Throat, January-March 2011

Nasal tip projection decreased from the preoperatively decided level in 8% of the patients. Three of these patients had revision surgery done in other centers and had excessive scarring. Two patients who lost the tip projection by 1 mm had very thick sebaceous skin. It may be possible for the scar tissue contracture and contracture of the thick sebaceous skin to cause the loss of tip projection during the early healing period in these patients. There was a 50% loss of postoperative tip projection in all these five patients, and it may be necessary to take into consideration this and add more tip projection than is required to compensate for this loss in patients were there is possibility of more scar tissue contracture. This is similar to the surgeonsâ€™ 16
satisfaction rate of 97% reported by Kridel and Foda after studying 287 patients who had tongue-in-groove technique.20 Foda19 measured the outcome in a sample of 13 patients and found a statistically insignificant increase in tip projection. Byrd noticed improvement in nasal tip projection in 19 patients out of 20 studied. All studies including this one point to the efficacy of tongue-in-groove fixation to control of nasal tip projection (Table 3). The down side of this technique is the need for more cartilage if the septum needs lengthening. If the caudal extension graft is attached to the septum end-to-end then only a small graft is required, however, there is more chance of an unstable graft. Hence, we decided to use side-to-side attachment of caudal extension graft. In the tongue-in-groove technique the medial crura are separated and require precise reconstruction to avoid tip and columellar anomalies. The nasal tip may feel stiffer after this technique, however, none of our patients complained about this. When the tonguein-groove technique is used there is also the possibility Asian Journal of Ear, Nose & Throat, January-March 2011
SURGICAL APPROACH of increasing tip rotation more than when struts and tip grafts are used which should be kept in mind while fixing the medial crura. In this study all patients had open rhinoplasty even though it can be done using a closed rhinoplasty. It is possible to achieve better precision with this technique if an open approach is used. Techniques described to enhance nasal tip projection include columellar strut, nasal tip grafting, transdomal suturing and lateral crural steal.1 Columellar struts may change the position and shape of the columella.2 A previous study by Vuyk et al using ‘free-floating’ columellar struts to support nasal tip projection showed 60% of patients having increased or maintained nasal tip projection especially in the presence of a tip graft.4 The tongue-in-groove technique can be considered as an evolution from columellar struts by fixing them to caudal septum. Moreover, in the study by Vuyk et al, larger tip grafts were required to obtain optimum tip projection. Larger tip grafts have the risk of becoming visible through the skin over time.15 Byrd et al also agree that ‘free-floating’ columellar struts are incapable of providing sufficient support of the nasal tip.3 However, a recent study by Ingels et al has noted a slight increase in tip projection and rotation with columellar strut.28 This is similar to the observation by Vuyk et al4 that the columellar struts help in maintaining nasal tip projection. Conclusion The tongue-in-groove technique provides a reliable and reproducible method to recreate nasal tip support mechanisms. This also allows the tip to be repositioned to provide adequate nasal tip projection. The additional surgical maneuvers required are intricate but provide good tip support and a strong base for other techniques like suturing and tip grafting. If more tissue contracture is expected as in revision rhinoplasty and in patients with thick sebaceous skin it may be beneficial to increase tip projection more than required to compensate for the possible reduction. Even though there is a possibility for increased stiffness for the tip the predictability of tip position largely outweighs this risk. References 1. Tardy ME, Toriumi DM, Hecht DA.

Hashimoto’s Thyroiditis: Preoperative Diagnostic Challenge Sanjana V Nemade*, VV Rokade**, NA Pathak*, SD Deshmukh†, SM Sonar‡
Abstract Chronic (Hashimoto’s) thyroiditis is an autoimmune disease that may be associated with varying degrees of thyroid enlargement. The primary way to treat the disease is conservative; however, surgery has its place and efficacy in patients with pressure symptoms, pain and associated malignancy. In the selection of patients for surgical treatment, a discriminatory approach is necessary to prevent unnecessary surgeries. To achieve this, definite preoperative diagnosis of Hashimoto’s thyroiditis is the need. It may coexist with other common causes of thyromegaly like benign goiter or malignant thyroid disease. Thyroiditis can make thyroid dissection more difficult and possibly increase the risk of surgical complications like inadvertent parathyroidectomy, damage to recurrent laryngeal nerve. Our approach has been to establish reliable criteria for diagnosis of thyroiditis and indications for surgery. Hashimoto’s thyroiditis was diagnosed by clinical examination, fine-needle aspiration cytology (FNAC), antimicrosomal antibody, thyroid function studies, thyroid scan and the efficacy of all these criteria was assessed. Our experience with 87 cases of thyroid swelling operated at Smt. Kashibai Navale Medical College and General Hospital, Narhe, Pune from January 2007 to December 2009 was reviewed to determine the incidence of Hashimoto’s thyroiditis, reliable criteria for its diagnosis and the need of surgical intervention. Key words: Hashimoto’s thyroiditis, antimicrosomal antibody, thyroid scan, fine-needle aspiration cytology, serum TSH
hyroiditis is a group of inflammatory thyroid disorders. Patients with chronic lymphocytic thyroiditis (Hashimoto’s thyroiditis) present with hypothyroidism, goiter or both. The frequency of the disease appears to have increased during the past several decades.1 During the course of this disease, the cells of thyroid become insufficient in converting iodine into thyroid hormone and the gland ‘compensates’ by enlarging. A diffuse, firm goiter without signs of thyrotoxicosis, should suggest the diagnosis of Hashimoto’s thyroiditis. Most often the gland is bosselated or ‘rubbery’. It is usually symmetrical, although much variation in symmetry as well as consistency can occur. Pain and tenderness on deep palpation may be present.2

