Chronic suppurative otitis media is one of the common otological conditions in India for which patients seek advice from an otorhinolaryngologist. Chronic suppurative otitis media is recurrent and progressive disease which is characterized with tympanic membrane perforation and suppurative discharge. Pure tone audiometry is the most common test used to evaluate auditory sensitivity. Since hearing loss is a common complication of chronic suppurative otitis media, we designed this study to evaluate preoperative pure tone audiometry findings in patients with chronic suppurative otitis media and its correlation with the intra-operative findings. <strong>Aims and Objectives:</strong> 1] To assess the intra-operative findings in patients with chronic suppurative otitis media. 2] To evaluate the correlation between the preoperative pure tone audiometry findings and intra-operative findings in patients with chronic suppurative otitis media. 3] To assess the type of hearing loss and degree of hearing loss in patients with chronic suppurative otitis media. <strong>Materials and Methods:</strong> This is an Observational study carried over a period of 3 years from August 2011 to August 2013. Total number of patients included in this study was 100. <strong>Result:</strong> Out of 100 patients studied 69 % of patients had Tubo-Tympanic type of CSOM, 31 % of patients had Attico-antral type of CSOM. In patients of Safe CSOM; Central perforation was seen in maximum cases 46.4 %, anterior central perforations was seen in 8.7 % cases, posterior central perforations seen in 20.2 % cases, and subtotal perforations seen in 24.63 % cases. In patients of Unsafe CSOM posterosuperior cholesteatoma was seen in maximum cases 67.74 %, and attic cholesteatoma was seen in 32.2 % cases. In safe CSOM patients all ossicles were intact and mobile whereas in unsafe CSOM patients only 4 patients had intact ossicular chain, while maximum patients had ossicular defect. <strong>Conclusion:</strong> Hearing loss depends on size of perforation. Hearing loss increases as the size of perforation increases. Average air conduction threshold and air bone gap did not differ significantly between various groups of ossicular defect. This shows us that neither air conduction nor air bone gap are reliable parameters on basis of which we can predict ossicular status preoperatively.

Hearing loss was significantly more in posterior perforation (46.61±7.02 dBHL) than in anterior perforation of TM (32.65±8.77 dBHL).<strong> </strong>There was a statistically significant difference in pure tone average hearing loss between intact ossicle group (32.87±9.77 dBHL)<strong> </strong>and eroded ossicle group (43.39±9.60dBHL). Difference in air bone gap was also significant between intact ossicle group (24.09±9.56 dB) and eroded ossicle group (31.02±9.83 dB). Multiple ossicles were eroded in nineteen patients with incus being the most commonly eroded ossicle.</p><p><strong>Conclusions:</strong> In this study, hearing loss increased with increased size of TM perforation and also with posterior perforation. Incus was found to be the most commonly eroded ossicle. Multiple ossicles were seen eroded most commonly when hearing loss was moderate. The surgeon will be better equipped to do ossiculoplasty in view of these preoperative findings and also to counsel the patient better about their expectation of hearing improvement following surgery. </p>

<p><strong>Background:</strong> Chronic suppurative otitis media (CSOM) has been an important cause of hearing loss and ear discharge in people affected by it for a significant time now. Its prevalence is more in developing countries where the socioeconomic status is low. Poor and overcrowded living conditions, poor hygiene and nutrition have been suggested as a basis for the widespread prevalence of CSOM in developing countries. Pure tone audiometry is the easiest and the most basic procedure which needs to be performed on any patient who has history of hearing loss irrespective of the nature of the disease and the cause surrounding it. Every initial evaluation for CSOM should include audiometric testing via air and bone along with pure tone thresholds. Aim of the study was to co-relate the hearing loss to the duration of the disease in the ear in patients with CSOM and to also associate the same to the corresponding hearing changes after myringoplasty.</p><p><strong>Methods: </strong>Sixty patients were taken to be part of the study after following a strict inclusion and exclusion criteria. With proper consent, they underwent pure tone audiogram and myringoplasty. Their air bone (AC) gap and air conduction (AC) threshold results were tabulated with the duration of the disease and a consensus was reached at.</p><p><strong>Results: </strong>It was observed that the hearing loss was much lesser if the duration of the disease was lesser than one year.  As the diagnosis was delayed, both the AB gap and mean AC threshold went up. The early closure of the perforation can significantly bridge the AB gap but the same cannot be said about the AC threshold as it seemed to be lesser affected by the duration.</p><p><strong>Conclusions: </strong>It can thus be concluded that AC threshold is quietly independent of the changes in the diseased middle ear as compared to the AB gap. This makes it a stronger tool in the assessment of hearing. The early diagnosis and management of tubotympanic type of CSOM can not only help in preventing complications but also aid in better hearing protection which in-turn helps in better social survival.</p>

Myringoplasty is one of the most common ear surgery performed for chronic suppurative otitis media tubo tympanic type. The prime concern for patients who are willing to undergo myringoplasty is hearing improvement. The aim of this study is to assess the improvement of hearing after myringoplasties for Chronic Suppurative Otitis Media tubo tympanic type. The total number of patients included in the study was 105. Myringoplasties were performed in 129 patients, and only those who had graft uptake i.e. 105, were selected for the study. Age of the patients varied from 13 to 45 years. Pure tone audiogram was done before the operation and four weeks after the operation, and air conduction thresholds were compared. It was found that 83% of the patients had some degree of hearing improvement after the operation. No significant complications were observed except that few patients complained of pain at the site of incision for harvesting the graft. Thus, this study shows that, patients can be assured that the chances of hearing improvement is acceptable and can undergo the operation without fearing complications.

