Recently, a new bone-conduction hearing aid has become available which can be connected percutaneously to the skull: the bone-anchored hearing aid or BAHA. Several clinical trials have shown its efficacy in patients with a conductive or mixed hearing loss. A second group of potential candidates are patients who suffer from an almost instantaneous skin reaction to any kind of earmould. Three such patients with a predominant sensorineural hearing loss were fitted with a BAHA. The aided free-field thresholds proved to be poor compared with the desired values using prescriptive rules. Speech recognition measured objectively (with tests) and subjectively (with a questionnaire) was comparable or better than with conventional bone-conduction hearing aids. Two patients were using their BAHA all day, whereas the third patient was only using it for a few hours per day. Although it did not produce optimal results, the BAHA seems to be the best solution for these patients.
最近，一种新型骨传导助听器问世，它可以经皮连接到颅骨：骨锚式助听器或BAHA。多项临床试验已证明其对传导性或混合性听力损失患者有效。另一类潜在适用人群是那些对任何类型耳模都会产生几乎即时皮肤反应的患者。三名主要为感音神经性听力损失的患者佩戴了BAHA。与使用规定规则得出的期望值相比，助听后的自由声场阈值较差。客观测量（通过测试）和主观测量（通过问卷调查）的言语识别能力与传统骨传导助听器相当或更好。两名患者全天使用BAHA，而第三名患者每天仅使用几个小时。尽管它没有产生最佳效果，但BAHA似乎是这些患者的最佳解决方案。
