Vestibular Evoked Myogenic Potentials in Vestibular Migraine: Do They Help Differentiating From Menière's Disease?

Objective:To investigate whether both cervical and ocular vestibular myogenic potentials (cVEMPs and oVEMPs) to air-conducted sound (ACS) and bone-conducted vibration (BCV) can help to differentiate vestibular migraine (VM) and Meniere’s disease (MD).Study Design:Retrospective study.Settings:A tertiary referral center.Subjects and Methods:Twenty-eight patients with VM, 28 patients with definite unilateral MD, and 28 age-matched controls were included. Cervical VEMPs to 500 Hz ACS (cVEMPs-air) and 500 Hz BCV (cVEMPs-bone), oVEMPs to 500 Hz ACS (oVEMPs-air) and 500 Hz BCV (oVEMPs-bone), and caloric tests were performed. Results of these vestibular function tests were compared between the groups.Results:The prevalence of abnormality was significantly higher in VM than in controls only for the caloric test (P < .05). Asymmetry ratios (ARs) for cVEMPs-air and oVEMPs-air were significantly larger in VM than in controls (P < .05). Between VM and MD, the prevalence of abnormality was significantly different only ...