Hashimoto’s thyroiditis is considered an autoimmune disease with a variety of antithyroid antibodies whether detected in the patient’s serum. It is not established whether these antibodies are cytodestructive. Both humoral and cell-mediated immunity are probably involved in the production of this inflammatory response. Antimicrosomal antibodies (AMA) are directed against components of thyroid microsomes, in particular peroxidase. AMA are the most useful of all antithyroid antibodies and are present in 90-95% cases of Hashimoto’s thyroiditis.2-5 Thyroid uptake measurements and scintigraphic findings (usually obtained with technetium-99m [Tc-99m] or iodine-123) play an important role in the diagnosis of Hashimoto’s thyroiditis. The radioactive uptake shows heterogenous uptake, or may be paradoxically high as the gland retains its ability to ‘take up’ or ‘trap’ iodine even after it has lost its ability to produce thyroid hormone.6 Fine-needle aspiration cytology (FNAC) shows lymphocytes and macrophages in Hashimoto’s thyroiditis.7 In the initial stage of Hashimoto’s thyroiditis, patients are euthyroid. As the fibrosis advances, eventual reduction in thyroid function takes place. Thus hypothyroidism is a late manifestation of Hashimoto’s thyroiditis.2 Asian Journal of Ear, Nose & Throat, January-March 2011
CLINICAL PRACTICE Surgery is required in patients with Hashimoto’s thyroiditis in cases of pressure symptoms, persistent pain or if malignancy is suspected to be associated with it. Thyroiditis can make thyroid dissection more difficult due to fibrosis and possibly increase the risk of surgical complications like inadvertent parathyroidectomy leading to postoperative hypocalcemia, damage to recurrent laryngeal nerve.8-10 Preoperative diagnosis makes the surgeon aware of possible fibrosis and help him to take measures during surgery to prevent the possible complications. The present study was designed to assess the usefulness of diagnostic criteria for hashimoto’s thyroiditis. Our approach has been to establish diagnosis of thyroiditis by clinical characteristics, FNAC and thyroid function studies like elevated thyroid-stimulating hormone (TSH), positive thyroid antibodies and heterogenous uptake of radionuclide in thyroid scans. We studied the sensitivity and specificity of these criteria so as to establish a protocol for the necessary preoperative investigations in case of thyroid swelling to rule out Hashimoto’s thyroiditis. In the previous studies it has been observed that AMA is the most sensitive and specific investigation for Hashimoto’s thyroiditis.2,11,12 Thyroid hormonal profile and radioactive iodine uptake (RAIU) had been found to be helpful in assessing the functional status, but the information obtained from thyroid function tests is ‘soft’ as the secretion of TSH is influenced by many factors.12 The diagnostic accuracy of FNAC has been found to be high; however, multiple aspirations are required in almost all cases.7 Material and Methods Eighty-seven cases that underwent thyroidectomy at Smt. Kashibai Navale Medical College and General Hospital, Narhe, Pune from January 2007 to December 2009 were retrospectively studied. Data collected on each patient included: Age; sex; complaints of present illness; previous surgical history; family history of similar complaints; routine blood and urine analysis; serum calcium level; blood group; thyroid function tests: FT3, FT4, TSH; antimicrosomal antibody estimation; ultrasound of neck; scintigraphic scan of thyroid; FNAC of thyroid mass; computerized tomography in selected Asian Journal of Ear, Nose & Throat, January-March 2011
patients like those in the huge goiter, retrosternal extension or suspected malignancy. Histopathology reports were scrutinized for final diagnosis, presence of Hashimoto’s thyroiditis and the pathologic features of the gland. Diagnosis of Hashimoto’s thyroiditis was suspected on the basis of clinical and laboratory data, cytology, scintigraphy and was confirmed by histology of surgical specimens. We calculated the true-positive, true-negative, falsepositive and false-negative values for the investigations helpful in the diagnosis of Hashimoto’s thyroiditis i.e., antimicrosomal antibodies, FNAC, thyroid scan and serum TSH. Sensitivity and specificity calculator was applied to each parameter. We also studied the indication for surgery in patients with Hashimoto’s thyroiditis. Results Out of 87 patients who underwent thyroidectomy, 18 included Hashimoto’s thyroiditis with goiter, three had Hashimoto’s thyroiditis associated with papillary carcinoma, five had papillary carcinoma and 61 had benign goiter. The ratio of male-to-female was 2:85. All 21 patients of Hashimoto’s thyroiditis were females. Age range was 24-68 years (mean - 41.57). Fifty-nine patients underwent hemithyroidectomy, 22 patients underwent total thyroidectomy, four underwent subtotal thyroidectomy, two had completion thyroidectomy. Out of 21 patients of Hashimoto’s thyroiditis, 11 patients had diffuse, smooth firm rubbery swelling; eight patients had diffuse, nodular firm swelling and two patients had nodular, firm swelling with pain and tenderness on deep palpation. Antimicrosomal antibody was positive (>60 U/ml) in all 21 patients of Hashimoto’s thyroiditis. It was false-positive in three patients with no false negative (Table 1). Sensitivity of AMA was found to be 100% and specificity of 95.31%. Thus, AMA was found to be a highly sensitive and as well as a highly specific investigation in our study. FNAC was true-positive in six patients and no false positive. It was false-negative in 15 patients (Table 2). Sensitivity of FNAC was found to be 28.57% and specificity of 100%. Thus, FNAC was found to be highly specific but poorly sensitive for diagnosis of Hashimoto’s thyroiditis. Thyroid scan showed heterogenous uptake in 18 patients, and homogenous 19
Elevated TSH with normal T3 and T4 was found in two patients and euthyroidism in 19 patients (Table 4). Serum TSH was 14.29% sensitive and 100% specific for the diagnosis of Hashimoto’s thyroiditis. Indications for surgery in patients with Hashimoto’s thyroiditis were cosmetic disfigurement due to large goiter in 10 patients, pressure symptoms due to huge goiter in five patients, associated malignancy in three patients and persistent pain in three patients (Fig. 1).

