Abstract
OBJECTIVE: Description of a new audiometric sign of a third-mobile window lesion. PATIENTS: Subject with known superior canal dehiscence. INTERVENTION(S): Diagnostic. MAIN OUTCOME MEASURE(S): Results of impedance audiometry testing. RESULTS: Vascular pulsations seen on impedance audiometry on dehiscent side. CONCLUSION: Vascular pulsations seen on impedance audiometry may indicate a third-mobile window lesion in the inner ear.
