title: Vestibular evoked periocular potentials in Meniere's disease after glycerol testing.
abstract: OBJECTIVE
  The present investigation was specifically designed to evaluate the clinical application of vestibular evoked periocular potentials (VEPPs) in the diagnosis of endolymphatic hydrops.
  
  
  METHODS
  We compared the results of the traditional pure tone audiometry glycerol test with those of the vestibular evoked myogenic potential (VEMP) glycerol test and the VEPP glycerol test in 22 patients affected by unilateral endolymphatic hydrops.
  
  
  RESULTS
  Some patients had positive depletive tests with both VEMPs and VEPPs, and other patients had positive tests with either VEMPs or VEPPs.
  
  
  CONCLUSIONS
  Our outcomes confirmed that vestibular evoked potentials represent a useful additional diagnostic tool in the diagnosis of endolymphatic hydrops. The role of VEPPs in this particular issue was not inferior to that of VEMPs. The outcomes also suggested that not only the saccule, but also the utriculus, may be involved in the genesis of VEPPs.