Discussion The term ‘autoimmune thyroiditis’ encompasses multiple inflammatory conditions of the thyroid gland, each with variable clinical manifestations. The more acute forms, silent (painless) thyroiditis and postpartum thyroiditis, are associated with transient hyperthyroidism and are sometimes mistaken for Graves disease. The chronic form, Hashimoto thyroiditis (chronic autoimmune thyroiditis), results in goiter and eventual hypothyroidism unless it is recognized and treated promptly. Knowledge of the entire spectrum of these disorders is essential for appropriate case management.6 Asian Journal of Ear, Nose & Throat, January-March 2011
CLINICAL PRACTICE The most common type of thyroiditis - Hashimoto’s thyroiditis was first described by Hakaru Hashimoto, a Japanese surgeon working in Berlin, Germany. His report was based on the examination of four postoperative cases that he published in 1912. He is also credited with introducing the term struma lymphomatosa in reference to the syndrome. Its incidence in surgical specimens is relatively high, i.e., 13% in collected studies.1 This high incidence of thyroiditis in patients operated on to distinguish between benign and malignant thyroid disease seems to be based, primarily, on the inability to establish the diagnosis of Hashimoto’s thyroiditis before operation.1 Worldwide, the most common cause of hypothyroidism is iodine deficiency. However, Hashimoto’s thyroiditis remains the most common cause of spontaneous hypothyroidism in areas of adequate iodine intake. The incidence of Hashimoto’s thyroiditis is estimated to be 10-15 times higher in females.13 In our study all 21 patients with Hashimoto’s thyroiditis were females. The most commonly affected age range in Hashimoto’s thyroiditis is 30-50 years, with the peak incidence in men occurring 10-15 years later. The overall incidence of hypothyroidism increases with age in men and women.4 Hashimoto thyroiditis has a strong genetic component because there is a high prevalence of thyroid antibodies among first-degree relatives.2 In our study six patients gave significant family history in the form of similar complaints in family members. Commonest presentation of Hashimoto’s thyroiditis is euthyroidism and goiter, i.e. thyroid function studies are normal. Second common is subclinical hypothyroidism and goiter. In this, the autoimmune reaction results in lymphocytic and plasma cell infiltration with formation of lymphoid follicles, which in turn leads to thyroid follicle deterioration. A mild decline in circulating thyroid hormones is sensed by the pituitary gland, and a compensatory rise in TSH secretion stimulates the gland to synthesize more thyroid hormone so that T3 and T4 levels return to normal. Fibrosis develops over time. As a result of the ongoing replacement of the normal thyroid follicles by lymphocytes and fibrous tissue, there is eventual reduction in thyroid function because thyroid hormone production by the gland is impaired.2,10 Progression from subclinical hypothyroidism (normal FT4 but elevated TSH) to overt hypothyroidism occurs in a certain fraction Asian Journal of Ear, Nose & Throat, January-March 2011
(perhaps 3-5%) each year.2 Thus, hypothyroidism is the late manifestation of Hashimoto’s thyroiditis. In our study, out of 21 patients of Hashimoto’s thyroiditis, 2 patients had elevated TSH and normal T3, T4 (subclinical hypothyroidism). Nineteen patients were euthyroid with normal TSH at the time of presentation. Serum TSH is poorly sensitive (14.21%) but highly specific (100%) investigation for the diagnosis of Hashimoto’s thyroiditis. The goiter of Hashimoto’s thyroiditis may remain unchanged for decades but usually it gradually increases in size. Sudden increase in size may arise the suspicion of associated malignancy. Clinical findings are diffuse enlargement of the gland with or without lobulations. On palpation it has rubbery feel. Pain and tenderness on deep palpation may be there. Rarely, pain is persistent and unresponsive to medical treatment like steroids and requires surgery.2,8 In our study, firm rubbery feel on palpation was present in 11 patients of Hashimoto’s thyroiditis. Pain and tenderness on deep palpation was there in three patients of Hashimoto’s thyroiditis. Hashimoto’s thyroiditis is characterized by the destruction of thyroid cells by various cell- and antibody-mediated immune processes. The initiating process is not well-understood.3-5 Antibodies to various thyroid antigens, include AMA directed against components of thyroid microsomes, in particular peroxidase, antithyroglobulin (anti-Tg) and to a lesser extent, TSH receptor-blocking antibodies. Nevertheless, a small percentage of patients with Hashimoto’s thyroiditis (approximately 10-15%) may be antibody negative.9 AMA is the most useful of all antithyroid antibodies as they are often present in thyroid disease especially Hashimoto’s thyroiditis it is 95-99% positive when an assay of sufficient sensitivity is used. Anti-Tg antibodies are present in 55-90% of patients.2,4 AMA alone appears sufficient to detect autoimmune thyroid disease at about one-half the cost of routine of performing both AMA and anti-Tg studies. The widespread practice of performing both tests increases the cost without an offsetting diagnostic gain. AMA is much more sensitive than anti-Tg. AMA is positive in 99% of patients with Hashimoto’s thyroiditis. Mild-to-moderately elevated levels of thyroid antibodies may be found in a variety of thyroid and autoimmune disorders, 21
