This video demonstrates transmastoid superior semicircular canal occlusion. The transmastoid approach to superior SCC plugging has become the author surgical approach of choice. The superior semicircular canal is blue lined on both the ampulated and nonampulated sides of the dehiscence. This occludes the canal and functionally isolates the region of dehiscence. Following insertion of both plugs, the dura is gently mobilized to verify the dehiscence. This approach has the advantages of obviating a craniotomy, avoidance of temporal lobe retraction, familiarity of the approach for experienced otologists, and the ability to occlude the canal without manipulating the defect.
