title: Diagnostic value of frequency-associated vestibular-evoked myogenic potential responses in Ménière's disease.
abstract: Thirty subjects with unilateral Ménière's disease (MD) and 18 age-matched controls underwent cervical (cVEMP) and ocular vestibular-evoked myogenic potential (oVEMP) testing using bilateral air-conducted stimulation (ACS) with stimulus frequencies of 500 and 1,000 Hz. The aim of this study is to determine the diagnostic value of frequency-associated responses in MD using oVEMP and cVEMP following 500- and 1,000-Hz ACS. In healthy controls and unaffected ears, responses to 500 Hz were found better than 1,000-Hz ACS in both oVEMP and cVEMP, while ears with MD responded to 1,000-Hz ACS better than to 500-Hz ACS in oVEMP. In cVEMP tests, affected ears responded to 500-Hz and 1,000-Hz ACS equally. Amplitude ratios of 1,000/500 Hz in both oVEMP and cVEMP were successful in differing affected ears from unaffected ears and healthy controls. This study showed frequency alteration of oVEMP and cVEMP can be used as a diagnostic test battery in MD.
