The bone-anchored hearing device (BAHD) was not introduced in China until 2010. To our knowledge, this is the first study to assess the efficacy of Chinese Mandarin-speaking patients with bilateral aural atresia.
To evaluate the speech recognition of Chinese Mandarin-speaking patients with BAHDs as well as patients' satisfaction using 2 questionnaires.
DESIGN, SETTING, AND PARTICIPANTS: A retrospective case review of 16 patients with bilateral aural atresia conducted at a tertiary referral center.
A BAHD was implanted during auricle reconstruction surgery or after the auricle was rebuilt. A surgical method to combine the BAHD implantation with the second stage of ear reconstruction was introduced.
Speech audiometry test and mean pure-tone threshold results were compared among patients with unaided hearing and those with BAHDs. Scores from the BAHD user questionnaire and Glasgow Children's Benefit Inventory (GCBI) were used to measure patients' satisfaction and subjective health benefit.
The mean (SD) speech discrimination scores measured in a sound field with a presentation level of 45 dB HL (hearing level) were 6.7% (7.4%) unaided and 86.5% (4.4%) with a BAHD. Scores with a presentation level of 65 dB HL were 56.5% (7.4%) unaided and 90.1% (3.4%) with a BAHD. The speech reception threshold was 60.6 (7.5) dB HL unaided and 24.7 (5.0) dB HL with a BAHD. The mean (SD) pure-tone threshold of the patients was 61.6 (7.8) dB HL unaided and 23.8 (5.9) dB HL with a BAHD. The BAHD application questionnaire demonstrated excellent patient satisfaction. The mean (SD) benefit score of GCBI was 45.6 (14.4).
For aural atresia, the BAHD has been one of the most reliable methods of auditory rehabilitation. It can improve the patient's word recognition performance and quality of life. The technique of BAHD implantation combined with auricular reconstruction in a 2-stages-in-1 surgery and the modified incision of patients with reconstructed auricle proved to be safe and effective.
骨锚定式听力设备（BAHD）直到 2010 年才在中国推出。据我们所知，这是第一项评估中文母语者双侧听小骨闭锁患者疗效的研究。
使用 2 种问卷评估接受 BAHD 的中文母语者双侧听小骨闭锁患者的言语识别能力以及患者的满意度。
设计、地点和参与者：对一家三级转诊中心的 16 例双侧听小骨闭锁患者进行回顾性病例分析。
在耳廓重建手术期间或耳廓重建后植入 BAHD。引入了一种将 BAHD 植入与第二期耳重建相结合的手术方法。
比较未助听和使用 BAHD 患者的言语测听测试和平均纯音阈值结果。使用 BAHD 用户问卷和格拉斯哥儿童福利指数（GCBI）评分来衡量患者的满意度和主观健康获益。
在 45dB HL（听力级）呈现水平的声场中测量的平均（SD）言语辨别分数为未助听 6.7%（7.4%），使用 BAHD 为 86.5%（4.4%）。在 65dB HL 呈现水平的评分分别为未助听 56.5%（7.4%）和使用 BAHD 90.1%（3.4%）。未助听的言语接受阈为 60.6（7.5）dB HL，使用 BAHD 为 24.7（5.0）dB HL。患者的平均（SD）纯音阈值为未助听 61.6（7.8）dB HL，使用 BAHD 为 23.8（5.9）dB HL。BAHD 应用问卷显示出极好的患者满意度。GCBI 的平均（SD）获益评分为 45.6（14.4）。
对于听小骨闭锁，BAHD 一直是最可靠的听觉康复方法之一。它可以提高患者的单词识别能力和生活质量。BAHD 植入联合两期手术中的耳廓重建技术以及对重建耳廓患者的改良切口被证明是安全有效的。
