摘要

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

波出波率均为100%

AP-N

达90.8%以上.AP-N

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

Abstract

A new extratynpanic electrode has been used successfully for the noninvasivc recording of electrocochleography (EcochG) in 110 normal children aged from 37 conception weeks to 6 years old. The presented rates of wave AP-N1 or SP both were 100%

and more than 90.8% for wave AP-N2 at 120 dBpeSPL. The latency of wave AP-Nt coincided with wave 1 in brainstem evoked potential recorded simultaneously. In 20 normal young adults

the latencies and amplitudes of wave APs or SPs were similar to the results reported in literatures using other kind of electrodes. Recorded by the electrode in 7 older children and 8 young adults

the presented rates of waves increased 23.3% and the amplitudes were higher as comparing with the results of Coats electrode which is a popular electrode for ECochG recording in adult. Present study showed that the. new electrode could successfully record the ECochG for the subjects at any age including neonate with the advantages as painless and easy to do without any anesthesia
