Objective: A pure tone audiomety analysis of patients with extracranial complications of chronic suppurative otitis media (ECCSOM). Material and methods: We retrospectively analyzed audiometric data performed before treatment from 63 patients with ECCSOM (56 single, 7 multiple complications) including groups of frequencies. Results: The greatest levels of hearing loss were noted for 6 and 8 kHz (79.0 and 75.7 dBHL) and for the frequency groups high tone average (76.1 dBHL). As regards the severity of hearing impairment in pure tone average the prevalence of complications was as follows: labyrinthitis (77.8±33.6 dBHL), facial palsy (57.1±14.3 dBHL), perilymphatic fistula (53.9±19.9 dBHL) and mastoiditis (42.2±9.5 dBHL) (p=0.023). Conclusions: Hearing loss in ECCSOM is dominated by mixed, high-tone, moderate type of hearing loss, most profound in labyrinthitis. In 11% of patients the complication causes total deafness.

AbstractObjectives:We evaluated the results of mobile, one stage, bilateral ear surgery conducted in Greenland, where chronic otitis media with and without suppuration is prevalent. The study aimed to increase the number of operations conducted and to reduce the cost of ear surgery in remote areas.Materials and methods:The study was longitudinal and prospective, with a two-year follow up. Seventeen East Greenlandic patients with bilateral chronic suppurative otitis media or chronic otitis media were selected. Their median age was 16 years; 53 per cent were female and 47 per cent male. Hearing was assessed using median air conduction pure tone average gain, and the ‘take rate’ (i.e. the percentage of total ears with a closed perforation) was evaluated.Results:All patients attended for follow up. Eighty-two per cent had at least one perforation closed, and the overall take rate was 65 per cent of the 34 ears. The median air conduction pure tone average gain after two years was 18 dB and 13 dB for the right and left ears, respectively. Fourteen patients (82 per cent) obtained an air conduction pure tone average hearing level of ≤25 dB in at least one ear. In total, 71 per cent of the patients were satisfied. There were no hearing hazards.Conclusions:The results of mobile, one stage, bilateral ear surgery conducted in Greenland for long-lasting chronic suppurative otitis media and chronic otitis media were acceptable and safe, and more ears underwent surgery at reduced cost compared with unilateral ear surgery.

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.

Middle Ear Infection

The prevalence rate of chronic suppurative otitis media is high and its treatment continues to be a challenge for the otorhinolaryngologists. Due to middle ear infection, there may be pain, hearing loss and spontaneous rupture of the eardrum which results in perforation. Infections can cause a hole in the eardrum as a side effect of otitis media. The patients suffering from ear perforation or having a hole in eardrum require preventing entry of water in the ear. This article describes the development of ear cap using additive manufacturing and TRIZ (a collaborative tool) to prevent the entry of water in the ear during chronic otitis media.

The aim of this study was to evaluate the success of stapedectomy in patients who have previously had a tympanoplasty because of chronic otitis media (COM). Fourteen patients from a private otology practice had undergone tympanoplasty for COM and subsequently underwent stapedectomy. Measurements were taken of the air-bone gap (ABG) closure and pure tone average (PTA) which showed hearing improvement. Patients had a mean 36.9 dB PTA hearing gain with 79 per cent closing the ABG to within 20 dB. The need for stapedectomy alone is a rare occurrence for patients with a history of COM requiring a tympanoplasty. Hearing improvement following stapedectomy in these cases was significant, although somewhat less than following traditional stapedectomy in otosclerosis alone.

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.

<p><strong>Background: </strong>Chronic suppurative otitis media (CSOM)-unsafe type or atticoantral disease or chronic otitis media-squamosal type is a commonly encountered bone eroding disease of the middle ear whose complications can be potentially fatal.</p><p><strong>Methods:</strong> Retrospective analysis of 80 patients who underwent mastoid exploration in the department of otolaryngology and head and neck surgery, NSCBMCH, Jabalpur between June 2016 and May 2017.</p><p><strong>Results: </strong>Unsafe CSOM is commoner in young males of 16-30-year age group. Foul smelling, scanty, purulent ear discharge was the commonest symptom (97.5%). Attic perforation was the most consistent otoscopic finding (47.5% cases). 15% of our patients had central perforations. Conductive hearing loss was most common (62%) followed by mixed hearing loss (23%) and sensorineural hearing loss (11%). Commonest complication encountered was mastoiditis (27 cases). Mastoidectomy with tympanoplasty was done in almost all cases (97.5%). Attic (96.2%), additus (90%), and antrum (86.2%) were commonly involved by disease process. Incus was found to be most susceptible to erosion (88.5%) while stapes was most resistant (36.25%).</p><p><strong>Conclusions:</strong> Unsafe CSOM presenting late warrant prompt diagnosis and surgical intervention. Unusual presentation like retropharyngeal abscess and trismus should raise suspicion of complicated unsafe CSOM in patients with history of otorrhoea. Canal wall down mastoidectomy with rehabilitation of hearing is the surgery of choice in patients who are unlikely to follow up regularly.</p>
