传导性耳聋的矫治方法,以往是配戴常规助听器,但效果并不理想。作者报道了一种新的治疗方法─骨导助听,从原理、设计、选材、实验测试及临床应用等方面,总结了对颞骨振动器的研究和试制工作。颞骨振动器是利用声音-交变电磁场-机械振动的转换,由颞骨的振动引起听觉。设计的信号处理电路,具有较好的输入-输出特性、较高的保真度以及足够的增益。作者还对颞骨振动器的电磁激励线圈及植入磁体进行了研究,经实验测试,效果满意。初步临床应用表明,颞骨振动器可改善和提高传导性耳聋及混合性耳聋患者的听力,对先天性外耳道闭锁及中耳畸形病例,有独特的优点。受试者对语言频率的听阈提高26~30dB,符合临床应用要求。
Conductive deafness correction methods used to wear conventional hearing aids, but the effect is not satisfactory. The authors reported on a new treatment, bone-assisted hearing, that summarizes the research and trial work on the temporal bone shaker in terms of principles, design, material selection, experimental testing, and clinical application. Temporal bone vibrator is the use of sound - alternating electromagnetic field - mechanical vibration conversion, caused by the vibration of the temporal bone auditory. Designed signal processing circuit with better input-output characteristics, higher fidelity, and sufficient gain. The author also studied the electromagnetic excitation coil and implanted magnet of the temporal bone vibrator. After the experiment, the result was satisfactory. The preliminary clinical application shows that the temporal bone vibrator can improve and improve hearing loss in patients with conductive deafness and mixed deafness and has unique advantages in the cases of congenital external auditory canal atresia and middle ear malformations. Subjects hearing threshold of the language frequency increased by 26 ~ 30dB, in line with clinical requirements.
