About

This study intended to search for a relationship between the multifrequential admittancemetry and the pulsatile tinnitus.

Full description

The multifrequency admittancemetry is known to reflect several parameters of the middle ear and the external ear. More recently it appears to also reflect some parameters of the inner ear, such as the perilymph pressure. Furthermore, investigators do not know exactly the physiopathology of pulsatile tinnitus that are from veinous etiology. Modifications of the perilymphatic pressure could be implicated. Investigators intended to search for a relationship between these both theories.

Investigators will include every patient that consult to Ear, Nose and Throat unit of Bordeaux University Hospital with a pulsatile tinnitus trouble, and perform multifrequential admittancemetry. If a radio-surgical intervention is scheduled for a venous stenosis, the test will also be performed test after the surgery.

If there is no surgical intervention, no follow-up will be required.
