Description
Vestibular evoked myogenic potentials (VEMPs) were measured in 22 unilateral Menière patients with monaural and binaural stimulation with 250 and 500 Hz tone bursts. For all measurement situations signiWcantly lower VEMP amplitudes were on average measured at the aVected side compared to the unaVected side. Unilateral Menière patients have, in contrast to normal subjects, asymmetric VEMPs, indicating a permanently aVected vestibular (most likely otolith) system at the side of hearing loss. The diagnostic value of VEMP amplitude asymmetry measurement in individual patients is low, because of the large overlap of the VEMP amplitude asymmetry range for unilateral Menière patients with that for normal subjects.
