To evaluate the use of bone-anchored hearing aids (Bahas) in children with single-sided deafness.
Retrospective 3-year chart review.
Arkansas Children's Hospital, Little Rock, pediatric hospital serving children from birth to 21 years of age.
The study included 23 children (14 girls and 9 boys) with single-sided deafness (mean age, 12.6 years; age range, 6-19 years).
Two-stage Baha surgery with 6-month osseointegration was performed on children 5 years and older at a single institution. The Baha processor was placed 2 weeks after the second-stage surgery.
Results of the Hearing in Noise Test (HINT) and the Children's Home Inventory for Listening Difficulties (CHILD) questionnaires were compared before and after Baha activation in children with profound unilateral sensorineural hearing loss.
Preimplant mean HINT scores at speech-noise ratios of 0, +5, and +10 dB were 42%, 76%, and 95%, respectively. Postimplant mean HINT scores improved to mean speech-noise ratios of 82%, 97%, and 99% at 0, 5, and 10 dB, respectively. The CHILD scores also improved from mean preimplant ratings of 4.49 and 4.60 for patients and parents, respectively, to postimplant ratings of 6.90 and 7.10. Both teenagers (n = 15) and children younger than 13 years (n = 7) demonstrated improved HINT and CHILD scores. The complication rate was 17%.
Bone-anchored hearing aids are a durable treatment option that can achieve noticeable improvements in hearing in noise and in listening difficulties in children with profound unilateral sensorineural hearing loss.
评估骨锚式助听器（Baha）在单侧耳聋儿童中的应用。
回顾性3年病历审查。
阿肯色儿童医院，位于小石城，是一家为从出生到21岁儿童服务的儿科医院。
该研究纳入了23名单侧耳聋儿童（14名女孩和9名男孩）（平均年龄12.6岁；年龄范围6 - 19岁）。
在单一机构对5岁及以上儿童进行两阶段Baha手术，骨整合期为6个月。在第二阶段手术后2周佩戴Baha处理器。
对重度单侧感音神经性听力损失儿童，比较Baha激活前后的噪声环境下听力测试（HINT）结果以及儿童听力困难家庭问卷（CHILD）的得分。
植入前，在言语噪声比为0 dB、 +5 dB和 +10 dB时，HINT平均得分分别为42%、76%和95%。植入后，在0 dB、5 dB和10 dB时，HINT平均得分分别提高到言语噪声比的82%、97%和99%。CHILD得分也从患者和家长植入前的平均评分4.49和4.60分别提高到植入后的6.90和7.10。青少年（n = 15）和13岁以下儿童（n = 7）的HINT和CHILD得分均有所提高。并发症发生率为17%。
骨锚式助听器是一种持久的治疗选择，可使重度单侧感音神经性听力损失儿童的噪声环境下听力及听力困难状况得到显著改善。
