PURPOSE: The aim of this study is to investigate auditory brainstem response (ABR) in patients with benign paroxysmal positional vertigo (BPPV) accompanied by tinnitus and to suggest possible interpretative hypotheses.
METHODS: Ninety individuals were included in the study. Individuals were separated into three groups: patients reporting tinnitus with BPPV (Group I), patients with BPPV (Group II), and a control group. The ABR test was applied at a low and at a high rate.
RESULTS: For patients reporting tinnitus with BPPV, tinnitus was found to be localized in the ear affected by BPPV. Tinnitus disappeared after therapeutic interventions in 23 individuals with tinnitus. The difference between the Wave V latency at high rate and Wave V latency at a low rate in the affected ears of all individuals with BPPV (Groups I and II) was significantly long. In the affected ears of all BPPV patients, at a high rate of ABR, the absolute latency of the Wave III was found to be significantly longer than for the control group.
CONCLUSIONS: Individuals with BPPV showed prolonged latencies in affected ears in a high rate of ABR without the effect of tinnitus. High rate of ABR in individuals with BPPV can be used to obtain preliminary information in cases where ischemia in the auditory pathways is suspected in BPPV formation.
