Vibrant soundbridge middle ear implant in otosclerosis: technique - indication

With our growing experience with the Vibrant Soundbridge (VSB) middle ear implant, the question emerged of its indication in mixed hearing loss due to advanced otosclerosis. We describe the VSB implantation technique in primary otosclerosis performed together with a stapedotomy piston procedure. Hearing results under headphone and free-field conditions show that the stapedotomy piston procedure closes the air-bone gap as expected and that the VSB provides comparable gain to that usually recorded for pure sensorineural hearing loss. The gains of the two procedures add up. These results open the field of mixed hearing loss to the VSB middle ear implant.
