摘　　要：选用犬１５只，随机分成三组，进行了选择性再神经支配喉内收肌及外展肌功能重建的观察。两个实验组术侧声带最初恢复内收时间为术后３个月，最初恢复外展时间为术后４个月，术后６个月，所有实验组动物的术侧声带均恢复了良好的内收及外展运动，并得到肌电图、肌收缩力及神经肌肉组织化学检查的证实。实验结果表明，同时重建麻痹的声带内收及外展功能是可行且有效的。Fifteen adult dogs were divided into three groups randomly in the experiment.Function rehabilitation of the adduction and abduction after vocal cords paralysis was attempted by selective reinnervation of the laryngeal muscles.Observation showed:onset of recovery of spontaneous adduction was 3 months following surgery, whereas onset of spontaneous abduction was 4 months postoperatively all experimental animals except control group successfully regained synchronous adduction and abduc-tion in 6 months after operation. Electromyography,tension of contraction of laryngeal muscles and histology studies were performed at 6 months postoperatively.The results demonstrated that it was pos-sible and successful to reinnervate the adductor and abductor muscles of the larynx. Moreover,the delay of reinnervation of laryngeal muscles is discussed in the article.
