Abstract
|
|
|
|
Cervical and ocular vestibular evoked myogenic potential (VEMP) may be one of the important clinical tools for evaluation of vestibular function. Cervical VEMP evaluates saccule and reflects the functional status of inferior vestibular nerve combining with vertical head impulse test. Ocular VEMP assesses utricle function and provides superior vestibular nerve function in addition to horizontal head impulse test and caloric test. Currently, the clinical implications of VEMP have been expanded to estimate disease severity and location, differentiate diverse vestibular disorders, and predict the prognosis. In present review, we discuss the findings of VEMP according to the lesion location from peripheral vestibular dysfunction to central vestibulopathy and disease characteristics from monophasic transient disorders to chronic progressive disorders.
