简要总结
Patients with unilateral transmission hypoacusis due to otosclerosis undergoing stapedectomy surgery will be prospectively included.
They will be undergoing a free field vocal audiometry using the Oldenburg MATRIX software to evaluated the squelch effect gain between audiometry before and after 9months after surgery.
Our hypothesis is to show a squelch effect with the rehabilitation of the binaural audition.
详细描述
Otosclerosis is one of the main causes of transmission hypoacusis. It can be treated with stapedectomy surgery.
But the understanding ability in noise has not been really studied. The Oldenburg MATRIX test is a well know test in audiology and allow to study the understanding in noise.
This study included all the patients coming in our center for stapedectomy for otosclerosis with controlateral audition under 30 decibels (dB) loss.
They will all undergo the MATRIX test in three situations: vocal material and noise from the front of the patient (S0N0 situation); vocal material from the front and noise from the bad-earing side (S0N-90 situation); vocal material from the front and noise from the good-earing side (S0N90 situation).
