Abstract

Background: 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.

Objective: 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.

Materials and methods: 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.

Results: 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.

Conclusion: 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.

[骨导助听器的非手术固定可能性:使用外压与粘合板耦合的比较]。
背景:骨传导听力系统适用于无法通过气导助听器或手术进行适当治疗的传导性或合并性听力损失患者。这些听力系统可以通过手术植入,也可以通过骨导眼镜或硬质或软质头带可逆连接。非手术且无压力的替代方法是通过粘接板固定:本研究的目的是比较通过新型粘接板和软头带固定助听器时,助听器传递到乳突的能量。此外,还对粘接板的舒适度和耐用性进行了评估:共对 30 名受试者进行了测试。通过加速度计测量传递的能量,该加速度计记录了上颌牙齿处的声能。在受试者佩戴或不佩戴助听器佩戴粘接板最多 7 天后,使用调查问卷对佩戴舒适度、固定时间(直到粘接板松动)和皮肤反应进行检查。此外,还对皮肤反应进行了临床评估:结果:在 0.5、1 和 2 kHz 频率下,软头带的传输能量有明显差异。另一方面,对粘合板的美观度和佩戴时间的满意度和接受度都很高,没有出现皮肤过敏现象:结论:2 千赫以下传输能量的差异可能是由于粘接板的压力不足造成的。在对语音处理器进行适当调整后,这种差异可能会得到弥补。基于粘板在舒适度方面的积极特性,它可以作为软头带的替代品。

期刊介绍: HNO is an internationally recognized journal and addresses all ENT specialists in practices and clinics dealing with all aspects of ENT medicine, e.g. prevention, diagnostic methods, complication management, modern therapy strategies and surgical procedures. Review articles provide an overview on selected topics and offer the reader a summary of current findings from all fields of ENT medicine. Freely submitted original papers allow the presentation of important clinical studies and serve the scientific exchange. Case reports feature interesting cases and aim at optimizing diagnostic and therapeutic strategies. Review articles under the rubric ''Continuing Medical Education'' present verified results of scientific research and their integration into daily practice.
