A Study of Auditory Brainstem Response Audiometry in Normal Hearing Patients with Tinnitus
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 6
Abstract
Tinnitus is thought to be an auditory phenomenon resulting from spontaneous neuronal activity somewhere along the auditory pathways either in the peripheral or central nervous system. The neuronal abnormalities underlying tinnitus are largely unknown. This study analysis the auditory brainstem responses in normal hearing patients with tinnitus. This study consisted of 100 patients divided into two groups. Group 1( control)-50 normal hearing patients without tinnitus. Group 2 ( study)- 50 normal hearing patients complaining of tinnitus. Both groups were subjected to full audiological history taking, otological examination, basic audiological evaluation and Auditory Brainstem Responses ( ABR) followed by calculation of absolute latencies of wave I, III and V and interpeak latencies between waves I-III, III-V and I-V. In the study group, 18 patients ( 36%) showed abnormal results in atleast one of the 6 parameters evaluated. The results of absolute latencies of wave I, III and V showed significant prolongation when compared with the control group. Furthermore, the interpeak I-III, III-V and I-V latencies were not significantly prolonged when compared with the control group.
