神经肌蒂移植术治疗声带麻痹的对比实验研究

目的；比较不同神经肌蒂环榴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，环榴后肌透射电子显射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

A comparative study of different neuromuscular pedicle embededin posterior cricoarytenoid muscle

Objective:To compare the results and effect of different neuromuscular pedicle (NMP) embeded in posterior cricoarytenoid muscle.Method:In 22 dogs,combined vocal cord paralysis models were made. The first group (10 dogs) were embeded by sternohyoid muscle pedicle of ansa cervicalis, the second (10 dogs), accessory sternocleidomastoid neuromuscular pedicle, the third (2 dogs), control group. Result:Evaluation was possible in 19 dogs. Reinnervation of the left posterior cricoarytenoid muscle occurred in 17 dogs following NMP. Return of spontaneous abduction in the operated side with NMP was noted after 4 months postoperatively. There was little difference between the two NMP groups.Conclusion:NMP was successful to reinnervate the posterior cricoarytenoid muscle.
