作者在6年中(1983～1988)对244个小于3岁儿童进行了电生理学检查。凡6个月以上的儿童均先进行主观测听,包括语声、发声玩具、气、骨声刺激检查和鼓室图及镫骨肌反射。电生理检查中,73%只需脑干诱发电位检查即可确定和证实主观测听结果(1岁以下婴儿在自然睡眠和镇静下进行,1～3岁者常需全麻),只有27%须在全麻下进行耳蜗电图检查。耳蜗电图的资料表明:①越近蜗尖区阈值反应的潜伏期越长,而对高强度反应潜伏期甚短,当刺激强度减弱时,动作电化潜伏期突然
The authors performed electrophysiological examinations of 244 children younger than 3 years old in 6 years (1983 ~ 1988). All children over six months were subject to subjective listening and listening tests, including vocalization, vocal toys, gas, bone stimulation, tympanogram and stapedius reflexology. In the electrophysiological examination, 73% of the patients only need to check the brainstem evoked potentials to confirm and confirm subjective listening results (infants under 1 year of age are under natural sleep and sedation, patients with general anesthesia usually require 1 to 3 years old), only 27% Need to be under general anesthesia for cochlear electrogram. The data of cochlear electrocautery showed that: (1) The longer the latency to the threshold reaction in the cochlear region, the shorter the latency to high-intensity response. When the stimulus intensity was weakened,