CLINICAL PRACTICE such as thyroid cancer, type 1 diabetes, rheumatoid arthritis, pernicious anemia and autoimmune collagen vascular diseases. Significantly increased concentration is considered significant and most frequently indicates thyroid autoimmune diseases such as Hashimoto’s thyroiditis or Graves’ disease.13 Young patients tend to have lower and occasionally negative levels. In this age group, even low titers signify the presence of thyroid autoimmunity.2 In our study, AMA was done by chemiluminescence immunoassay (CLIA). The value >60 U/ml was considered as positive. AMA was positive with values >150 U/ml in all 21 patients of Hashimoto’s thyroiditis. It was false positive in three patients out of which two had follicular adenoma and one had colloid goiter. Thus, AMA was found to be 100% sensitive as well as highly specific (95.31%) investigation for the diagnosis of Hashimoto’s thyroiditis. Scintigraphy (usually obtained with Tc-99m or iodine123) is useful in demonstrating the functional state of the thyroid at the time of clinical presentation and in differentiating autoimmune thyroiditis from other thyroid diseases, thereby influencing treatment.3 In Hashimoto’s thyroiditis, a mild decline in circulating thyroid hormones is sensed by the pituitary gland, and a compensatory rise in TSH secretion stimulates the gland to synthesize more thyroid hormone so that T3 and T4 levels return to normal. Thyroid follicles demonstrate a variable response to the chronic TSH stimulation, leading to patchy proliferation of these follicles. On a thyroid scan, this phenomenon manifests as areas of increased activity (follicles that respond to TSH) and of decreased activity (those that do not respond). This is shown as heterogenous uptake in thyroid scan. The image is characteristically that of a diffuse or mottled uptake in an enlarged gland, in striking contrast to the focal ‘cold’ and ‘hot’ areas of multinodular goiter. The uptake may be paradoxically high in few cases as thyroid follicles retain the ability to trap the iodine.2,6,7 Thus, heterogenous uptake of radionuclide should suspect Hashimoto’s thyroiditis. At our institution, the vast majority of thyroid scintigraphic scans are done with Tc-99m pertechnetate. Imaging was performed approximately 22
15 minutes after intravenous administration of 10 mCi of Tc-99m. In our study, 18 patients with Hashimoto’s thyroiditis showed heterogenous uptake in the scan and three patients showed cold nodule. Not a single false-positive was detected in our study. Thus, thyroid scan was found to be highly sensitive (85.71%) as well as highly specific (100%) investigation for the diagnosis of Hashimoto’s thyroiditis. Though, FNAC of thyroid provides a safe, simple and accurate method for diagnosis of thyroid disease, its diagnostic accuracy for Hashimoto’s thyroiditis is high only when multiple aspirations are used. The usefulness of increased number of aspirations has been stressed by Hamburger et al, who found that as the number of aspirations increase, false-negative results decrease.7 FNAC reveals lymphocytes, macrophages, scant colloid and a few epithelial cells which may show Hurthle cell change. In this study, FNAC was positive in six patients of hashimoto’s thyroiditis with no false-positive. Sensitivity of FNAC was found to be 28.57% and specificity was 100%. Thus, FNAC is highly specific but poorly sensitive for diagnosis of Hashimoto’s thyroiditis. The reason for poor sensitivity might be the single aspiration of the swelling in this study and further studies are warranted. Although chronic inflammation, leading to neoplastic transformation, is a well-established clinical phenomenon, the link between Hashimoto’s thyroiditis and thyroid cancer remains controversial. Elevated TSH results in a stimulus for growth and function of thyroid epithelium. TSH is a recognized promoting factor in thyroid cancer.1 The possibility that an immunologic mechanism involved in the pathogenesis of papillary carcinoma stimulates lymphocytic infiltration in the thyroid tissue through an autoimmune mechanism is suggested.9 In our study, three patients of Hashimoto’s thyroiditis had associated papillary carcinoma. Surgery has its place and efficacy in the treatment of selected patients with Hashimoto’s thyroiditis with compression symptoms, nodular forms with dominant nodules over 2 cm, suspicion for neoplasm, an unsightly neck appearance due to a large goiter or persistent pain.8,10 In this study, most of the patients of Hashimoto’s thyroiditis underwent surgery for pressure symptoms and unsightly neck appearance due to a large Asian Journal of Ear, Nose & Throat, January-March 2011
CLINICAL PRACTICE goiter (Fig. 1). Thyroiditis can make thyroid dissection more difficult and possibly increase the risk of surgical complications like mechanical damage, devascularization or inadvertent removal of the parathyroid glands, damage to recurrent laryngeal nerve.9 Inadvertent parathyroidectomy may lead to postoperative hypocalcemia and tetany. We believe in doing meticulous capsular dissection in loose areolar tissue around the thyroid gland. Identification of recurrent laryngeal nerve in Behr’s triangle and tracing it upto it’s entry in the larynx is important. We tried to identify and preserve the blood supply of parathyroids in all patients. Conclusion

