Objective: To analyse vestibular evoked myogenic potentials (VEMPs) characteristics in patients with superior semicircular canal dehiscence syndrome (SCDS) after surgical plugging. Matherials and methods: Five surgical plugging of SCD were performed on 4 patients presenting uni- or bilateral SCD. VEMPs were recorded before and after surgery. Results: Postoperative VEMP testing revealed in all cases a normalization of the response on the operated side. Discussion: Patients with SCDS typically have VEMPs with pathologically low thresholds and large amplitude potentials. VEMPs represent a screening investigation for SSCD and a valuable tool in the postoperative follow-up to confirm the successful repair of the dehiscence. In bilateral SSCD cases, VEMPs help to localize the worst side which is operated first. Conclusion: VEMPs are essential in both preoperative planning and postoperative monitoring of patients with SCDS.
