Prospective Study To Assess Sensorineural Hearing Loss Following Middle Ear Surgeries

Abstract

Background: Sensoryneural Hearing Loss (SNHL) may result from drill generated noise produced during middle ear surgeries. Though it is suggested by many it is not properly documented. Objective: This study was carried out to assess sensoryneural hearing loss following middle ear surgeries. Methods: 60 patients were studied and their bone conduction levels were recorded pre-operatively and post-operatively on first, seventh and twenty-first days. The presence or the absence of SNHL was determined by comparing between the two. Results: Pre operative and post operative bone conduction levels were compared by using paired-t test. The p values post operatively first day (p-0.484), seventh day (p 0.716), twenty-first day (p-0.665) were insignificant. Interpretation and conclusion: In our study there was no sensorineural hearing loss following middle ear surgeries. No significant correlation was found between duration of discharge, type of surgery, duration of surgery and SNHL.
