Status of contralateral ear in chronic otitis media and role of diagnostic otoendoscopy in it’s assessment
Keywords:CSOM, Contralateral ear status
Background: Chronic suppurative otitis media doesn’t seem to be an isolated event that occurs in a particular patient. It seems rather be the product of a series of events constitutional of the individual. The precise and critical evaluation of both ears plays a fundamental role in the prognostic evaluation of the patient. Otoendoscopy is an upcoming day care procedure in the field of otology. It has several advantages over routine otoscopy for e.g. better resolution, wider field of vision, camera connectivity etc. We aimed to study the status of contralateral ear in chronic otitis media patients and evaluate the usefulness of diagnostic otoendoscopy.
Methods: A prospective study was done on CSOM patients attending ENT dept, SMCH using otoendoscopy, schuller radiography, pure tone audiometry, tympanometry and HRCT temporal bone. Data collected was analysed.
Results: A total of 80 patients were evaluated out of which 70% were male, otoendoscopy revealed features of a diseased contralateral middle ear in 80% of them, PTA suggested hearing loss in opposite ear in 80% of them, schuller’s radiography showed sclerosed opposite mastoid in 22.5% and CT scan needed to be done in 24 patients of which 10 had disease in opposite middle ear.
Conclusions: It is imperative from this study that evaluation of contralateral ear in chronic otitis media is important to unmask the hidden pathology and otoendoscopy is very useful in diagnosing it.
