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.