Diagnosis of Hashimoto’s thyroiditis is suspected by the finding of a diffuse, smooth, firm to rubbery goiter in a young woman with euthyroid or hypothyroid metabolic status, and confirmed by high titers of AMA; heterogenous uptake of radionuclide in thyroid scan. These two are the most sensitive and specific investigations in the diagnosis of Hashimoto’s thyroiditis. FNAC is highly specific investigation but not as sensitive as AMA and thyroid scan.

Elevated TSH is also not found in significant number of patients. Thus, despite the availability of several tests for diagnosis of Hashimoto’s thyroiditis, AMA and thyroid scan remain the gold standard. When there is a dominant thyroid mass, we strongly believe in doing AMA and thyroid scan in every patient of thyroid swelling to rule out thyroiditis. Being a benign condition, accurate diagnosis reduces the rate of unnecessary operation, because hashimoto’s thyroiditis can be treated conservatively. If surgery is needed, availability of an experienced surgeon is important in order to avoid postoperative complications.

Relationship between Parent Perception of Hearing Loss in their Wards with Different Assessment Modalities in Children with Multiple Handicaps Noorain Alam*, Shamim Ansari**, Priyanka Mishra
Abstract Aim of the study: Children with multiple disabilities have combination of various disabilities. Accurate hearing evaluation is difficult in this population. Audiologists generally employ a test battery approach which includes combining findings of parent impression with behavior observation audiometry (BOA) as well as auditory brainstem response (ABR) findings. Present study was done to find if there was any correlation between various steps in test battery for the children with multiple handicaps as well as to find out which disability is the most common among this population. Methodology: Total 103 number of children with multiple handicaps were chosen at random who were referred to AYJNIHH, Mumbai for audiological assessment. The three steps involved in assessment, that is parental impression, BOA and ABR findings were taken into account. The relationship was obtained using data analysis. Results: It was found that among children with multiple handicaps referred for audiological assessment, mental retardation was the most common (32.03%). It was also found that there were more contradictory findings between parent impression and ABR (48%) when compared with parent impression with BOA (38%). In between BOA and ABR contradictory findings were found in 41% of cases. Conclusion: There are wide contradictions among various steps involved in assessment of children with multiple handicaps. Implication: Audiologist should use a test battery approach to assess hearing ability of this population and audiologists should interpret findings carefully at each level. Key words: Behavior observation audiometry, auditory brainstem response
hildren with multiple disabilities have a combination of various disabilities that may include: Speech, physical mobility, learning, mental retardation, visual, hearing, brain injury and possibly others. Along with multiple disabilities, they can also exhibit sensory losses and behavioural or social problems. Children with multiple disabilities - also referred to as multiple exceptionalities vary in severity and characteristics. The judgment made by the clinician on children’s hearing abilities often involves a differential evaluation. Accurate hearing evaluations are difficult in children with multiple disabilities. Approximately 25-33% of children with hearing loss have multiple potentially disabling conditions.1 This population requires modifications of diagnostic *Lecturer, Dept. of Audiology and Speech CU Shah Medical College, Gujarat **Lecturer, Dept. of Audiology Ali Yavar Jung National Institute for the Hearing Handicapped, Mumbai Address for correspondence Dr Noorain Alam Lecturer, Dept. of Audiology and Speech CU Shah Medical College Surendranagar, Gujarat E-mail: email@example.com
protocols as they are considered as ‘difficult to test’ population. Different steps involved in assessing the multiple handicapped children can be summarized as: Parental impression about the auditory status of the child Behavior observation audiometry/visual reinforcement audiometry (BOA/VRA) Brainstem evoked response audiometry (BERA) To come to a proper diagnosis the audiologist needs to correlate all the information obtained from each modality of tests given above. As parents observe children closely and are able to judge hearing status formally hence, their impression about the hearing is important. But in children with multiple handicaps they may relate lack of response to auditory stimuli to hearing loss which may be actually due to associated handicap. A skilled audiologist will decide the hearing status on BOA/VRA-based on subjective response of the client and this test shows poor testretest reliability, and high inter- and intrasubject variability (Bench, Collyer, Mentz, and Wilson, 1976; Weber, 1969; Wilson and Thompson, 1984).2 Asian Journal of Ear, Nose & Throat, January-March 2011
CLINICAL STUDY In auditory brainstem response (ABR), under good recording conditions, visual detection levels of wave V are usually within 10 dB of behavioral audiometric thresholds for click stimuli. Sometimes due to neuromaturational delay abnormal ABR recordings may be obtained. Whole test battery thus may show poor correlation among the different test modalities. A study conducted by Kitagawa Kae et al3 demonstrated coincidence between a secular change in ABER and the conditioned orientation reflex (COR) audiometry in 229 multiply handicapped children with motor disorders. Improvement in behavioral hearing testing minimum response level, including mental and physical development, was observed in 111 cases. There were 92 cases of ABR, and in 37 of them there was no correlation between the ABR and COR findings. The initial diagnosis in 44 patients was moderate-to-severe hearing loss, and a secular change was observed in 37 of them. The ABR thresholds and the COR minimum reaction level decreased in 11 patients, whereas in 17 patients ABR thresholds remained unchanged and only the COR values decreased. The final diagnosis was moderateto-severe hearing loss in 18 patients. The study shows the need of correlating different test modalities repeated over duration of time. Present study focused on the correlation of findings of different steps involved in the initial hearing assessment of children with multiple handicaps. Aim of the Study To provide evidence if three steps of the tests i.e., parent impression, BOA/VRA and ABR have a similar or contradictory findings. Methodology One-hundred three children with multiple handicaps less than three years of age, were selected and were referred to Ali Yavar Jung National Institute for the Hearing Handicapped, Mumbai for audiological assessment. The findings of all the steps involved in diagnosis of such population mainly parent impression, BOA/VRA and ABR were correlated. Descriptive data analysis was performed. Result and Discussion Findings indicate that among children with multiple handicaps who were referred for audiological assessment, MR is the most common Asian Journal of Ear, Nose & Throat, January-March 2011
disability (32.03%, when combined with Downs syndrome) while vision, heart and others (CLP and hernia) are the least (1.94% each) (Table 1 and Fig. 1). When parents’ impression is correlated with the findings on BOA and ABR we got following results: Parents suspected hearing loss: 56, Parents didn’t suspect hearing loss: 47, BOA confirmed hearing loss: 75, BOA rejected hearing loss: 28, ABR confirmed hearing loss: 56 and ABR rejected hearing loss: 47.
Findings on different tests showed following pattern: BOA vs ABR: Both of these tests have shown similar findings in 61 cases while they have contradictory findings in 42 (41%) cases out of which in 31 (73%) cases no hearing loss was demonstrated on ABR test while they failed BOA test.

Parent impression vs BOA: Both of these tests have shown similar findings in 64 cases but have contradictory findings in 39 (38%) cases out of which in 28 (71.8%) cases parent did not suspect hearing loss in their wards but BOA test failed them. Parent impression vs ABR: Both of these test have shown similar findings in 55 cases but have contradictory findings in 48 (46.6%) cases out of which in 24 (50%) cases parent did not suspect hearing loss in their wards but hearing loss was confirmed in them.
Conclusion The findings clearly show that in multiple handicap population there are more number of children with mental retardation and the various steps involved in audiological assessment of this population show wide contradiction.

Prognostic Value of Natural Antioxidant Enzymes Estimation in Treatment of Oral Submucous Fibrosis Bhavesh K Modi*, Ashish Katarkar**, Amit Tyagi†
Abstract Oral submucous fibrosis (OSMF) is quite common in the Indian subcontinent particularly in western India especially Gujarat. This study was designed to know the prognostic value of the natural antioxidant enzymes estimation before and after therapy. The result showed that estimation of natural antioxidant enzymes is important in guiding the clinician to decide the further line of management. Purpose: Study was designed to know the prognostic value of the natural antioxidant enzymes estimation before and after therapy. The study compared the pre- and post-therapy blood levels of antioxidant enzymes in patients with oral submucous fibrosis. Material and methods: In the present study, we selected 25 control cases (normal) aged above 12 years without any oral habit; oral symptoms and diseases were taken to find out the normal value of enzymes in blood of 50 tobacco-chewing subjects with frank OSMF with 1-2 finger mouth opening. The subjects having smoking habits were excluded from the study. Results: After one month of antioxidant supplementation therapy the levels were reversed i.e., SOD and CAT activity were increased and GSH and MDA levels were decreased in the tobacco chewers as compared to before treatment. Conclusion: Pre- and post-antioxidant supplementation therapy a marked variation in levels of glutathione was observed. In addition, it was noticed that the levels tended to shift closer to control/normal values post-antioxidant supplementation therapy. The value of glutathione and other enzymes estimated as a prognostic marker could be ratified if further studies are carried out on a larger scale over a sustained period of time. Key words: Oral submucous fibrosis, antioxidants, antioxidant enzymes
ral submucous fibrosis (OSMF) is a chronic insidious process characterized by fibrosis in the submucosal layers of oral cavity and pharynx. The condition was first described by Joshi in 1953.1 Prevalence of disease is 2-5 per 1,000 in the Indian subcontinent. OSMF causes changes not only in the submucous layer but also in the muscles. In the beginning it gives rise to symptoms like oral ulcers and later on there is progressively decreased mouth opening which has been confirmed by previous researches.2-4 Oxygen free radicals (OFR) give rise to this condition because of their potential toxicity to the cells. Due to their high reactive nature OFR can readily combine with other molecules such as enzymes, receptors and ion pumps causing oxidation directly *Ex-Associate Professor **Associate Professor, Dept. of ENT † Assistant Professor, Dept. of Biochemistry CU Shah Medical College, Gujarat Address for correspondence Dr Ashish Katarkar B-10, Doctor’s Quarters CU Shah Medical College Dudhrej Road, Surendranagar - 363 001, Gujarat E-mail: firstname.lastname@example.org; email@example.com

