title: The BAHA HC200/300 in comparison with conventional bone conduction hearing aids.
abstract: A retrospective study was performed on 89 patients from a consecutive series who received a BAHA HC200/300 after having previously used conventional bone conduction hearing aids. The patients' performance with the BAHA HC 200/300 was compared to their performance with conventional bone conduction hearing aids. The patients were divided into two groups, depending on the time of implantation (before or after May 1992). The patients in group 1 (long-term users) were asked to fill in a questionnaire, the same one as they had filled in at the initial BAHA fitting more than 5 years previously. The answers were compared to their original opinions and difference scores were calculated. The long-term clinical results from group 1 are also presented. Although they are encouraging, the patients' opinion about the BAHA deteriorated somewhat over time. The audiometric results of group 2 were highly comparable with those of group 1. This confirms the positive results with the BAHA found in previous studies.
