Abstract
The objective of this study was to describe the operative management of posterior canal dehiscence. A transmastoid approach to and plugging of the posterior canal was performed for posterior semicircular canal dehiscence (PSCD). Postoperatively, the patient exhibited improvement in conductive hearing loss and vestibular symptoms. PSCD can cause symptoms identical to that of superior semicircular canal dehiscence. Successful PSCD plugging can be performed without visualization of the actual area of dehiscence.
