AbstractThe study was undertaken to define the characteristics of spontaneous eardrum perforation in acute otitis media. Eighty (29.5 per cent) out of 271 children with acute otitis media had eardrums which perforated. An increased incidence of perforation was associated with a previous history of otitis media.All perforations were small and limited exclusively to the pars tensa. In 85 per cent of the patients, the perforation was located in the anterior-inferior quadrant. It had smooth margins enabling free drainage of pus and was associated with a favourable clinical course. In the remaining 15 per cent of the cases, the perforation was located in the posterior-superior quandrant. It had a nipple-like shape with a tiny opening that did not allow pus to drain sufficiently from the middle ear.The perforation closed in 94 per cent of the patients within one month. The healing process was gradual and following perforation closure, there was evidence of middle ear effusion for some time before normal aeration was regained.

Tympanometric evaluation using an otoadmittance meter and X-Y plotter was performed on 129 ears of 70 children with history of recurrent acute otitis media, or evidence otoscopically of persistent middle ear effusion, or both. Myringotomy, performed immediately following the tympanometric procedure, confirmed the presence or absence of effusion. Following myringotomy, tympanometric patterns, as shown by susceptance and conductance tracings at 220 and 660 Hz, were identified and middle ear pressures and otoadmittance peak values were determined. These findings were compared and criteria were developed which best determined the presence or absence of effusion. The results revealed the following: 1) High negative middle ear pressure is not necessarily a reliable indicator of middle ear effusion. 2) Tympanometry can be used reliably as an indicator of effusion. A combination of pattern classification and susceptance criteria enabled correct prediction of effusion in 93% of these children. One pattern at B660 was found to be pathognomonic of effusion. 3) In general, otoadmittance at 660 Hz appears to be a better indicator of effusion than 220 Hz.

Ear Effusion

Acute suppurative otitis media (AOM) is a common, painful condition affecting 20% of children under 4 years at least once a year,1 and perhaps more in infancy when clinical examination is most difficult. Infectious complications such as mastoiditis, meningitis and cerebral abscess are now rare, but chronic middle ear effusion and hearing loss remain common. Hearing loss may persist long after the infective episode,2 and may impair learning.

Ear Effusion

Raman microspectroscopy was used to characterize and identify the three main pathogens that cause acute otitis media (AOM)in vitro. Cultured middle ear effusion from patients was studied and results suggest the potential of using this technique to aid in accurately diagnosing AOM and providing physicians with bacterial identification to guide treatment.

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.
