[医] 环杓[软骨]的

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;

Only ansa cervicalis sternothyroid muscular pedicles were transplanted to the paralyzed posterior cricoarytenoid muscles as the control group. 结果术后4个月所有动物均不同程度地恢复了麻痹声带的生理功能。

Conclusion The first-choice treatment of cricoarytenoid joint dislocation is closed reduction, and early reduction is considered as a better approach. 结论环杓关节脱位的首选治疗方法是关节拨动复位，复位越早效果越好。

The arytenoid mobilities and histological changes of cricoarytenoid (CA) joints were observed in 1,2,4,6,8,10,12 months after the injury of recurrent laryngeal nerve (RLN). 为观察喉返神经(RLN)损伤后杓状软骨及环杓关节的变化，将18只犬分为3组。

The nervous reinnervation between the phrenic nerve and the RLN was then realized on purpose to make the phrenic nerve purely innervating the posterior cricoarytenoid muscle (PCA). 对正常、神经切断后立即及神经吻合术后4月环杓后肌进行肌电功能学及形态学检查。

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。
