目的观察软带BAHA(Bone-anchored hearing aids,骨锚式助听器))在双侧先天性中外耳畸形患者的听力改善效果,探索其适应症。方法比较6例佩戴软带BAHA前后的双侧先天性中外耳畸形患者听力情况,包括日常交流情况、纯音(声场)测听或条件反射测听。结果 6例患者或家属反映佩戴BAHA后,日常交流情况明显改善,纯音(声场)测听或条件反射测听气导阈改善30.2dB。结论软带BAHA对双侧先天性中外耳畸形患者是一种简单、有效的听力解决方案。
Objective To report outcomes of the bone-anchored hearing aid (BAHA) softband in patients with bilateral congenital malformation of middle and outer ears. Method Auditory functions before and after BAHA softbands application were compared in 6 cases, including daily communication, pure tone (sound field) audiometry or condition reflex audiometry. Results Daily communication improved significantly in all 6 patients per patients or parents and audiometric thresholds improved by an average of 30.2 dB after BAHA softband application. Conclution The BAHA softband is a simple, effective hearing solution for bilateral congenital malormation of middle and outer ears.
