Superior semicircular canal dehiscence (SSCD) syndrome is a rare disease characterized by sound and pressure induced vertigo accompanying vertical-torsional nystagmus, caused by dehiscence or absence of a bone overlying the superior semicircular canal. Patients show various extent of symptoms related to hearing and balance impairment, according to the degrees of bony dehiscence of superior semicircular canal. The authors have experienced a 41-year-old male patient with the chief complaint of severe hyperacusis and dizziness. The patient was finally diagnosed as left SSCD, and the symtoms were successfully treated surgically by repairing SSCD via middle cranial fossa approach. We thus report a rare case of SSCD syndrome accompanying not only dizziness but also severe hyperacusis and successfully managed by surgical method via middle cranial fossa approach.
