Abstract
A review of the literature is presented to consider the role of round window (RW) operations in superior semicircular canal dehiscence (SSCD). Primary (PubMed) and secondary sources (TRIP, Cochrane database, Best Practice, and PubMed Clinical Queries) were used to identify relevant studies. Four original studies (three case series and one case report) were identified. All were retrospective reviews and used a number of subjective and objective outcome measures to assess the efficacy of a minimally invasive, transmeatal approach to perform RW surgery for SSCD. The current evidence suggesting that RW operations for SSCD are unlikely to replace more established surgical procedures as first-line treatment may be appropriate in a select group of patients. Further multicenter, randomized controlled trials are required to establish their efficacy in patients with SSCD.
