Chronic Suppurative Otitis Media (CSOM) is the major cause of hearing impairment, mainly conductive type of hearing loss. The occurrence of Sensori neural Hearing Loss (SNHL) in Chronic Suppurative Otitis Media (CSOM) is controversial. This study aims to investigate the pattern of Sensori neural Hearing Loss (SNHL) in patients diagnosed with Chronic Suppurative Otitis Media (CSOM) with & without cholesteatoma & to estimate the correlation between various degree of sensori neural hearing impartment and the auditory evoked potential wave characteristics, computed using pure tone audiometry & brainstem evoked response audiometry in patients with chronic suppurative otitis media with & without cholesteatome. In Method 100 patients with unilateral Chronic Suppurative Otitis Media (CSOM) with normal contralateral ear were included in the study. The affected ears formed the Chronic Suppurative Otitis Media (CSOM) group & the normal ears formed the control group. Detailed audiometric and Brainstem Evoked Response Audiometry (BERA) findings were recorded and analysed. In Results No significant difference was observed across the wave I - III, III - V and I - V interwave latency values of normal ears and ears with Chronic Suppurative Otitis Media (CSOM) with or without cholesteatoma. Significant difference was observed across the pure tone average values of air conduction and bone conduction pure tone of normal ears and ears with Chronic Suppurative Otitis Media (CSOM) with or without cholesteatome. Good correlation was obtained across the waves I – III, III - V & I - V interwave latency values of normal ears and ears with Chronic Suppurative Otitis Media (CSOM) with or without cholesteatoma. Poor correlation was obtained across the air conduction pure tone average thresholds of normal ears and ears with Chronic Suppurative Otitis Media (CSOM) with or without cholesteatoma.
