摘　　要：为探讨延期喉内收及外展肌神经再支配术的时机，选用１５只杂种犬为研究对象，在喉返神经切断后４，６，８，１０及１２个月，分别行膈神经与右喉返神经吻合，并切断内收肌支后，选择性支配右环杓后肌，颈袢主支与喉返神经的内收肌支吻合选择性支配喉内收肌。采用喉镜、神经肌电检查、肌收缩力测定及组织化学检查发现，失神经１０个月内行神经再支配声带可恢复不同程度的内收和外展，同时间声带内收幅度较外展明显，失神经病程越短，内收和外展恢复越好，且在６个月以内行环杓后肌的神经再支配及８个月内行喉内收肌神经再支配效果较好。认为。To investigate time of delayed reinnervated laryngeal muscle, 15 dogs were divided into two groups. The right recurrent laryngeal nerves of 10 dogs in experimental group were cut, and repaired at 4, 6, 8, 10 and 12 months intervals by transposition of the phrinic nerve to the recurrent laryngeal nerve after cutting and suturing the adductor branch to the main branch of ansa cervicalis. The right recurrent laryngeal nerves of 5 dogs in control group were cut, but did not repair. Laryngoscope, electromyography, contractile tension of laryngeal muscle and histologic studies were performed at six months postoperatively. The results showed that fair recovery of adduction and abduction was noted within ten months interval, and the effect of adduction was better than that of abduction. The effect decreased gradually with the denervated time increased. The conclusion demonstrated that delayed reinnervation of laryngeal muscle should be performed within ten months.
