Cochleovestibular Function of Trans-Mastoid Occlusion for Superior Semicircular Canal Dehiscence

To evaluate cochleovestibular outcomes following trans-mastoid superior semicircular canal (SSC) occlusion in patients with symptomatic superior semicircular canal dehiscence (SSCD) and third-window syndrome (TWS), and to characterize objective pre-and postoperative functional changes in a tertiary-center cohort.

Trans-mastoid superior semicircular canal occlusion appears to improve cochleovestibular outcomes in symptomatic SSCD; audiologists should be aware of expected post-operative hearing and balance profiles when managing these patients, but full interpretation requires review of the study's sample size and outcome data.

Superior semicircular canal dehiscence (SSCD) is an under-recognised cause of autophony (hearing one's own voice loudly), low-frequency conductive hearing loss, and vestibular symptoms, and reliable surgical outcome data directly guide multidisciplinary management.
