OBJECTIVES: To examine audiometric outcomes, symptom control rates, and complication rates following semicircular canal plugging for superior semicircular canal dehiscence syndrome.
STUDY DESIGN: Retrospective chart review.
SETTING: Private, neurotologic tertiary referral center.
SUBJECTS AND METHODS: Patients undergoing semicircular canal plugging for superior semicircular canal dehiscence syndrome from January 1, 2007, to December 31, 2012. Pre- and postoperative audiometry, vestibular testing, operative findings, and clinical symptoms were assessed through chart review.
RESULTS: A total of 24 ears underwent a canal plugging procedure during the study period for superior canal dehiscence syndrome. Pre- and postoperative air conduction pure-tone averages were 21.1 and 22.5 dB (P = .42, not significant [NS]). The average pre- and postoperative word recognition scores were 95.8% and 95.1% (P = .48, NS). Vestibular evoked myogenic potential data showed reduced thresholds in 7 patients with canal dehiscence. Complications were limited to a single, temporary facial weakness. Complete symptom improvement was noted in 35.7% of all patients, while at least partial symptom improvement was found in over 80% of patients.
CONCLUSION: Semicircular canal plugging procedures are associated with excellent hearing outcomes and may reduce preoperative symptoms in patients with superior semicircular canal dehiscence.
