作者改进一种非损伤性鼓膜外电极,成功地记录110名年龄在37周孕龄至6岁的正常儿耳蜗电图,并获得满意出波率.120dBpeSPL时,SP和AP-N_1波出波率均为100%,AP-N_2达90.8%以上.AP-N_1潜伏期与同时记录的脑干听觉诱发电位波Ⅰ一致.对20名正常青年测得的AP、SP波潜伏期及波幅与文献报道的其他电极相似.7名年长儿和8名青年进行本电极与成人常用的Coats电极对比测试,出波率平均增高23.3%;波幅也较高,并能在包括新生儿在内的任何年龄完成耳蜗电位图记录,且有无痛、省时、无需麻醉等优点
The authors modified a non-invasive eardrum electrode to successfully record 110 normal children’s electrocochleograms aged 37 weeks to 6 years of age and obtained a satisfactory wave-rate. At 120 dBpe SPL, SP and AP-N 1 wave The rate of AP-N_2 was over 90.8%, and the latency of AP-N_1 was consistent with that of simultaneously recorded brainstem auditory evoked potential wave I. The latency and amplitude of AP and SP wave measured by 20 normal youth were similar to those reported in the literature Similar to other electrodes, seven older children and eight young adults performed an average 23.3% increase in wave output over the Coats electrode, which was commonly used in this and adult adults; the amplitude was also high and could be achieved at any age, including the newborn Cochlear potentiometer record, and painless, time-saving, without anesthesia and other advantages
