Previous Clinical Study

Problem In a previous clinical study, the incidence of chronic otitis media in cases of otosclerosis was reported to be less than that observed in patients without otosclerosis. Histopathologically, we can detect minimal changes such as histological otosclerosis or silent otitis media which are not detected clinically. The purpose of this study is to reveal the association of otosclerosis and chronic otitis media by evaluating human temporal bones, histopathologically. Methods 1235 human temporal bones were reviewed for this study. In order to match patients with otosclerosis, patients with chronic otitis media were limited to 16 to 92 years of age. The incidence of otosclerosis (clinical otosclerosis, histological otosclerosis) and chronic otitis media, either clinical (tympanic membrane perforation) or silent (without perforation) were analyzed. Results There was no statistically difference between the incidence of chronic otitis media in temporal bones with and without otosclerosis. Conclusion The association of chronic otitis media and otosclerosis appears to be a coincidental. Significance The incidence of chronic otitis media in cases of otosclerosis is not less than that observed in cases of chronic otitis media in cases without otosclerosis.

Temporal Bones

A review of 800 pathological temporal bones collected from autopsy cases revealed 333 (41.6%) to have some type of otitis media; purulent otitis media (52.5%), serous otitis media (6%), mucoid otitis media (4.5%), and chronic otitis media (36.9%). The 123 temporal bones with chronic otitis media were further studied and found to have granulation tissue, cholesteatoma, cholesterin granuloma, bone changes, and fibrosis. Other findings included tympanic membrane perforation, tympanosclerosis, metaplasia of the epithelium with subepithelial glandular formation, suppuration, labyrinthitis, and evidence of complications of chronic otitis media (meningitis, subdural abscess, brain abscess, petrositis, and endolymphatic hydrops). From this study it was concluded: 1) chronic otitis media occurred quite frequently, from a histological standpoint, in the absence of tympanic membrane perforation; 2) granulation tissue in temporal bones was found much more frequently in chronic otitis media than was cholesteatoma; and 3) complications and sequelae of otitis media tended to occur more commonly secondary to granulation tissue than to cholesteatoma.

Operative Findings

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.

<p class="abstract"><strong>Background:</strong> Tympanoplasty is a surgical procedure for closing the tympanic membrane perforation and reconstructing the tympanic membrane and hearing, commonly after trauma and chronic otitis media. The aim of the study was to compare the clinical and audiological outcomes of tympanoplasty with or without anterior tucking.</p><p class="abstract"><strong>Methods:</strong> In this prospective study, 50 patients with chronic otitis media (COM) were divided into two groups. Group 1 underwent type 1 tympanoplasty with anterior tucking method, and group 2 underwent type 1 tympanoplasty without anterior tucking. The result was measured on graft uptake and hearing outcome at 6 months postoperatively by performing pure tone audiometry.  </p><p class="abstract"><strong>Results:</strong> The hearing improvement was almost the same in both the groups. Graft uptake was good in type 1 tympanoplasty with tucking (96%) when compared to without tucking tympanoplasty (92%). Complications like residual perforation were seen in both groups equally. Anterior marginal blunting was noted (8%) in type 1 tympanoplasty with tucking.</p><p class="abstract"><strong>Conclusions:</strong> The hearing improvement of type-1 tympanoplasty with anterior tucking and without anterior tucking is the same. Type-1 tympanoplasty with anterior tucking has a better graft acceptance. The only disadvantage of type-1 tympanoplasty with anterior tucking is anterior marginal blunting.</p>

Rigid endoscope (0 degree) used to take an image for each perforation that analyzed by Autodesk Design Review 2013 program. Degree of hearing loss assessed by pure tone audiometry.

It observed that with increment of surface area of tympanic membrane perforation, the degree of conductive hearing loss increases (P value=0.000). This relationship expressed in a logarithmic equation. The mean hearing loss of posterior perforation was 1.7±0.5 dB for each 1% of perforation but in anterior perforation was 1.5±0.6 dB for each 1% of perforation (p value 0.185)<span lang="EN-IN">. </span></p><p class="abstract"><strong>Conclusions:</strong> In chronic otitis media, there is a quantitative logarithmic relationship between surface area of tympanic membrane perforation and degree of conductive hearing loss.
