作者们采用Tucker介绍的神经肌蒂移植法,于狗单侧声带麻痹后的不同时期,将神经肌蒂移植于环构后肌,以确定移植最适宜的时间。本文报告实验结果,并对恢复声带外展的机制提出了与Tucker不同的看法。用狗10只,静脉麻醉下按Tucker法取舌下神经袢至胸骨甲状肌肌蒂5mm大小;于甲状软骨角分离咽下缩肌,暴露环杓后肌,用7-0丝线将肌蒂缝于该肌。4狗是在7～8月前已切断或结扎迷走神经干和喉上神经,2狗是在2月前失神经支配,4狗于移植术的同时切断喉返神经。均经直达喉镜检查,有些行肌电图检查证实声带麻痹。术后2月检查声带外展恢复情况。杀狗4只,其余每月检查一次,用电影、磁带录像记录声带运动情况。为刺激其最大用力呼吸,有的吸
Using the neuromuscular pedicle graft method introduced by Tucker, the authors transplanted neuromuscular pedicles to the posterior circumflex muscle at different stages of unilateral vocal cord paralysis in dogs to determine the most appropriate time for transplant. This article reports experimental results and presents a different view of Tucker’s mechanism for resuming vocal cord outreach. 10 dogs, intravenous anesthesia according to Tucker method to take hypoglossal nerve 袢 to the sternum thyroid muscle pedicle 5mm size; in the thyroid cartilage corner of the swallow systolic muscle, exposed after the ring scoop muscle, with 7-0 silk will be muscle pedicle The muscle. 4 dogs in the 7 to August has been cut off or ligation of the vagus nerve and laryngeal nerve, 2 dogs are denervated 2 months ago, 4 dogs at the same time cut off the recurrent laryngeal nerve. Through direct laryngoscopy, some electromyography confirmed vocal cord paralysis. Postoperative February examination of vocal cord outreach recovery. Kill the dog 4, the rest once a month check, with a movie, tape video recording vocal movement. In order to stimulate their maximum force breathing, some suction
