title: Superior semicircular canal dehiscence with a large tegmental defect.
abstract: We report on the presentation and clinical manifestations of superior semicircular canal dehiscence in association with a large defect of the tegmen tympani in a 41-year-old woman with no previous history of trauma. Based on this case we recommend that clinicians consider the possibility of superior semicircular canal dehiscence in patients presenting with symptoms associated with tegmen defects.
