Abstract
Aim
Otosclerosis is one of the common otologic diseases. The mechanism and the probable site of vestibular involvement are not yet fully understood. The present study aimed to perform a comprehensive vestibular evaluation in patients with otosclerosis, compared to the cases without otosclerosis.
Materials and methods
patients underwent a comprehensive cochleovestibular evaluation, including audiometry, ocular and cervical vestibular evoked myogenic potential (o-VEMP and c-VEMP), video head impulse (vHIT) and caloric tests. The results were compared with those obtained from the non-otosclerosis control group.
Results
A total of 61 individuals were included in the study who were divided into two groups of the case (50.82%) and control (49.18%). The results showed that there was a significant difference in the mean vHIT gain between the case and control groups (P < 0.05). However, the mean gain was still within the normal range. Besides, the patients with otosclerosis had significant bilateral or unilateral weaknesses according to caloric test results. Moreover, their o-VEMP and c-VEMP results were significantly abnormal as well (P < 0.05).
Conclusion
Based on the results of the present study, the vestibular system even in asymptomatic cases, is affected by otosclerosis. Furthermore, it seems that the otolithic system has a higher chance of involvement, compared to the semicircular canals.
