The primary objective of this study is to measure objective, functional outcomes of patients undergoing cartilage cap occlusion surgery for a dehiscent superior semicircular canal.
One option for managing a dehiscent superior semicircular canal is surgical intervention. One of the surgical techniques is the transmastoid and tegmen mini-craniotomy cartilage cap occlusion of the dehiscent superior semicircular canal.

placement of a cartilage cap over the dome of the superior semicircular canal through a combined transmastoid and tegmen mini- craniotomy approach.
objective improvement
The primary outcome measure will be the subsequent (3 month) FGA scores between the control group and the surgery group to assess any objective improvement attributable to surgery
Time frame: baseline to 3 months
ABC Scale
Secondary objective outcome measures will be changes in conductive hearing loss and changes in cervical VEMP thresholds between the two groups at the 3-month interval. Secondary subjective outcome measures will be ABC Scale and VAS scores between the two groups at 3 months.
