title: Vascular pulsations on impedance audiometry as a sign of a third-mobile window lesion.
abstract: OBJECTIVE
  Description of a new audiometric sign of a third-mobile window lesion.
  
  
  METHODS
  Subject with known superior canal dehiscence.
  
  
  METHODS
  Diagnostic.
  
  
  METHODS
  Results of impedance audiometry testing.
  
  
  RESULTS
  Vascular pulsations seen on impedance audiometry on dehiscent side.
  
  
  CONCLUSIONS
  Vascular pulsations seen on impedance audiometry may indicate a third-mobile window lesion in the inner ear.
