Abstract:
BACKGROUND AND OBJECTIVES: This study aims to evaluate audiologic results and subjective satisfaction of bone anchored hearing aids (BAHA) patients. SUBJECTS AND METHOD: Preoperative air-conduction and bone-conduction thresholds, postoperative aided thresholds were measured for 14 patients. To evaluate patient satisfaction, two questionnaires derived from single sided deafness (SSD) questionnaire and Bern Benefit in SSD questionnaire were used. RESULTS: The mean age of patients, consisting of 8 males and 6 females, was 40.0+/-5.9 year. Ten patients (71%) received implantations for conductive or mixed hearing loss and 4 (29%) for SSD. The mean follow-up period was 27.8+/-5.6 months. The mean preoperative bone-conduction threshold of conductive or mixed hearing loss group was 21.4 dB and the mean air-conduction threshold was 65.4 dB. The mean bone-conduction threshold of SSD group was 60.0 dB and the mean air-conduction threshold was 105.9 dB. The postoperative aided threshold was significantly improved in conductive or mixed hearing loss group (p=0.005). The patients in the conductive or mixed hearing loss group showed more satisfaction with BAHA than those in the SSD group did, but the degree of satisfaction was not statistically significant (p=0.08 for questionnaire 1, p=0.12 for questionnaire 2). Patients with better preoperative bone-conduction threshold and patients with better preoperative speech discrimination score showed more satisfaction with BAHA in the questionnaire 1 (p=0.045, p=0.036). CONCLUSION: BAHA can be considered effective and beneficial for patients with conductive or mixed hearing loss and SSD. Further studies will be needed to choose the appropriate indications for BAHA, especially in SSD group in Korea.
