title: Vestibular-evoked myogenic potentials after superior semicircular canal obliteration.
abstract: OBJECTIVE
  To analyse vestibular evoked myogenic potentials (VEMPs) characteristics in patients with superior semicircular canal dehiscence syndrome (SCDS) after surgical plugging.
  
  
  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.
  
  
  CONCLUSIONS
  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.
  
  
  CONCLUSIONS
  VEMPs are essential in both preoperative planning and postoperative monitoring of patients with SCDS.
