Description VN = vestibular neuritis; VM = vestibular migraine; VP = vestibular paroxysmia; vHIT = video head impulse test; VNG = video-nystagmography; ENG = electronystagmography; VOG = video-oculography; VEMPs = vestibular evoked myogenic potentials; SCDS = superior canal dehiscence syndrome; BPPV = benign paroxysmal positional vertigo; BVL = bilateral vestibular loss; PPPD = persistent postural perceptual dizziness (no specific test is helpful to make this diagnosis, but patients often develop PPPD as the result of another poorly treated or anxiety-provoking vestibular disorder - e.g., vestibular migraine, BPPV or vestibular neuritis) - Not usually helpful + May be helpful ++ Very helpful 1 In the acute setting when spontaneous nystagmus is present 2 During provocative maneuvers (including Valsalva, pinched-nose Valsalva, tragal compression, loud sounds, Dix-Hallpike/supine roll test, hyperventilation) 3 Rotary chair may show slightly low time constants and gains with unilateral vestibular loss, and may show prolonged time constants in migraine 4 Depending on the posterior fossa localization, there may be caloric weakness with some strokes 5 VEMPs may assist in the localization of inferior versus superior division vestibular neuritis 6 Neuroimaging is needed (MRI internal auditory canal [IAC]) protocol w/wo) in migraine and Meniere's cases where there is diagnostic uncertainty or atypical features. In SCDS, CT temporal bones is the test of choice. For vestibular paroxysmia, heavily T2-weighted CISS or FIESTA imaging. In BVL, if the cause is clearly ototoxicity from gentamicin for instance, neuroimaging will not be helpful. Otherwise, neuroimaging is essential.
