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.
