There is no significant difference in speech recognition scores obtained with the Vibrant Soundbridge and the open-fit hearing aid. However, the Vibrant Soundbridge may be superior to open-fit hearing aids in improving hearing at high frequencies (4-8 kHz).
To assess whether an improvement in speech recognition conferred by Vibrant Soundbridge is more marked than that afforded by open-fit hearing aids in patients with sloping high frequency sensorineural hearing loss (SNHL).
This study had a self-control prospective design. Seven patients aged 21-62 years with sloping high frequency SNHL were recruited into the study. Each patient received a Vibrant Soundbridge middle ear implant (Vibrant MED-EL) and wore an open-fit hearing aid (Danavox, DOT 10). Speech recognition tests were performed according to protocols suggested by árpád Götze's speech definition test in Hungarian language. In the first session, conventional hearing thresholds (unaided pure tone thresholds) were measured. In the second session, the aided sound-field threshold, speech understanding score and functional gain obtained using middle ear implants and open-fit hearing aids were determined after programming of the devices.
Regarding speech recognition scores, there were no significant differences between data obtained with the middle ear implant and those with the open-fit hearing aid.
使用振动声桥和开放式助听器所获得的言语识别分数没有显著差异。然而，振动声桥在改善高频（4 - 8千赫）听力方面可能优于开放式助听器。
评估在患有高频陡降型感音神经性听力损失（SNHL）的患者中，振动声桥带来的言语识别改善是否比开放式助听器更为显著。
本研究采用自身对照前瞻性设计。招募了7名年龄在21 - 62岁之间的高频陡降型SNHL患者参与研究。每位患者接受了振动声桥中耳植入物（Vibrant MED-EL）并佩戴了开放式助听器（Danavox，DOT 10）。言语识别测试按照匈牙利语的阿尔帕德·格策言语定义测试所建议的方案进行。在第一阶段，测量常规听力阈值（未佩戴助听器时的纯音阈值）。在第二阶段，在对设备进行编程后，确定使用中耳植入物和开放式助听器所获得的助听听阈、言语理解分数和功能增益。
关于言语识别分数，中耳植入物所获得的数据与开放式助听器所获得的数据之间没有显著差异。
