Bone conduction hearing systems are used for patients with conductive or combined hearing loss who cannot be adequately treated with air conduction hearing aids or surgery. These hearing systems can be surgically implanted or reversibly attached using bone conduction eyeglasses or a rigid or soft headband. A nonsurgical and pressure-free alternative is fixation via an adhesive plate.
The aim of this study was to compare the energy transferred from the hearing aid to the mastoid when attached via a new adhesive plate versus via a soft headband. In addition, the comfort and the durability of the adhesive plate was evaluated.
A total of 30 subjects were tested. The transferred energy was measured by accelerometer, which recorded the sound energy at the maxillary teeth. Wearing comfort, fixation duration (until plate becomes loose), and the skin reaction were examined using a questionnaire after the subjects had worn the adhesive plate with and without hearing aid for a maximum of 7 days. The skin reaction was also assessed clinically.
There was a significant difference in the transferred energy in favor of the soft headband at 0.5, 1, and 2 kHz. On the other hand, there was a high level of satisfaction and acceptance regarding the aesthetics and the wearing time of the adhesive plate, without skin irritations.
The difference in the transferred energy up to 2 kHz is probably due to the lack of pressure from the adhesive plate. This could possibly be compensated after appropriate adjustment of the speech processor. Based on the positive properties of the adhesive plate in terms of comfort, it could be used as an alternative to the soft headband.
骨传导听力系统用于患有传导性或混合性听力损失且无法通过气导助听器或手术得到充分治疗的患者。这些听力系统可以通过手术植入，或者使用骨传导眼镜或刚性或软性头带进行可逆性连接。一种非手术且无压力的替代方法是通过粘附板进行固定。
本研究的目的是比较通过新型粘附板与软性头带连接时，助听器传递到乳突的能量。此外，还评估了粘附板的舒适度和耐用性。
共测试了30名受试者。通过加速度计测量传递的能量，该加速度计记录上颌牙齿处的声能。在受试者佩戴粘附板（有无助听器）最长7天后，使用问卷检查佩戴舒适度、固定持续时间（直到板松动）和皮肤反应。还进行了临床皮肤反应评估。
在0.5、1和2千赫兹时，传递的能量存在显著差异，软性头带更具优势。另一方面，对于粘附板的美观性和佩戴时间，受试者满意度和接受度较高，且无皮肤刺激。
高达2千赫兹的传递能量差异可能是由于粘附板缺乏压力。在对言语处理器进行适当调整后，这可能得到补偿。基于粘附板在舒适度方面的积极特性，它可以用作软性头带的替代品。
