Vascular pulsations on impedance audiometry as a sign of a third-mobile window lesion.
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.
