Comparison of Auditory Brainstem Response Results in Normal-Hearing Patients With and Without Tinnitus

Abstract

To evaluate electrophysiologically the auditory nerve and the auditory brainstem function of patients with tinnitus and normal-hearing thresholds using the auditory brainstem response (ABR).

Contribuição do potencial evocado auditivo em pacientes com vertigem

“…The increase in absolute latencies with unaltered interpeak intervals is a common finding in conductive hearing loss 23,9 and it was also found in patients with Ménière 24 . Our findings on the latency increase are very similar to the studies which BAEP results showed significant increase in waves I, III and V latencies in 43% of the normal hearing patients complaining of tinnitus when compared to the Control Group, as well as interpeak values within normal ranges 21 . The present investigation was also similar to latency increase findings from waves I, III and V in patients with vertigo alone or vertigo associated with tinnitus.…”

Noise-induced tinnitus: auditory evoked potential in symptomatic and asymptomatic patients

“…Similar results have been reported in other studies, with increased wave I latency (16), significantly increased wave III latency (17,18) and increased absolute latencies of waves I, III and V, with interpeak latencies I-III, I-V and III-V within normal limits (11). These results may be related to differences in the neural transmission of acoustic stimuli (19), as these latencies were slightly increased in the Tinnitus group in our study.…”

A Study of Brainstem Auditory Evoked Responses in Normal Hearing Patients with Tinnitus

“…However, ABR absolute and interpeak latencies were prolonged in some tinnitus patients and this agreed with Kehrle et al [1], Rosenhall and Axelsson [14], Ikner and Hassen [15], Maurizi et al [11] and Lemaire and Beutter [16].…”