and inactivating or inhibiting their normal function. Various authors have suggested the roles of oxygen toxicity and antioxidant vitamins.5-7 Tobacco-chewing, smoking have been suggested as risk factors for the development of OSMF and carcinoma of oral cavity. Objective The study was to know the correlation between the estimation of enzymes in blood sample before and after antioxidant therapy and its clinical importance. Study was designed to know the prognostic value of the natural antioxidant enzymes estimation before and after therapy. The study compared the pre- and post-antioxidant therapy blood levels of antioxidant enzymes in patients with OSMF. Material and Methods The present study was conducted in Surendranagar district of Saurashtra region of Gujarat in India. Saurashtra region is an ideal for this study because of high prevalence of tobacco-chewing habit and high incidence of OSMF. Keeping the chewing tobacco in lower gingivolabial sulcus and chewing Gutkha is a common addiction in Gujarat. 27
CLINICAL STUDY Selection of Cases
Results and Discussion
Diagnosis of all cases of OSMF attending ENT OPD was done on clinical grounds for a period of 6-month and confirmed by a Consultant in the Department.
Human cells possess enzymatic antioxidant defence mechanism to cope with OFR e.g. SOD. In the present study there was overall decline (p < 0.001) in CAT and SOD activity and increase (p < 0.001) in GSH and MDA levels in tobacco chewers before treatment as compared to control (Figs. 1-4).
Methods of estimation used: GSH levels was measured by Beutler method,8 CAT activity was measured by Sinha method,9 SOD activity was measured by Mishra and Fridovich methods10 and plasma lipid peroxidation product i.e. MDA was quantified by Buege et al method.11 Clinical criteria for symptomatic evaluation of patients were as follows: Burning sensation in mouth Recurrent ulcer Decrease mouth opening Change in color of mucosa 28

Blood samples were collected in ethylenediaminetetraacetic acid (EDTA) bulb at zero day and after one month of antioxidant supplementation. Patients were advised to stop the tobacco in any form and started with antioxidant therapy.
All the selected cases underwent detailed history taking and thorough general physical examination, complete ENT examination and serum levels of superoxide dismutase (SOD), malondialdehyde (MDA), glutathione (GSH) and catalase (CAT) was done. Blood was collected from the antecubital vein.
Clinically the patients improved on following criteria after one month’s therapy.
For this study, we selected 25 control cases (normal) aged above 12 years without any oral habit; oral symptoms and diseases were taken to find out the normal value of enzymes in blood of 50 tobaccochewing subjects with frank OSMF with 1-2 finger mouth opening. The subjects having smoking habits were excluded from the study.
Clinical criteria for symptomatic evaluation of patients were as follows: Relief in the symptoms as told by the patients were assessed by the same observer on a scale of 0-10 where 0 is no improvement and 10 is 100% improvement in symptoms. All the patients were assessed clinically by the same observer on visual analog scale of 0-10.
All cases of OSMF (50) attending ENT OPD were studied. Cases with oral and/or oropharyngeal malignancy and patients having habit of smoking were excluded.

Burning sensation in mouth - more than 90% improvement Recurrent ulcer - 90% improvement Mouth opening - about 30% improvement Change in color of mucosa - about 40% improvement
After one month of antioxidant therapy supplementation the levels were reversed i.e., SOD and CAT activity were increased and GSH and MDA levels were decreased in the tobacco chewers as compared to before treatment. Antioxidant therapy included natural antioxidant enzymes and vitamins of synthetic agents in twice-daily dosage.12,13 Compositions of the antioxidant used are as follows.

Conclusion The present study revealed that antioxidant therapy14,15 along with estimation of antioxidant enzyme can give better results and can guide the clinician for further course of action. Also, this oral therapy can reduce the incidence of OSMF in longterm follow-up, rate of which is very high in the subcontinent thus reducing the treatment cost and morbidity and mortality. Post-antioxidant therapy we suggest further research and study on a large population and do enzyme estimation at 3-month and one year - for considering it an evidence-based treatment for submucous fibrosis.

Primary Tuberculosis of the Temporomandibular Joint: A Diagnostic Dilemma Piyush*, Manisha Pal**, Achal Gulati†, Ishwar Singh†
Abstract Primary tuberculosis of the temporomandibular (TM) joint is symptomless in majority of individuals. The clinical picture of tuberculosis usually mimics the ordinary arthritis of the joint or as a parotid swelling, thus causing difficulty in reaching the appropriate diagnosis. Key words: Temporomandibular joint, tuberculosis of the joint
uberculosis is a very common disease in India and its incidence is rapidly rising in the other parts of the world also, especially after AIDS. Primary tuberculosis usually infects the lungs with secondary infection of other organs and tissues. Tuberculosis of the facial bones has been reported occasionally but tuberculosis of the temporomandibular (TM) joint is rarely seen. Tuberculosis of this joint should always be considered in the differential diagnosis in patients suffering from pain and stiffness of the TM joint1 or if the patient presents with parotid a swelling accompanied by joint pain and stiffness. Case Report A 16-year-old female presented to our outpatient clinic with the complaints of a swelling in the left preauricular region for the past one month. The swelling was of the size of a pea to start with but gradually increased to the present size (Fig. 1). The swelling was associated with fever and mild pain with slight difficulty in opening the mouth. Patient had no other complaints and no significant past or family history. Her general physical examination was normal and on local examination there was a swelling in the left preauricular swelling measuring about 2.5 cm by 2.5 cm; the swelling was nontender to touch, was tense and cystic in consistency and was mildly fluctuant. The temperature over the swelling was not raised. There was slight restriction in opening the mouth. Per oral examination was within normal limits.

