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.

Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Normal Heart Sounds
S1 (First Heart Sound)-
S1 is made by the closure of the mitral and tricuspid valves (atrioventricular valves), marking the beginning of systole.
S2 (Second Heart Sound)-
S2 is made by the closure of the aortic and pulmonic valves (semilunar valves), marking the end of the systole.
