Abstract:
BACKGROUND AND OBJECTIVES: Vestibular neuritis predominantly affects the superior branch of the vestibular nerve, resulting in vertigo. Acute viral labyrinthitis occurs when an infection affects both vestibulo-cochlear nerve and labyrinth, resulting in hearing changes as well as vertigo. The purpose of study is to identify there is a difference of cervical vestibular evoked myogenic potentials (cVEMP) and ocular VEMP (oVEMP) in patients with vestibular neuritis and acute viral labyrinthitis. MATERIALS AND METHODS: cVEMP and oVEMP tests using 500-Hz tone-burst stimuli were performed on patients with vestibular neuritis and acute viral labyrinthitis. Pure tone audiometry, caloric test and subjective visual vertical (SVV) were performed in all patients. We compared the VEMP results, SVV, caloric test in patients with vestibular neuritis and acute viral labyrinthitis. RESULTS: Abnormal cVEMP responses were detected in 2 (20%) patients with vestibular neuritis and 5 (100%) patients with labyrinthitis. Abnormal oVEMP responses were detected in 9 patients (90%) with vestibular neuritis and 5 (100%) patients with labyrinthitis. oVEMP abnormalities is correlated with caloric test and subjective visual vertical in patients with vestibular neuritis and labyrinthits. CONCLUSION: Our results shows that the response of cVEMP and oVEMP between patients with vestibular neuritis and acute viral labyrinthitis is different. We can infer that oVEMP response to air-conducted sound is different vestibular origin compared to cVEMP and may originate from utricle.