Suppurative Otitis Media

Background: Pure tone audiometry is routinely used to determine conductive and sensorineural hearing status. Ossicular discontinuity is usually assessed intra-operatively. If ossicular discontinuity can be predicted by pure tone audiometry, perhaps the operative procedure of choice and prognosis for hearing can also be anticipated.   Objective: To determine the predictive value of preoperative pure tone audiometry on the presence of gross ossicular discontinuity in chronic otitis media.   Methods: Records of 205 patients, 7 to 75 years of age undergoing their first operation for chronic otitis media were reviewed. Preoperative audiograms and operative records for tympanomastoidectomy were evaluated. A total of 162 patients meeting inclusion criteria were included in the study. Likelihood ratios for positive and negative ossicular discontinuity for frequency-specific air-bone gap cut-offs were determined. Multiple logistic regression analysis for pure tone audiometry and operative findings to predict ossicular discontinuity was performed and a model for predicting ossicular discontinuity using logistic regression obtained.   Results and Conclusion: Frequency-specific air bone gap (ABG) cut-off values can predict ossicular discontinuity in chronic suppurative otitis media namely: < 20 dB ABG at 500 Hz predicts absence of ossicular discontinuity while > 50 dB ABG at 500 Hz, >30 dB ABG at 2 KHz, and > 50 dB ABG at 4 KHz best predict the presence of ossicular discontinuity in general. In the absence of cholesteatoma, the air bone gaps of <30 dB at 500 Hz and <20 dB at 1 KHz decrease probability of ossicular discontinuity from 32.97% to 2.54%. Combination of air bone gaps of >50 dB at 500 Hz, >20 dB at 2 KHz and >40 dB at 4 KHz increase the probability of ossicular discontinuity from 32.97% to 85.9%. These findings suggest that ossicular exploration may not be necessary for the former while an evaluation of the ossicular chain may be mandatory for the latter in the setting where cholesteatoma is not present or suspected.             Presence of cholesteatoma, granulation tissue and size of tympanic membrane perforation are important factors to consider in predicting ossicular discontinuity.   Keywords: air bone gap; audiometry, pure tone; ossicular discontinuity; otitis media, suppurative; logistic reg

Introduction             Chronic otitis media (COM) is a most common and prevalent disease of the middle ear. COM has been defined as a longstanding inflammatory condition of middle ear and mastoid, associated with perforation of the tympanic membrane. Tympanoplasties are common surgeries performed for chronic otitis media in inactive mucosal type. Any otological surgery may involve a menace/ hazard of hearing loss post operatively.             In this study, an attempt was made to correlate, size of tympanic membrane perforation, pure tone audiometry and intra-operative findings in tympanoplasties, results were analysed and conclusion drawn. Materials and Methods Forty patients attending ENT OPD with chronic otitis media (COM), inactive mucosal type, with conductive hearing loss undergoing tympanoplasties who were willing to participate in the study were selected.  Ear was examined pre-operatively to assess the size of perforation and then, pure tone audiometry (PTA) was done to assess the type of hearing loss and its severity. During tympanoplasty, middle ear was inspected for ossicular status and any other pathology was noted. Later, the size of tympanic membrane perforation, pure tone audiometry and intra operative findings were correlated with each other and analysed. Result  In small and medium sized perforation, PTA and intraoperative findings correlated with each other. Whereas, in large and subtotal perforation, there was no correlation. Conclusion             In small and medium sized perforation, middle ear inspection may not be necessary. Whereas, in large and subtotal perforation it is necessary.

AbstractThe aim of the study was to review the literature of tympanoscierosis especially its pathogenesis, to study the general incidence of tympanoscierosis among patients with chronic suppurative otitis media (CSOM), its association with cholesteatoma and also the type of hearing loss as well as its relation to the degree and site of tympanosclerosis.Seven hundred and seventy-five patients with CSOM were studied retrospectively. A full history was taken and thorough ENT examinations were carried out. Pure tone audiograms (PTA) of all patients were done and analysed. The operative finding of tympanosclerosis as well as middle-ear status were inspected.The incidence of tympanosclerosis was found to be 11.6 per cent (90 patients out of 775 CSOM cases). Most tympanosclerosis cases had dry ear, (85.6 per cent). Of the 57.8 per cent who had myringosclerosis, their PTA showed an AB gap 20–40 dB. When sclerosis affect both the tympanic membrane and middle ear, 61 per cent of patients had an AB gap >40 dB. The association of cholesteatoma and tympanosclerosis may be regarded as uncommon, 2.2 per cent.The exact aetiology and pathogenesis of tympanosclerosis is as yet not well known. Our study concentrated on the clinical picture of tympanosclerosis among patients with CSOM. The majority of hearing loss associated with tympanosclerosis was of the conductive type.

Objective: The main objective of this study is to assess the intraoperative finding during canal wall down mastoidectomy in paediatric patients undergoing surgery for unsafe type of chronic suppurative otitis media (CSOM) attending ENT OPD of Kathmandu Medical College. Materials and Methods: Fifty patients of age group 4 to 13 years who were suffering from unsafe type of CSOM with or without cholesteatoma were taken for the study. The study period was two years from April 2007 to March 2009. The operative findings like extent of cholesteatoma in different location of middle ear cleft, mastoid bony landmarks, and ossicular chain condition and otogenic complication were identified during canal wall down mastoidectomy. Result: Of the 50 patients 32 (64%) were boys and 18(36%) were girls. The age ranged from 4 years to 13 years. Majority of patients had cholesteatoma with granulation diseases (72%) followed by granulation diseases (16%). Involvement of disease in attic, aditus, antrum and mesotympanum were found to be high in majority of cases (82%) with high percentage of necrosis of incus (56%). Conclusion: The primary disease found in patients undergoing canal wall down mastoidectomy (CWDM) was cholesteatoma combined with granulation in72%, granulation in 16% and cholesteatoma in12%.
