Bone-anchored hearing aids (BAHAs) are indicated for use in children with bilateral microtia or chronic suppurative otitis media, which precludes the use of conventional hearing aids.
Nineteen consecutive children using BAHAs were reviewed retrospectively. Outcome measures included the long-term stability of BAHAs, frequency of adverse dermatological reactions at the implant site, and audiologic thresholds.
Osseointegration was achieved in 95% of patients. One patient lost the implant fixture secondary to direct head trauma. Site revisions were required for only two patients secondary to soft-tissue overgrowth at the abutment site. There were no differences between pre-implantation and post-implantation bone or air conduction thresholds, but there was a statistical improvement in the post-implantation aided thresholds.
Utilization of paediatric BAHAs, in a distinct population, is a reliable and successful method for audiologic rehabilitation.
骨锚式助听器（BAHA）适用于双侧小耳畸形或慢性化脓性中耳炎患儿，这些患儿无法使用传统助听器。
回顾性分析19例连续使用BAHA的患儿。观察指标包括BAHA的长期稳定性、植入部位不良皮肤反应的发生率以及听力阈值。
95%的患者实现了骨整合。1例患者因头部直接外伤导致植入固定装置丢失。仅2例患者因基台部位软组织过度生长需要进行部位修复。植入前和植入后骨导或气导阈值无差异，但植入后助听阈值有统计学改善。
在特定人群中使用儿童BAHA是一种可靠且成功的听力康复方法。
