为了比较几种颈袢修复声带内收肌功能的方法的效果，选用犬２８只，随机分成主支吻合组、分支吻合组、神经植入组及肌蒂埋植组。建立单侧声带麻痹模型后即刻分别作颈袢主支或分支与喉返神经内收肌支吻合，颈袢主支的亚分支或其肌蒂植入声带内收肌中。术后６个月作喉镜、电生理学、肌力及组织形态学检查。发现四种修复术均能使声带内收肌获得有效的再神经支配，但在声带内收功能恢复程度，电生理学参数和肌收缩力上，颈袢主支吻合术均明显优于分支吻合术、神经植入术及肌蒂植入术，并得到形态学检查的证实。提示，颈袢支配喉内收肌应首选主支吻合术。
In order to compare the effects of several methods of neck vocal cord retraction on adductor muscular function, 28 dogs were randomly divided into primary anastomosis group, branch anastomosis group, nerve implants group and muscle implants group. Immediately after unilateral vocal cord paralysis model was established, the main branch or branch of the neck was anastomosed with the adductor muscular branch of the recurrent laryngeal nerve. The sub-branches of the main branch of the neck 或 or its muscle pedicles were implanted into the adductor adductor. 6 months after laryngoscopy, electrophysiology, muscle strength and histological examination. It was found that all the four kinds of repair can make effective re-nerve innervation of vocal cord. However, in terms of the degree of recovery of vocal cord adduction, electrophysiological parameters and muscle contractility, the main anastomosis of neck and neck was significantly better than that of branch and anastomosis , Nerve implantation and muscle pedicle implantation, and confirmed by morphological examination. Tip, neck dorsal adductor should dominate the main adductor anastomosis.
