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 abduction 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 possible 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.
在实验中，15只成年犬被随机分为三组。通过对喉肌进行选择性再支配，尝试恢复声带麻痹后内收和外展的功能康复。观察结果显示：自发内收恢复的起始时间为术后3个月，而自发外展的起始时间为术后4个月，除对照组外，所有实验动物在术后6个月均成功恢复同步内收和外展。术后6个月进行了肌电图、喉肌收缩张力和组织学研究。结果表明，对喉内收肌和外展肌进行再支配是可行且成功的。此外，文章还讨论了喉肌再支配延迟的问题。
