将８只狗的右侧喉返神经及其内收支切断，再分别将其中４只狗的右侧颈交感神经干和２只狗的右侧舌下神经袢切断后，各将其近侧端和已切断的喉返神经的远侧端吻合，其余２只狗作为失神经支配的对照组。分别于术前、术后即刻及术后４个月行声门照像、肌电图观察，最后行环杓后肌肉眼及组织化学观察。实验结果证明：采用两种神经修复喉返神经均可部份恢复环杓后肌功能，论证了用颈交感神经干修复的机理及各种神经修复法的优缺点，为今后进一步的研究和临床应用提供理论依据。
The right recurrent laryngeal nerve and their adductor branches of 8 dogs were cut off, and then the right cervical sympathetic trunk of 4 dogs and the right hypoglossal nerve of 2 dogs were cut off, The distal end of the recurrent laryngeal nerve that had been severed was anastomosed with the remaining two dogs as the denervated control. The glottic and electromyogram were performed before operation, immediately after operation and 4 months after operation respectively. Finally, the cochlear muscle and the histochemistry were observed. Experimental results show that: the use of two kinds of nerves to repair the recurrent laryngeal nerve can be partially restored after the function of the ciliate, demonstrate the mechanism of cervical sympathetic trunk repair and the advantages and disadvantages of various nerve repair methods for future research and clinical Application provides a theoretical basis.
