Differences in vestibulo‐ocular reflexes between vestibular neuritis and labyrinthitis

Objective To expand our understanding of the pathophysiological mechanisms underlying vestibular neuritis and labyrinthitis by identifying any difference in vestibulo-ocular reflex for each semicircular canal. Study Design Retrospective analysis. Setting The Department Otorhinolaryngology – Head Neck Surgery, Chosun University Hospital, from January 2015 to December 2021. Methods We included 23 27 patients who had been hospitalized. Pure-tone audiometry, a bithermal caloric test, video head-impulse test were performed within 5 days symptom onset. Results In group, mean gains decreased 0.51 ipsilesional horizontal canal 0.55 anterior canal, leading marked asymmetry, whereas gain posterior was relatively preserved at 0.85. 0.72 0.73 observed statistical differences incidence corrective saccades on side three canals between groups (p = .002 p .003 < .001 canal). receiver operating characteristic curve showed that pure-tone gain, asymmetry excellent parameters distinguishing neuritis. Conclusion Vestibular have different degrees patterns involvement canals, suggesting two distinct disorders may etiologies.