case report provisional diagnosis of parotid abscess was considered. The patient was prescribed oral antibiotics and NSAIDs and was sent for fine-needle aspiration cytology. CT scan was advised to find the extent of the swelling and to rule out any other pathology like parotid cysts. Fine-needle cytology showed tuberculosis and on CT scan it was found that the swelling was not of the parotid but an abscess involving the TM joint. There was no destruction of the joint (Fig. 2). Chest X-ray was normal, Mantoux was positive and ESR was also raised. Patient was advised a full course of antitubercular therapy; antigravity aspiration of the abscess was undertaken and physiotherapy of the TM joint was advised. Patient improved symptomatically and now after the completion of the course she has no complaints of the TM joint. Discussion The prevalence of tuberculosis of the bones and the joints has been on the rise and this increase is usually related to the AIDS disease. Extrapulmonary tuberculosis is a diagnostic challenge for the clinicians, especially in the absence of any pulmonary signs and symptoms. Usually the tuberculosis of the TM joint is misdiagnosed as an ordinary arthritis, and if there is a parotid swelling it is usually misdiagnosed as a parotid pathology ignoring the underlying joint pathology. Thus tuberculosis of the TM joint is a diagnostic dilemma and poses a diagnostic challenge.2 The TM joint may be affected from tuberculosis in the adjacent mandibular body or rarely by hematogenous route. The two factors cited for the rarity of the tuberculosis of the TM joint are as follows:3 High local immunity of the oral mucosa The predilection of tubercle bacilli for the cancellous bone. When tuberculosis presents as a lesion in the TM joint the correct diagnosis is of essence to start the appropriate treatment. The diagnosis of the joint tuberculosis in the developing countries is made on the basis of clinical and radiological examination.4
It is possible that the low frequency of the tuberculosis of the TM joint reported may be due to misdiagnosis, thus one should always keep a differential diagnosis when such a situation is presented in the clinics. Conclusion Tuberculosis of the TM joint is a very rare disease and has been reported very infrequently in literature of all surgical disciplines. Radiology is important in the diagnosis and the differentiation of this entity from the parotid swelling as well as from the ordinary arthritis of the TM joint, thus helping in instituting the appropriate management. Antitubercular therapy, aspiration drainage of cold abscess and physiotherapy helps in treating the disease. Open surgery may be reserved for cases not responding the above treatment. If the disease is left untreated it will cause fibrous ankylosis while a discharging abscess can lead on to infection and destruction of the joint and bony ankylosis.5,6 A corrective osteotomy may be required for bony ankylosis.7 References 1.

Use of Temporalis Myofascial Flap for Interpositional Arthroplasty in Temporomandibular Joint Ankylosis Amarjeet Gambhir*, Gita Rani**
Abstract Ankylosis of the temporomandibular joint (TMJ) is one of the most exasperating handicaps, a human being can suffer from. A variety of materials such as dermal grafts, auricular cartilage, costochondral graft and fascia lata have been used as TMJ disk replacement after surgery. The temporalis muscle and fascia flap has previously been used to support and replace orbital contents, and to reconstruct the oral cavity and maxillofacial region following ablative surgery. This article describes the successful application of temporalis muscle and fascia flap for interpositioning arthroplasty following release of TMJ ankylosis. Key words: Ankylosis, graft, arthroplasty, recurrence
nkylosis is a Greek terminology meaning ‘stiff joint’. Ankylosis of the temporomandibular joint (TMJ) is a serious and disabling condition because it not only compromises joint function, but if acquired at an early age results in severe cosmetic deformity, affecting the individual’s psyche and self esteem. Left untreated, it can lead to distressing sequelae such as compromised facial growth and development, impaired speech and nutrition, respiratory distress, malocclusion and so on. TMJ ankylosis is classified by location (intra-articular or extra-articular), type of tissue involved (bone, fibrous or fibro-osseous), and extent of fusion (complete or incomplete).1 Trauma, infection, radiotherapy, surgical excision of TMJ tumors and systemic disease can all result in mandibular hypomobility.2 Though over the years, the technique for releasing TMJ ankylosis seems to have been standardized, high recurrence rate is a persistent problem bothering patients as well as surgeons. The exact cause of recurrence is difficult to pinpoint. It has been attributed to factors such as:

Bone regeneration Inadequate postoperative physiotherapy Incomplete resection Nonavailability of satisfactory interpositional material
Plethora of interpositioning materials have been used with variable amount of success, yet successful rehabilitation of patients with ankylosis continues to be a challenge for surgeons. This article describes the successful use of temporalis myofascial flap as an interpositioning material for TMJ ankylosis. Case Report A 10-year-old male child reported to maxillofacial OPD of Nair Hospital Dental College, Mumbai with the chief complaint of restricted mouth opening and difficulty in eating and speech since five years. Patient gave history of trauma to chin due to fall at the age of five years. However, no treatment was taken for the same. Oral opening reduced gradually over the next few years to the present value. His past medical history, family and personal history was noncontributory. Patient was thoroughly evaluated systemically and clinically. Extraoral examination revealed an obvious facial asymmetry with deviation of chin towards the left side of face (Fig. 1). There was flattening of face on right side and fullness on left side with retruded mandible and chin and an accentuated left antegonial notch. Right TMJ movements were palpable in all excursions, while left Asian Journal of Ear, Nose & Throat, January-March 2011

side movements were palpable but reduced (Fig. 2). Intraoral examination revealed an interincisal opening of 2 cm with deviation of mandible to left side and a fair oral hygiene (Fig. 3). Radiographic examination in the form of OPG and CT scan revealed fusion of the left condyle with glenoid fossa and elongation of both coronoid processes (Fig. 4 and 5). Asian Journal of Ear, Nose & Throat, January-March 2011
Following blind awake intubation, ankylosed mass on left side was exposed using Al-Kayat and Bramleyâ€™s modified preauricular incision (Fig. 6).3 Coronoidectomy was done using surgical bur and bone removal continued inferiorly to create a gap of approximately 1 cm (Fig. 7). Jaw stretcher was applied and an interincisal opening of 4.5 cm was obtained. Temporalis myofascial flap was then created, rotated under the zygomatic arch and anchored to the capsular remnants medially with 30 vicryl sutures (Fig. 8). Since, adequate oral opening could be achieved, contralateral coronoidectomy was deferred. Closure of wound was done in layers with 3-0 vicryl and 3-0 silk for dermal closure (Fig. 9). 33

Discussion At our institute, we have been privileged to follow-up a large number of cases of TMJ ankylosis treated by adaptation of Kabanâ€™s protocol4 as well as using various other interpositioning materials on long-term basis. It can be concluded that no single method has produced uniform results.

