Abstract
Objective: To evaluate the outcome of round window (RW) with or without oval window (OW) tissue reinforcement in the management of superior canal dehiscence (SCD).
Method: Chart reviews were perfomed for patients with symptomatic SCD that underwent this window reinforcement procedure. Preoperative and postoperative audiometry, vestibular myogenic evoked potentials (VEMP), and presence of a positive Tullio and Hennebert’s sign were recorded. Patient questionnaires were administered to assess symptomatic relief following the procedure.
Results: Twenty-five chart reviews from 5 tertiary centers revealed that most patients experienced reduction of symptoms and were satisfied with the results. A comprehensive analysis will be presented.
Conclusion: Tissue reinforcement of the windows(s) may reduce some of the symptoms associated with SCD, perhaps by mitigating some of the presumed “third window” effect of the dehiscence. Most patients were grateful for the benefits provided by the procedure and the avoidance of a craniotomy or mastoidectomy.
