Auditory and vestibular findings in patients with vestibular migraine

Abstract

AbstractObjective: We aimed to report audiological and vestibular test results in patients with vestibular migraine (VM). We used a retrospective analysis study design in the setting of a tertiary referral neuro-otology center. Patients and methods: Data from 55 patients with the diagnosis of vestibular migraine were enrolled into the study. Comprehensive audiometry, electronystagmography (ENG) and vestibular myogenic evoked potentials (VEMP) were the interventions and main outcome measures were the degree and profile of hearing loss, speech discrimination, oculomotor gaze, saccades and pursuit abnormalities, as well as the presence of spontaneous, post head-shake and positional nystagmus. We also measured the caloric response peak slow phase velocity, asymmetry, failure of fixation suppression, and VEMP p12-n23 latency response. Results: Sensorineural hearing loss was present in 71% (39/55) of patients; 53% (29/55) had bilateral symmetrical loss, 9% (5/55) had bilateral asymmetrical loss and 9% (5/55) ha...
