摘要

Idiopathic Sudden sensorineural hearing loss (ISSNHL) is an emergency otological disease that cause vertigo and imbalance, the aim of study was to investigate the function of otolith and semicircular canals in patients with unilateral ISSNHL with different vestibular tests and for subjective assessment such as Dizziness Handicap Inventory (DHI) and Activities-specific Balance Confidence (ABC) questionnaires. 66 participants (patients and controls) underwent vestibular testing. All Patients had ISSNHL and vertigo. The vestibular test were included cervical vestibular evoked myogenic potential (cVEMP), ocular vestibular evoked myogenic potential (oVEMP) and video head impulse test (vHIT). They also completed the DHI and ABC questionnaires. The cVEMP, oVEMP and vHIT were abnormal in 24 (72%), 22 (66%), and 11 (33.3%) cases, respectively. The DHI score was 27.33 ± 25.57 and ABC was 86.31 ± 18.67. The function of vestibular system was poorer related to control group. In patients with ISSNHL, damage to the vestibular system was observed especially in otolith system. We advise to evaluation vestibular system in addition to auditory system in patients with ISSNHL. VEMP tests and VHIT are useful tools for investigation the vestibular system.
