A patient with superior semicircular canal dehiscence presenting with Tullio's phenomenon: a case report

INTRODUCTION Superior semicircular canal dehiscence represents a manageable cause of sound and pressure induced vertigo. This case highlights its presentation and investigation, including a review of the literature, and the authors' surgical technique used in its successful treatment. CASE PRESENTATION A 45-year-old Caucasian man presented with vertigo induced by sound or pressure. Subsequent investigation revealed dehiscence of the superior semicircular canal and the patient underwent a surgical repair. CONCLUSION Surgery to repair or resurface the dehiscence represents an effective treatment modality, offering a resolution of symptoms with no detrimental effect on hearing or long-term sequelae. A five-layer composite repair consisting of temporalis fascia - bone pate - conchal cartilage - bone pate - temporalis fascia has been found to be safe and effective.
