Answer

The pathology and treatment of superior canal dehiscence includes the following:

  • Superior canal dehiscence syndrome is an entity in which the superior semicircular canal has become dehiscent in the floor of the middle fossa. Patients tend to report that loud sounds or pressure changes exacerbate their vertiginous symptoms.

  • The diagnosis is typically made with a high-resolution computed tomography scan. Surgical treatment currently involves a middle fossa craniectomy with diagnosis and patching of the dehiscent canal. [3]
