To describe an active auditory rehabilitation method (clip vibroplasty) for conductive or mixed hearing loss in cases of a preserved stapes superstructure.
After temporal bone experiments, the new clip vibroplasty was clinically used in 4 patients with chronic otitis media.
A new titanium double clip device (clip vibroplasty) was developed for a standardized and effective coupling of the floating mass transducer of the Vibrant Soundbridge to the intact stapes. Temporal bone experiments using laser Doppler vibrometry were performed to evaluate the device's acoustic efficiency. The audiologic outcomes of the first 4 patients were analyzed. The subjective benefits and satisfaction were assessed using the standardized International Outcome Inventory for Hearing Aids in all patients.
Transfer characteristics of laser Doppler vibrometry experiments; audiologic outcomes of the 4 patients.
In the temporal bone experiment, coupling of the FMT using the titanium double clip support produced transfer characteristics across all tested frequencies comparable to our former total ossicular reconstruction prosthesis or an optimal round window application. The intraoperative application of the clip vibroplasty was uneventful in all cases. No signs of prosthesis dislocation were noted within the follow-up period of approximately 12 months. The audiologic outcome of the first patients showed good hearing gain in pure-tone and speech audiometry, with results that are unobtainable using a conventional air conduction hearing aid.
The concept of a partial ossicular reconstruction prosthesis vibroplasty using a titanium clip support entails a straightforward procedure similar to a classic partial ossicular reconstruction prosthesis tympanoplasty. The unoccluded ear canal and the superior auditory performance offer an advantageous application of this "power clip" in cases of chronic middle ear dysfunction.
描述一种针对镫骨上部结构完整的传导性或混合性听力损失的主动听觉康复方法(夹振法)。
经过颞骨实验后,新的夹振法在 4 例慢性中耳炎患者中进行了临床应用。
为了标准化和有效地将 Vibrant Soundbridge 的浮动质量换能器耦合到完整的镫骨,开发了一种新的钛双夹装置(夹振法)。使用激光多普勒测振仪进行了颞骨实验,以评估该设备的声学效率。分析了前 4 例患者的听力学结果。所有患者均使用标准化的国际助听效果问卷评估主观获益和满意度。
激光多普勒测振实验的传递特性;4 例患者的听力学结果。
在颞骨实验中,使用钛双夹支架耦合 FMT 可产生跨所有测试频率的传递特性,与我们以前的全听骨重建假体或最佳的圆窗应用相当。在所有病例中,夹振法的术中应用均顺利完成。在大约 12 个月的随访期间,未发现假体脱位的迹象。前 4 例患者的听力学结果显示纯音和言语测听均有良好的听力增益,而使用传统的空气传导助听器则无法获得这些结果。
使用钛夹支架的部分听骨重建假体振子的概念涉及到类似于经典部分听骨重建假体鼓室成形术的简单手术。未阻塞的耳道和优越的听觉性能为这种“动力夹”在慢性中耳功能障碍病例中的应用提供了优势。
