title: [Cochlear implantation: clinical experience with 50 cases].
abstract: Fifty cochlear implantations with single-channel cochlear prosthesis were reported. The youngest patient was 12 and the eldest 50 years of age. Thirty patients were prelingually and twenty postlingually deaf. Surgical procedures consisted of a typical mastoidectomy and electrode placement via a posterior tympanotomy. The active electrode was introduced into the scala tympani through a hole on the promontory. Several problems regarding cochlear implantation which still have no unanimous opinion among otologists were discussed.
