Re-fixation Saccade at Video-Head Impulse Test in Patients with Sudden Sensorineural Hearing Loss

Objectives: This study was performed to evaluate characteristics and their prognostic value of video-head impulse test (vHIT) in sudden sensorineural hearing loss (SSNHL) with vertigo.Methods: Of the 612 patients a diagnosis SSNHL from 2010 2018, 110 (18.0%) vertigo 39 (6.4%) vHIT results were recruited. The evaluated for pure-tone average (at initial, 1-month, 6-month visit), presence re-fixation saccade gains at vHIT, canal paresis (CP) ccaloric test.Results: Patients (+) showed higher averages than those (‒) on initial follow-up audiograms. improvement less group group. There no significant difference recovery between normal gain decreased gain. CP groups according saccade.Conclusions: Concurrent is negative factor function SSNHL. Re-fixation may suggest widespread damages both cochlea vestibule, leading poor prognosis.
