The BAHA (bone-anchored hearing aid) remains the most reliable method of auditory rehabilitation for patients with congenital aural atresia and improves hearing outcome and quality of life in these patients who are otherwise unable to benefit from traditional hearing aids. New techniques are being developed, such as fully implantable hearing devices, and will have to prove their efficacy and safety in this indication.
To evaluate the audiological results and patient satisfaction after rehabilitation of congenital aural atresia using the BAHA.
Sixteen patients suffering from bilateral congenital aural atresia were implanted with unilateral BAHA. Preoperative air- and bone-conduction thresholds and air-bone gap (ABG), preoperative sound reception threshold (SRT), postoperative aided thresholds, implantation complications, patient satisfaction, and the APHAB questionnaire were collected.
After a mean follow-up period of 6.5 years, 15 patients were still using their device. Each patient had an average improvement of 33 ± 7 dB. Closure of the ABG within 15 dB of the preoperative bone-conduction thresholds occurred in 10 patients. Adverse skin reactions appeared in 50% of patients over 6.5 years of follow-up. Eleven of the 12 patients used their BAHA for more than 8 h per day.
骨锚式助听器（BAHA）仍然是先天性外耳道闭锁患者听觉康复最可靠的方法，可改善这些无法从传统助听器中获益的患者的听力结果和生活质量。新技术正在不断研发，如完全植入式听力设备，且必须在该适应症中证明其有效性和安全性。
评估使用BAHA对先天性外耳道闭锁患者进行康复治疗后的听力学结果及患者满意度。
16例双侧先天性外耳道闭锁患者接受了单侧BAHA植入。收集术前气导和骨导阈值及气骨导间距（ABG）、术前声音接受阈值（SRT）、术后助听阈值、植入并发症、患者满意度以及APHAB问卷。
平均随访6.5年后，15例患者仍在使用该设备。每位患者平均改善了33±7 dB。10例患者的ABG在术前骨导阈值的15 dB范围内闭合。在6.5年的随访中，50%的患者出现了皮肤不良反应。12例患者中有11例每天使用BAHA超过8小时。
