We included 9 patients implanted with Baha Attract. All our patients were evaluated by free field tonal audiometry, free field verbal audiometry and free field verbal audiometry with background noise, all the tests were performed with and without the device. To evaluate the subjective component of the implantation, we used the Glasgow Benefit Inventory (GBI) and Abbreviated Profile of Hearing Aid Benefit (APHAB). The auditive assessment with the device showed average auditive thresholds of 35.8dB with improvements of 25.8dB over the previous situation. Speech reception thresholds were 37dB with Baha Attract, showing improvements of 23dB. Maximum discrimination thresholds showed an average gain of 60dB with the device. Baha Attract achieves auditive improvements in patients for whom it is correctly indicated, with a consequent positive subjective evaluation. This study shows the attenuation effect in transcutaneous transmission, that prevents the device achieving greater improvements.
我们纳入了9名植入了巴哈吸引式骨导助听器（Baha Attract）的患者。所有患者均接受了自由声场纯音听力测试、自由声场言语听力测试以及有背景噪声情况下的自由声场言语听力测试，所有测试均在佩戴和不佩戴该设备的情况下进行。为评估植入的主观效果，我们使用了格拉斯哥效益量表（GBI）和助听器效益简表（APHAB）。佩戴该设备进行的听力评估显示，平均听阈为35.8dB，较之前的情况改善了25.8dB。使用巴哈吸引式骨导助听器时言语接受阈为37dB，改善了23dB。最大辨别阈显示，佩戴该设备平均增益为60dB。巴哈吸引式骨导助听器在适用患者中实现了听力改善，从而获得了积极的主观评价。本研究显示了经皮传输中的衰减效应，这使得该设备无法实现更大程度的改善。
