| 摘 要： | 为了研究电起搏器对失神经后不同时期环杓后肌的作用,我们选用14只狗分为喉返神经切断及吻合两组,分别在手术后即刻、2周、1、2、4、8、12个月进行观察,结果发现在神经切断及吻合即刻环杓后肌电刺激强度阈值较低(2伏),2周后达最高峰(7～10伏),4个月后,神经吻合组恢复到最初水平,神经切断组维持在6伏左右,并发现随病程延长环杓后肌萎缩加重.因此,电起搏器一定刺激强度在一定时间内对恢复萎缩环杓后肌的功能是有效的.

| Abstract: | In order to study the reactivity of denervated posterior cricoarytenoid muscle of different time to electrical stimulation and explore the possibility of clinical application of laryngeal pacing, 14 dogs were examined at 0,2 weeks, 1, 2, 4, 8, 12 months after recurrent laryngeal nerve was damaged by a 2 - cm neurectomy, or dissection followed by resuturing. The results showed that the minimum threshold level to induce vocal cord abduction was 2 V at time after nerve injury, and the threshold level reached the maximum (7 or 10 V)at 2 weeks after nerve injury , then decrease with time, and recover initial level in each case of nerve resuturing group or keep about 6 V in neurectomy group 4 months after nerve injury. It was concluded that electrical pacing was effective to restore function of denervated posterior cricoarytenoid muscle. |
