[Bone anchored auditory prosthesis. Indications, clinical and audiometric results].
Fourteen patients with conductive or mixed hearing loss were fitted with 16 BAHA. Three patients had congenital malformation of the auditory canal. Eleven patients had sequelae after bilateral chronic otitis media. All implants were osseointegrated. In 81% of the patients, no skin reactions around the abutment occured. The subjective evaluation was investigated by means of a questionnaire. All patients preferred their BAHA to their previous hearing aid and 93% are globally satisfied. Patients were evaluated in sound field, preoperatively and postoperatively using warble tones (mean on the average pure tone threshold at 0.5 1 and 2 kHz of 51.5 dB unaided to 22.6 dB aided with BAHA), speech reception threshold (mean of 51.1 dB unaided to 21.9 dB aided with BAHA) and speech discrimination. In three cases, we find an "antenna" effect, an improvement in reception wearing the Titanium screw and the abutment without the hearing aid connected.