Jaw physiotherapy was started from the first postoperative day (Figs. 10 and 11). Postoperative wound healing was satisfactory and sutures were removed on 10th day. There was no evidence of facial nerve injury. Patient maintained oral opening of 4.4 cm at follow-up visit after 1-year. 34
Interpositional arthroplasty has become the mainstay of treatment nowadays as it possibly reduces recurrence and also maintains ramus height to certain extent.5 Till date, a variety of interpositioning materials ranging from autogenous to alloplastic have been used with variable success rate. Alloplastic materials have fallen into disfavor due to long-term complications like foreign body reaction, condylar resorption and malocclusion. Autogenous materials are the first choice. Costochondral graft is good in maintaining the ramus height and can partially Asian Journal of Ear, Nose & Throat, January-March 2011
case report replace the condylar growth center. But nowadays, its use is decreasing due to disadvantages like increased operating time, additional surgical site and donor site morbidity such as pneumothorax and pleuritic pain. Moreover, its growth pattern is quite unpredictable, increasing the possibility of re-ankylosis and the need for secondary corrective osteotomies.6 Temporalis muscle and/or fascia flap has given consistently good results when used as an interpositioning material following ankylosis release. It has the advantage that its arc of rotation can be altered by basing the flap inferiorly or posteriorly. Additionally, its dependable blood supply and proximity to TMJ make it a versatile flap for lining the glenoid fossa.7 The muscle and fascia are of adequate thickness, and the long-term viability of the flap has been demonstrated.8 Conclusion It can be concluded that the temporalis fascial flap satisfies most of the requirements of an ideal interpositioning material following ankylosis release. Its excellent blood supply, versatility and minimal donor site morbidity are the primary advantages.

An Unusual and Rare Case Report of External Auditory Canal Cholesteatoma Nishi Gupta*, Nidhi Dhawan*, Alok Kumar*, Parul Mathur*
Abstract External auditory canal cholesteatoma (EACC) is an extremely rare otologic disorder being seen in one out of a thousand ear patients. The pathogenesis of this rare disorder is still an enigma. Usually thought to be a geriatric disorder, we present here a case of a middle-aged woman with EACC. This case was unusual in several ways and was finally confirmed on histopathological examination. Our patient had a short history of hearing loss without ear discharge. Usual presentation of this nature is commoner in keratosis obturans where there is pain and hearing loss without otorrhea. Key words: External auditory canal cholesteatoma, keratosis obturans, treatment options
Case History In this case a 35-year-old woman presented to our OPD with complaint of hearing loss and pain in the right ear of 1-month duration. She had no history of ear discharge. This was her first episode of an ear disorder with no pre-existing ear disease. Her clinical examination revealed that the ear was full of wax and the external auditory canal (EAC) was obscured. The canal stenosis had been gradual and progressive. There were no significant findings in the nose or the throat. The hearing loss was of pure conductive nature. No cranial nerve abnormality was elicitable.
Figure 1. Soft tissue mass with flakes and debris.
The patient was taken up for clearance of the EAC and examination under microscope. Her intraoperative findings showed a bony stenosis that had to be drilled out. As the stenotic segment was cleared, a soft tissue mass was detected with flakes and debris (Fig. 1). The mass was excised en sac and sent for histopathologic examination. The tympanic membrane was found to be normal. Tympanotomy revealed that the ossicles were intact and mobile. The biopsy report was consistent with cholesteatoma for the excised soft tissue mass (Fig. 2). The bone specimen revealed necrosis without inflammatory reaction. Discussion External auditory canal cholesteatoma (EACC) is an extremely rare condition of the ear with an incidence *Dr Shroffâ€™s Charity Eye Hospital Daryaganj, Delhi - 110 002

of less than 1 in 1,000 ear patients. It is usually a condition of the elderly and thought to be due to loss of lateral epithelial migration. Usually a chronic disorder, it is associated with otorrhea and a soft tissue mass in the EAC. Bony erosion of the EAC is the norm. Asian Journal of Ear, Nose & Throat, January-March 2011
case report The pathogenesis of this rare disorder is still an enigma. It is proposed that poor blood supply may contribute to it in the elderly as well as the loss of epithelial migration outwards. The self-cleansing nature of the EAC being lost, the external canal gets filled with keratin debris and a soft tissue locally erosive mass that causes widening of the external canal. Previously thought to be variants of the same disorder, EACC and keratosis obturans (KO) are now considered to be different disease entities by several scholars. Of significance is the fact that KO is usually bilateral and acute in presentation, is usually associated with pain. KO presents with painful loss of hearing with rarely a history of associated ear discharge. This is a condition of younger age group. On the other hand, EACC is a disease of geriatric age group, usually indolent and chronic in nature and is marked by ear discharge. It is associated with hearing loss and rarely presents with pain. It is unusual that our patient had acute presentation, no ear discharge, was a young patient and the histology was consistent with cholesteatoma. The clinical features clearly and unequivocally suggested KO while, histology confirmed EACC. It is proposed that the distinction between the two entities be merged and the treatment be dictated by clinical picture rather than by nomenclatured diagnosis.

From eMedinews What Happens if Allergy of Nose is not Treated? Nasal allergy leads to localized edema of the mucosa, which can block the opening of the sinus osteum thus leading to retained secretions in the sinuses which get secondarily infected thus causing sinusitis. Some cases of allergic rhinitis may progress to develop allergic nasal polyposis. Rhinitis and asthma are also closely linked i.e. about 75% of asthmatics have associated rhinitis. Patients of rhinitis who are asymptomatic for asthma have some inflammation of lower airway which can later on develop into asthma. Treatment of allergic rhinitis reduces the risk of asthma and lowers the dose of medication required to treat asthma. What is the Treatment for Persistent Watering of the Eyes and What is the Role of ENT Surgeon in this? Lacrimal pathway from the eyes drains into the nose. Epiphora or watering of the eyes can be due to blockage of lacrimal pathway thus not allowing outflow of tears from the eyes to nose. The blockage can present clinically as epiphora or repeated infection and swelling at the medial canthus of the eye. When the blockage is at the level of the lacrimal sac or nasolacrimal duct, dacryocystorhinostomy is done i.e. an opening of the lacrimal sac into the nose is made. Since, most of the pathway is anatomically-related to the nose, the surgery can very easily be done through nose by nasal endoscopic surgeon. The nasal endoscopic approach is a good alternative to the external approach as the results are better, there is no external scar and associated nasal pathology like deviated septum or sinusitis can be corrected in the same sitting. —Dr Aru Handa MS, DNB (Dept. Co-ordinator and Senior Consultant Dept. of ENT Moolchand Medcity)
