目的：比较不同神经肌蒂环杓后肌移植术治疗声带麻痹的疗效，为临床选择术式提供参考。方法：建立联合性喉麻痹模型，分别用颈袢胸骨舌骨肌肌蒂（简称颈袢组）和副神经胸锁乳突肌肌蒂（简称副神经组）移植于环杓后肌，以恢复声带外展功能。术后４ 个月，分别进行录音、直达喉镜和电视喉动态镜观察声带运动并录像，喉肌电图检查，环杓后肌透射电子显微镜检查和酶组织化学检查并进行电脑图像定量分析。结果：术后颈袢组和副神经组犬吠声均恢复正常，浅麻醉下直达喉镜和动态喉镜检查见双侧声带运动对称，喉肌电图检查均可从环杓后肌上记录到与呼吸同步的动作电位。组织化学及电子显微镜检查两组骨骼肌横纹清晰，神经纤维芽支再生明显，且已与环杓后肌建立了较多的运动终板，肌糖原正常。经统计学处理，两组间无显著性差异（ Ｐ ＞ ０．０５）。对照组肌纤维明显萎缩，肌纤维中几乎无运动终板。结论：神经肌蒂移植术是一种治疗声带麻痹切实有效的方法，颈袢组与副神经组两种术式均能使麻痹喉肌获得有效神经再支配，为临床术式的选择提供实验依据
OBJECTIVE: To compare the curative effect of vasodilator paralysis treated with different neuromuscular and pedicle posterior muscle grafting in order to provide a reference for clinical choice of surgical procedures. Methods: The model of combined laryngopharyngeal paralysis was established. The sternocleidomastoid muscle was transplanted into the posterior circumflex muscle with the sternocleidomastoid muscle of the neck and sternocleidomastoid muscle, respectively Vocal abduction function. At 4 months after operation, they were recorded, and the laryngoscope and video laryngoscope were used to observe vocal motility and video recording, laryngeal electromyography, transmission electron microscopy and enzyme histochemical examination of posterior pars keeper, and computer image quantitative analysis. Results: The bark of dogs in both neck and accessory nerve groups returned to normal after operation, and bilateral vocal cord motion symmetry was seen in direct laryngoscope and dynamic laryngoscopy under light anesthesia. The laryngeal EMG examination could be recorded from the posterior ciliate Action potentials synchronized with respiration. Histochemistry and electron microscopy showed that the skeletal muscle of the two groups had clear striations and regenerated buds of nerve fibers, and more motor end plates had been established with the posterior portion of the ciliate. Muscular glycogen was normal. Statistically, no significant difference between the two groups (P> 0.05). The control group muscle fibers significantly atrophy, muscle fibers almost no motor end plate. Conclusions: Neuromuscular pedicle grafting is an effective and effective method for treatment of vocal cord paralysis. Both surgical methods of neck 袢 group and accessory nerve group can effectively paralyze laryngeal muscle of paralyzed laryngeal muscle, providing experimental evidence for clinical choice
