Fourteen patients with conductive or mixed hearing loss were fitted with 16 BAHA. Three patients had congenital malformation of the auditory canal. Eleven patients had sequelae after bilateral chronic otitis media. All implants were osseointegrated. In 81% of the patients, no skin reactions around the abutment occured. The subjective evaluation was investigated by means of a questionnaire. All patients preferred their BAHA to their previous hearing aid and 93% are globally satisfied. Patients were evaluated in sound field, preoperatively and postoperatively using warble tones (mean on the average pure tone threshold at 0.5 1 and 2 kHz of 51.5 dB unaided to 22.6 dB aided with BAHA), speech reception threshold (mean of 51.1 dB unaided to 21.9 dB aided with BAHA) and speech discrimination. In three cases, we find an "antenna" effect, an improvement in reception wearing the Titanium screw and the abutment without the hearing aid connected.
14例传导性或混合性听力损失患者佩戴了16枚骨锚式助听器（BAHA）。3例患者存在外耳道先天性畸形。11例患者有双侧慢性中耳炎后遗症。所有植入物均实现骨整合。81%的患者在基台周围未出现皮肤反应。通过问卷调查进行主观评估。所有患者都更喜欢他们的BAHA而不是之前的助听器，93%的患者总体满意。术前和术后在声场中使用啭音对患者进行评估（平均纯音阈值在0.5、1和2千赫兹时，未佩戴助听器时为51.5分贝，佩戴BAHA时为22.6分贝）、言语接受阈值（未佩戴助听器时平均为51.1分贝，佩戴BAHA时为21.9分贝）以及言语辨别能力。在3例病例中，我们发现了一种“天线”效应，即在未连接助听器的情况下佩戴钛螺钉和基台时听力有所改善。
