The active middle ear implant’s floating mass transducer (FMT) is placed on themiddle ear structure or coupled to the inner ear fluid. Since the device is not directly placed onthe external auditory canal, patients are free from feedback phenomenon and occlusion effectresulting from hearing aids. A 66-year-old patient suffered from bilateral hearing loss. The patienthad difficulties in adapting to a conventional hearing aid because of feedback phenomenonin the right ear. The patient underwent a middle ear implantation using a CliP-Coupler to connectstapes head and FMT in the left ear.
