Objective To evaluate patients' opinions of the bone-anchored hearing aid (BAHA) compared with a conventional hearing aid.
Design Prospective study with two questionnaires. Questionnaire A consisted of questions that compared patients' previous hearing aid with the BAHA. Questionnaire B consisted of questions about the patients' experiences with the hearing aids.
Patients Sixty-five consecutive patients who had used conventional hearing aids.
Setting Tertiary referral center.
Intervention A percutaneous titanium implant in the temporal bone for the BAHA.
Main Outcome Measure Qualitative descriptive results of questionnaire A and difference scores from questionnaire B comparing conventional hearing aids and the BAHA.
Results Patients favored the BAHA to the conventional bone-conduction hearing aid. Patients with BAHA reported a significant improvement in speech recognition in quiet and in noise, in sound quality, and in comfort (P<.01). The results with the BAHA compared with the air-conduction hearing aid were ambiguous for speech recognition, but all the patients reported a decrease in ear infections.
Conclusion The BAHA is a good alternative for the conventional bone-conduction hearing aid if a patient can no longer use an air-conduction hearing aid.
