Study of Multifrequential Impedancemetry in Pulsatile Tinnitus (MADMAN)

March 5, 2026 updated by: University Hospital, Bordeaux
This study intended to search for a relationship between the multifrequential admittancemetry and the pulsatile tinnitus.

Study Overview

Conditions

Detailed 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.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
patient with pulsatile tinnitus

Every participant of the study have to complete an Ear, Nose and Throat examination included a conventional audiometry, and a multifrequential admittancemetry.

if radio-interventional venous stenting is not indicated, an multifrequential admittancemetry will also be performed 3 months after the procedure.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Multifrequency admittancemetry
Time Frame: At Day 0 (inclusion)
G conductance peak width at 2000 Hz
At Day 0 (inclusion)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
compression maneuvers
Time Frame: At Day 0 (inclusion)
Evaluation of the effect of compression maneuvers on the width of the G 2000 peak of the IMF in venous or arterial pulsatile tinnitus, whether or not the maneuver is effective.
At Day 0 (inclusion)
Evaluation of the effect of interventional radiology
Time Frame: up to 3 month after inclusion (M3)
Evaluation of the effect of interventional radiology procedures such as transverse sinus stenting on MFI values.
up to 3 month after inclusion (M3)
success of radiointerventional treatment
Time Frame: up to 3 month after inclusion (M3)
Search for a predictive factor of success of radiointerventional treatment of venous pulsatile tinnitus: search for a threshold value of pre-operative G2000, separating two groups: success and non-success (groups defined by a THI (Tinnitus Handicap Index) divided by 2 in the success group).
up to 3 month after inclusion (M3)
