Superior semicircular canal dehiscence (SSCD) is associated with conductive hearing loss, autophony, and pressure/sound induced vertigo. Patients who are symptomatic may elect to undergo surgical intervention.

Here, Dr. Kaylie demonstrates the transmastoid approach to repairing SSCD. This approach affords the opportunity for an outpatient procedure to expose and plug the canal around the defect.
