摘要
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。
A comparative study of four methods of laryngeal muscle reinnervation in dogs is presented. Twenty eight cases were divided into four groups to undergo main branch and branch of ansa cervicalis nerve anastomosis, and nerves implantation and neuromuscular pedicles transfer respectively for restoration of vocal cord adduction on left sides. The results showed that the four procedures seemed to induce effective reinnervation of adductor muscles. But the main branch of ansa cervicalis nerve suture was superior to the other methods among which little difference was noted in the functional recovery, electrophysiological activity and muscle strength. It demonstrated that main branch of ansa nerve suture was the best procedure for treatment of unilateral vocal cord paralysis among the four methods.
