Auditory Brainstem Response in Patients of Tinnitus with Sensorineural Hearing Loss

Abstract

Tinnitus is defined as phantom auditory perception without corresponding acoustic or mechanical correlates in cochlea. Existing evidence on its physiological basis is wide ranging, but its origin is still under exploration. To objectify this subjective phenomenon, Auditory Brainstem response test is used. The primary purpose of our study was to ascertain any significant difference in auditory electrophysiological response parameters in sensorineural hearing loss with tinnitus group when compared to controls (normal hearing subjects). Secondary aim was to find correlation of these parameters with degree of hearing loss and severity of tinnitus. This was a case control study conducted in the department of Otorhinolaryngology in tertiary care hospital, New Delhi over a period of one and half years. The study comprised of one hundred and sixty patients out of which, fifty-five patients were sensorineural hearing loss with tinnitus and fifty-one patients were normal hearing subjects. General medical and audiological assessment was done. Significant increase in latency of wave I, III, V and increase in inter peak latency of I–III, III–V, I–V was observed in tinnitus with sensorineural hearing loss group when compared to controls. It was reported that on increasing degree of hearing loss, there was increase in latency of wave I, III, V and increase in inter peak latency of wave I–III, I–V in the former group.
