Abstract

Objective: The aim of this study was to describe the successful operative management of a patient with superior semicircular canal dehiscence syndrome, using the transmastoid approach under local anaesthesia.

Methods: The transmastoid approach was used to plug the superior semicircular canal.

Results: Post-operatively, the patient experienced significant improvement in his symptoms of sound- and pressure-induced dysequilibrium, autophony and imbalance.

Conclusion: Successful operative management of superior semicircular canal dehiscence can be achieved via the transmastoid approach under local anaesthesia.
