ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the efficacy and satisfaction of bone-anchored hearing aids (BAHA) in patients with outer and middle ear deformities.</p><p><b>METHODS</b>Seven patients with bilateral microtia and aural atresia, and three patients with unilateral microtia and bilateral middle ear malformation were fitted with soft-band BAHA for a few months, followed by receiving unilateral BAHA implantation. Mean pure-tone thresholds and speech audiometry tests results were compared among patients without hearing aid, with soft-band BAHA, and with implanted BAHA. Scores from the BAHA users' questionnaires and Glasgow children's benefit inventory (GCBI) were used to measure patient satisfaction and subjective health benefit.</p><p><b>RESULTS</b>The mean pure-tone thresholds of the patients were (64.8 ± 5.9) dBHL for those without hearing aid, (30.2 ± 3.7) dBHL for those with soft-band BAHA, and (20.3 ± 3.9) dBHL for those with implanted BAHA. The average decline in pure-tone threshold was (36.2 ± 8.0) dBHL for those with soft-band BAHA, and an additional decline of (12.2 ± 3.4) dBHL was achieved with implanted BAHA. The average gains in speech discrimination scores (SDS) were (3.00 ± 1.07)% for those without hearing aids and (89.39 ± 5.83)% for those with implanted BAHA in sound field of 45dBHL. SDS were (57.55 ± 10.30)% for those without hearing aids and (91.19 ± 4.16)% for those with implanted BAHA in sound field of 65dBHL. The average gains in SDS were (88.21 ± 6.86)% and (38.04 ± 7.56)% tested with 45dBHL and 65dBHL respectively. Sound reception thresholds (SRT) without hearing aids were (63.1 ± 5.9) dBHL and (24.7 ± 3.5) dBHL for those with implanted BAHA. The average gains in SRT was (39.6 ± 6.2) dBHL. The BAHA application questionnaire demonstrated excellent patient satisfaction. The general benefit score was 35.59 ± 14.35.</p><p><b>CONCLUSION</b>BAHA remains one of the most reliable methods of auditory rehabilitation and improves quality of life for patients with ear deformities.</p>
