Operative management of a posterior semicircular canal dehiscence
Abstract
Objective: The objective of this study was to describe the operative management of posterior canal dehiscence.
Methods: A transmastoid approach to and plugging of the posterior canal was performed for posterior semicircular canal dehiscence (PSCD).
Results: Postoperatively, the patient exhibited improvement in conductive hearing loss and vestibular symptoms.
Conclusions: 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.
