Two Procedures of Nerve Muscle Pedicle Grafting into Posterior Cricoarytenoid Muscle in Dogs 实验犬两种神经肌蒂环杓后肌移植术术式探讨
We observed that contraction of posterior cricoarytenoid muscles cause arytenoid cartilages towards external rocking with external gliding along the cricoarytenoid faucets, leading to vocal processes turning up-posteriorly-externally, departing of bilateral arytenoid cartilages, opening the glottis. 环构后肌收缩使杓状软骨外翻跨动,同时沿环构关书面向外侧滑动,导致声带突向后、外、上方旋转,两侧杓状软骨相互远离,声门开大;
It was suggested that the injury of laryngeal nerve should be considered to be the cause of vocal cord immobility following endotracheal intubation besides cricoarytenoid joint dislocation. 提示该类原因引发的声带固定,除考虑环杓关节脱位外,应想到喉神经损伤的可能。
The nerves of the posterior cricoarytenoid muscle arose from the anterior branch and the interarytenoid ramus which was the one of the subdivisions of the anterior branch. 环杓后肌神经来自前支和前支的分支&杓间肌支,支数多,长度短。
Objective To study the changes of electro-neurogram of the posterior cricoarytenoid muscle in the reinnervation between recurrent laryngeal nerve and phrenic nerve. 目的研究声带外展肌-环杓后肌在喉返神经-膈神经吻合术前、后的神经肌电图表现。
Dynamic Study on Functional Electrical Stimulation of Denervated Posterior Cricoarytenoid Muscle 功能性电刺激失神经环杓后肌的动态研究
Objective: To assess the curative effects of the dislocation of cricoarytenoid joint caused by intubation, indirect laryngoscope ( IL) and direct laryngoscope ( DL) were utilized to the closed reduction of the displaced arytenoid under local anesthesia. 目的:探讨在局麻下经间接喉镜和直接喉镜杓状软骨拨动术对气管插管致环杓关节脱位的疗效。
Contraction of lateral cricoarytenoid muscles cause arytenoid cartilages towards internal rocking, vocal processes to-ward turning down-anteriorly-medially, closing the intermembranous part of glottis. 环杓侧肌收缩使杓状软骨内翻跨动,声带突向前、内、下方旋转,膜间部声门闭合;
Except the cricothyroid muscle, all the laryngeal intrinsic muscles are innervated by the anterior branch of the recurrent laryngeal nerve. In 88% of the cases, the posterior cricoarytenoid muscle is innervated by two nervous pedicle, the others are innervated by a single nervous pedicle. 喉内肌除环甲肌外,均由喉返神经前支支配,其中88%的环杓后肌为喉返神经前支发出单支支配;
CONCLUSION: Continuous functional neuromuscular stimulation on posterior cricoarytenoid muscle can maintain effectively the form and normal structure of posterior cricoarytenoid muscle, and alleviate the fibrosis and atrophy of posterior cricoarytenoid muscle. 结论:对环杓后肌的持续功能性神经肌肉刺激,可以有效的维持环杓后肌的形状和正常的结构,减少环杓后肌的纤维化和萎缩。
Conclusion: The proliferation of dog posterior cricoarytenoid muscle cell remained at high level 4 months after denervation and then slowed down. This suggests that nerve repair should be performed early. 结论:犬环杓后肌失神经后4个月内保持高增殖水平,以后均降低,故神经修复术应力争早期进行。
Change of cricoarytenoid joint after recurrent laryngeal nerve damaged 喉返神经损伤后环杓关节变化的观察
Effect of growth factor on nerve regeneration of the posterior cricoarytenoid muscle in dogs 两种生长因子对犬环杓后肌神经再支配的作用
In order to find a new method to treat paralyzed vocal cord, accessory sternocleidomastoid neuromuscular pedicle flap embeded in denervated posterior cricoarytenoid muscle was studied in dogs. 本文通过应用副神经。胸锁乳突肌蒂瓣植入环杓后肌的动物实验,使失神经支配的环杓后肌重新获得功能,探索治疗喉返神经麻痹的新方法。
Effect observation of different delayed reinnervation of posterior cricoarytenoid muscle 不同延期神经再支配环杓后肌方法的疗效观察
RESULTS: ① Observed generally from the back of posterior cricoarytenoid muscle: the left side of the 1st, the 2nd and the 3rd canines were slightly thinner than the right side. 结果:①犬环杓后肌背面大体观察:第1,2,3只犬左侧肌肉厚度比右侧略薄;
The left posterior cricoarytenoid muscle of the 6th animal showed significant atrophy. 第6只犬左侧环杓后肌明显萎缩,厚度明显变薄。
Objective: To compare the results and effect of different neuromuscular pedicle ( NMP) embeded in posterior cricoarytenoid muscle. 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。
AIM: To establish a model of functional neuromuscular stimulation ( FNS) in canine larynx to simulate clinical injury of larynx and to observe histological changes of posterior cricoarytenoid muscle under the effect of functional neuromuscular stimulation. 目的:建立犬喉功能性神经肌肉刺激的模型,模拟临床喉损伤,在功能性神经肌肉刺激作用下,观察环杓后肌的组织学变化。
Enzyme-Histochemistry and Structure Studies of Posterior Cricoarytenoid Muscle after Denervation 切断单侧喉返神经后健侧环杓后肌结构与酶组化变化的研究
Experimental Study on Excitability of Posterior Cricoarytenoid Muscle After Denervation and Reinnervation 环杓后肌失神经及神经再支配后兴奋性的研究
Objective: To observe cricoarytenoid ( CA) joint affecting prognosis of delay reinnervation of laryngeal muscles after recurrent laryngeal nerve paralysis. 目的:观察环杓关节在延期喉内肌神经再支配后的变化及对杓状软骨运动的影响。
Lateral cricoarytenoid muscle, posterior cricoarytenoid one, thyroarytenoid and interarytenoid ones were often invaded. 环杓侧肌、环杓后肌、甲杓间和杓间肌经常受侵;
Results CT findings of recurrent laryngeal nerve paralysis included: oblique of aryepiglottic fold, dislocation of arytenoids cartilage and cricoarytenoid joint, dilation and relaxation of piriform sinus for 27 cases ( 84.4%); 结果喉返神经麻痹后,CT检查可出现一系列相应表现:杓会厌皱襞、杓状软骨及环杓关节前内侧移位,同侧梨状窝扩张、松弛27例(84.4%);
