Vestibular Evoked Myogenic Potentials

Abstract

Vestibular evoked myogenic potentials (VEMPs) are a key component of the vestibular test battery. Their value is with assessment of the otolithic organs (saccule and utricle) and divisions of the vestibular nerve. Cervical and ocular VEMPs (cVEMPs and oVEMPs) are the two commonly used procedures. cVEMP tests the saccule and inferior vestibular nerve pathway, while the oVEMP evaluates the utricle and the superior vestibular nerve. The addition of vestibular evoked potentials to the conventional vestibular test battery provides for a more detailed picture and thus more comprehensive diagnostic information on the entire peripheral balance organ and the central processing involved.
