“…This technique have been also investigated in different inner ear pathologies like canal dehiscence syndrome [10], vestibular neuritis [11], Menière disease [8], benign paroxysmal positioning vertigo [12], profound sensory-neural hearing loss [13] and in otoneurosurgery (vestibular neurectomy and cochlear implant) [14]. VEMPs have been also applied in neurological disease: Herpes zoster oticus [15], multiple sclerosis [16], migraine [17], spinocerebellar degeneration [18].…”

“…27 Absent clickevoked VEMPs have also been reported in five of eight subjects with the Ramsay Hunt syndrome, in whom absence of VEMPs correlated with vertigo. 43 Bilateral vestibulopathy. VEMPs were absent bilaterally in two of three patients with idiopathic bilateral vestibulopathy.…”

A recent technique of assessing vestibular function, the vestibular-evoked myogenic potential (VEMP), is an otolith-mediated, short-latency reflex recorded from averaged sternocleidomastoid electromyography in response to intense auditory clicks delivered via headphones. Since their first description 10 years ago, VEMPs are now being used by investigators worldwide, and characteristic changes observed with aging and in a variety of peripheral and central vestibulopathies have been described. Additional methods of evoking VEMPs, which use air- and bone-conducted short-tone bursts, forehead taps, and short-duration transmastoid direct current (DC) stimulation, have been described, and these complement the original technique. Click-evoked VEMPs are attenuated or absent in a proportion of patients with vestibular neuritis, herpes zoster oticus, late Meniere disease, and vestibular schwannomas; their amplitudes are increased and thresholds are pathologically lowered in superior semicircular canal dehiscence presenting with the Tullio phenomenon. VEMPs evoked by clicks and DC are useful when monitoring the efficacy of intratympanic gentamicin therapy used for chemical vestibular ablation. Prolonged p13 and n23 peak latencies and decreased amplitudes have been observed in association with central vestibulopathy. VEMPs evoked by clicks are a robust, reproducible screening test of otolith function. DC stimulation enables differentiation of labyrinthine from retrolabyrinthine lesions; bone-conducted stimuli permit VEMP recording despite conductive hearing loss and deliver a relatively larger vestibular stimulus for a given level of auditory perception.

“…Unlike vestibular neuritis, absent caloric and VEMPs responses may be shown [32]. Therefore, the nerve trunks within the internal auditory canal are widely affected in HZO patients with vertigo.…”

SummaryBy easily stimulating the ear with loud sound and recording on tonically contracted neck muscles, vestibular evoked myogenic potential (VEMP) test can reflect inner ear function other than the cochlea and semicircular canal. This expands the test battery for clinicians to explore saccular disease, adding a potential usefulness to the sacculo-collic reflex. The ideal stimulation mode for VEMPs is as follows: 95 dB tone bursts, frequency 500 Hz, stimulation repetition rate 5 Hz, rise/fall time 1 ms, plateau 2 ms, binaural stimulation with bilateral recordings. Animal model using guinea pigs has been established, which sets the stage for useful future studies investigating VEMPs in guinea pigs that would appear to resemble human VEMP responses. Clinically, VEMP test has been widely used in central and peripheral vestibular disorders.
