Vibrant Soundbridge (VSB, MED-EL, Innsbruck) Active middle ear implants (AMEI) can benefit patients who are unable to use conventional hearing aids (HA) due to medical reasons, discomfort or unsuccessful rehabilitation. Long-term prospective longitudinal studies are lacking on the VSB notably for conductive and mixed hearing loss. The main aim of the present study was to prospectively assess aided hearing benefits in a 60-month, long-term study including conductive and mixed hearing loss adults implanted with the VSB. The secondary objective was to compare the hearing results according to the Floating Mass Transducer (FMT) site (Round/oval window (RW/OW) vs incus/stapes) and the type of pathology responsible for the hearing loss (Inflammatory vs non-inflammatory disease, ID vs NID).
