dc.description.abstractBilateral vestibulopathy (BV) is a known cause of chronic vestibular syndrome. With the video head impulse test (VHIT), we can now evaluate all six semicircular canals independently and establish BV subgroups based on canal gain patterns. Background/objectives: To assess canal gain patterns for BV with VHIT, and evaluate subgroups with regard to sex, age, and hearing loss. Methods: A retrospective chart review was performed of all patients who underwent a VHIT between January 2021 and July 2024. Patients with decreased lateral canal gains, bilaterally, were included. Results of canal gains, VHIT patterns, audiometry, and videonystagmography (VNG) results were reviewed. Results: 101 cases were included. Patients were 75.5 ± 13.1 years old and 64.4% were women.Various VHIT patterns were observed; the most frequent being decreased canal gains across all six canals (44.6%), followed by a mix of canals with decreased gains with no clear pattern (34.7%). Decreased gains limited to the lateral canals were rare. We did not observe any significant difference between subgroups with regard to gender or age. Concomitant hearing loss was common (89.6%). A trend was noted, suggesting that severity of hearing loss increased with the number of affected canals. An abnormal VNG test was common (73.3%).
