鼓岬电刺激诱发声感的试验,一般采用正弦波或脉冲波的电信号作刺激源,用于了解全聋病人是否还有足够可用的听神经纤维,为电子耳蜗植入术挑选病人。对信号的识别能力,尤其是对复杂信号的识别能力,都是靠术后的测试了解,病人不能在术前对电子耳蜗的效果有切实的体验,术后常感不理想,不能坚持使用,训练。为了探寻术前测试信号识别能力的方法,在鼓岬电刺激试验中引用了言语和音乐的电信号,进行正常耳蜗和病变耳蜗的比较,以了解耳蜗在正常和病变情况下信号识别能力的差异,以及病变耳蜗识别信号所依据的主要特征。受试者和测试方法受试者按耳蜗状态分为病变组和正常组。病变组为感音神经性聋,37人,62耳,年龄10—64岁,包
Drumhead Electrical stimulation of sensory testing, the general use of sinusoidal or pulsed electrical signals as a stimulus for understanding the deaf patients have enough available auditory nerve fibers for cochlear implant surgery to select patients. Recognition of the signal, especially for complex signals recognition, are based on postoperative test to understand that the patient can not have a realistic experience on the effect of the electronic cochlea before surgery, often feel unsatisfactory, can not adhere to use, training. In order to explore the pre-test signal recognition ability of the method, the drum promontory stimulation test using speech and music signals, the normal cochlear and diseased cochlear comparison to understand the normal and lesion cochlear signal recognition ability difference , As well as the main features on which the diseased cochlear recognition signal is based. Subjects and Test Methods Subjects were divided into diseased and normal groups according to cochlear status. Lesions were sensorineural hearing loss, 37, 62 ears, aged 10-64 years, package
