Cartilage cap occlusion technique for dehiscent superior semicircular canals.

OBJECTIVE Assessment of a cartilage cap occlusion of dehiscent superior semicircular canals via a transmastoid and tegmen mini-craniotomy approach surgical technique. STUDY DESIGN Retrospective case review. SETTING Tertiary referral center. PATIENTS Thirty-seven patients over a 2 year time period underwent cartilage cap occlusion of a dehiscent superior semicircular canal. INTERVENTION Therapeutic. MAIN OUTCOME MEASURE Subjective improvement and/or resolution of dizziness postoperatively. RESULTS Of 37 patients, 29 (78%) felt much better and had resolution of their dizziness. Of 37 patients, 5 (14%) felt some definite improvement, although not complete resolution. Two patients (5%) felt their dizziness was neither better nor worse, and 1 patient (3%) felt dizziness was worse after surgery. CONCLUSION The cartilage cap occlusion technique of dehiscent superior semicircular canals via a transmastoid and tegmen mini-craniotomy approach is a good option for managing symptomatic patients with a dehiscent superior semicircular canal.
