简介
骨锚式助听器（BAHA）系统使用骨整合钛植入物，通过颅骨将声音直接传播到内耳，绕过皮肤和皮下组织的阻抗。年仅 18 个月大的儿童已通过该设备恢复了听力。
目标
目标是评估患者选择标准的有效性、植入程序的安全性和有效性以及儿童 BAHA 植入后患者的满意度。
方法
对埃德蒙顿所有植入的儿科患者的记录进行了回顾性审查。 20 名患者接受了 25 个植入物，植入后随访时间为 6 个月或更长时间。平均随访时间为3年零7个月。
结果
在 20 个原始种植体中，3 个因创伤而丢失，而 2 个未能骨整合。全部成功重新植入。与种植体相关的并发症包括基台周围皮肤坏死的三例。所有患者和护理人员均表示，患者识别的聆听情境改善了 95% 以上。纯音平均值从术前听力较好的耳朵的平均值 49 dB 提高到 BAHA 设置为正常听力水平时的 16 dB。
结论
BAHA 为儿童传导性或混合性听力损失提供了一种安全有效的康复方法。我们的患者对他们的设备非常满意并持续使用。
INTRODUCTION
The bone-anchored hearing aid (BAHA) system uses an osseointegrated titanium implant to propagate sound directly to the inner ear through the bones of the skull, bypassing the impedance of the skin and subcutaneous tissues. Children as young as 18 months have had hearing rehabilitated with this device.
OBJECTIVES
The goals were to evaluate the efficacy of patient selection criteria, the safety and effectiveness of the implantation procedure, and the level of patient satisfaction after BAHA implantation in children.
METHODS
The records of all pediatric patients implanted in Edmonton were retrospectively reviewed. Twenty patients, who received 25 implants, with postimplantation follow-up of 6 months or greater, were included. The average follow-up was 3 years, 7 months.
RESULTS
Of 20 original implants, 3 were lost owing to trauma, whereas 2 failed to osseointegrate. All were successfully reimplanted. Complications related to the implants included three instances of skin necrosis around the abutment. All patients and caregivers reported greater than 95% improvement in patient-identified listening situations. Pure-tone averages improved from a mean of 49 dB for the better hearing ear preoperatively to 16 dB with the BAHA set at normal listening levels.
CONCLUSIONS
The BAHA provides a safe and effective means of rehabilitation of conductive or mixed hearing loss in the pediatric population. Our patients report a high level of satisfaction and continued use of their devices.
