To evaluate the efficacy and satisfaction of bone-anchored hearing aids (BAHA) in patients with outer and middle ear deformities.
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.
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.
BAHA remains one of the most reliable methods of auditory rehabilitation and improves quality of life for patients with ear deformities.
评估骨锚式助听器（BAHA）对外耳和中耳畸形患者的疗效及满意度。
7例双侧小耳畸形伴外耳道闭锁患者及3例单侧小耳畸形伴双侧中耳畸形患者先佩戴软带BAHA数月，随后接受单侧BAHA植入。比较未佩戴助听器、佩戴软带BAHA及植入BAHA患者的平均纯音听阈和言语测听测试结果。使用BAHA使用者问卷评分及格拉斯哥儿童受益量表（GCBI）来衡量患者满意度和主观健康受益情况。
未佩戴助听器患者的平均纯音听阈为（64.8±5.9）dBHL，佩戴软带BAHA患者为（30.2±3.7）dBHL，植入BAHA患者为（20.3±3.9）dBHL。佩戴软带BAHA患者纯音听阈平均下降（36.2±8.0）dBHL，植入BAHA后又额外下降（12.2±3.4）dBHL。在45dBHL声场中，未佩戴助听器患者的言语识别率（SDS）平均提高（3.00±1.07）%，植入BAHA患者为（89.39±5.83）%。在65dBHL声场中，未佩戴助听器患者的SDS为（57.55±10.30）%，植入BAHA患者为（91.19±4.16）%。在45dBHL和65dBHL测试时，SDS平均提高分别为（88.21±6.86）%和（38.04±7.56）%。未佩戴助听器时的声音接受阈（SRT）为（63.1±5.9）dBHL，植入BAHA患者为（24.7±3.5）dBHL。SRT平均提高（39.6±6.2）dBHL。BAHA应用问卷显示患者满意度极高。总体受益评分为35.59±14.35。
BAHA仍然是最可靠的听觉康复方法之一，可改善耳部畸形患者的生活质量。
