Bone-conduction hearing devices (BCHD) can provide hearing solutions in settings where middle ear pathology is rife.
Describe functional hearing outcomes and device use of children fitted with BCHD.
Retrospective review of 79 children fitted with BCHD between January 2017 and May 2022. Outcomes included device use and subjective reports measured with the Parents' Evaluation of Aural/Oral Performance of Children (PEACH) and the Teachers' Evaluation of Aural/Oral Performance of Children (TEACH). Analysis of variance established association between mean data logging and type and degree of hearing loss. Thematic analyses were done for qualitative outcomes.
Average usage was 7.0 h/day (5.4 SD; range 0.1-24). PEACH ratings indicated 93.3% of children wore their BCHD 'always' or 'often', with 80% displaying Typical auditory performance at 1-month follow-up. TEACH ratings indicated 84.2% of children wore their BCHD 'always' or 'often', with 78.9% showing typical auditory behaviour. Increased usage was noted for conductive, mixed, moderate and severe hearing losses. There was a mean delay of 17.2 months (23.4 SD; range 0-90) between age of diagnosis and fitting. Thematic analyses identified two main themes: advantages and barriers to BCDH use.
Average device use fell short of the internationally recommended 10 h/day. Higher BCHD use was associated with higher functional listening performance scores. Long waiting times for medical or surgical intervention for conductive hearing losses can delay BCHD fitting.Contribution: Limited information is available to examine outcomes in children fitted with BCHD.
骨导式听力设备（BCHD）可在中耳病理普遍存在的情况下为患者提供听力解决方案。
描述使用骨导式听力设备（BCHD）为儿童患者提供助听效果和设备使用情况。
回顾性分析了 2017 年 1 月至 2022 年 5 月期间为 79 名儿童患者配置 BCHD 的情况。研究结果包括设备使用情况和使用父母对儿童听觉/口语表现评估（PEACH）和教师对儿童听觉/口语表现评估（TEACH）的主观报告进行评估。方差分析确定了平均数据记录与听力损失类型和程度之间的关联。对定性结果进行了主题分析。
平均使用时长为 7.0 小时/天（5.4 标准差；范围 0.1-24）。PEACH 评估结果显示，93.3%的儿童“经常”或“总是”佩戴其 BCHD，80%的儿童在 1 个月随访时表现出典型的听觉表现。TEACH 评估结果显示，84.2%的儿童“经常”或“总是”佩戴其 BCHD，78.9%的儿童表现出典型的听觉行为。在传导性、混合性、中度和重度听力损失患者中，使用时长有增加的趋势。从诊断到适配之间的平均时间延迟为 17.2 个月（23.4 标准差；范围 0-90）。主题分析确定了两个主要主题：BCHD 使用的优势和障碍。
设备平均使用时长未达到国际推荐的 10 小时/天。较高的 BCHD 使用与较高的功能性听力表现评分相关。传导性听力损失的医疗或手术干预等待时间较长，可能会延迟 BCHD 的适配。
为评估使用 BCHD 的儿童患者的结果提供了有限的信息。
