Xomed 骨导助听器是一种电磁感应式助听装置。其内装置通过手术埋置于颞骨皮下,外装置则通过内装置中的磁铁吸引保持在位。声音处理器分耳级和体级两种。声音进入外装置后,由线圈产生电磁场,引起磁铁、颅骨、内耳的振动。其植入对象为双耳传导性耳聋,纯音骨导听阈(0.5、1、2 kHz)不超过25dB(HL)。在英国已有23例患者接受了 Xomed 骨导助听器。作者通过对其中18例患者的植入理曲、以前的助听方式、植入技术和手术问题,目前病人的使用状况和满意程度、纯音听阈、
Xomed bone conduction hearing aid is an electromagnetic induction hearing aid. The device is embedded in the temporal bone subcutaneously by surgery, while the external device is held in place by the magnet in the internal device. Sound processor sub-level and body level two. Sound into the external device, the electromagnetic field generated by the coil, causing the magnet, skull, inner ear vibration. The implanted object is binaural conductive deafness, pure tone bone conduction threshold (0.5,1,2 kHz) does not exceed 25dB (HL). Twenty-three patients in the UK have undergone Xomed bone conduction hearing aids. The author through 18 cases of patients implanted Liqui, the former hearing aids, implants and surgical problems, the current patient status and satisfaction, pure tone threshold,
