尽管喉部神经生理学的知识已有进一步的了解,又采用显微外科手术,但治疗双侧声带麻痹仍有困难。早在1924年,作者首次描述了改良的隔神经移植手术。用14只狗进行实验,将膈神经裂开,然后用一条游离神经,一端缝在裂开膈神经的内半部,一端缝到环杓后肌中,结果5只狗在吸气时外展运动良好。本文报道用上述手术方法治疗4例双侧声带 Despite further knowledge of laryngeal neurophysiology and the use of microsurgery, there remains difficulty in treating bilateral vocal cord paralysis. As early as 1924, the author described for the first time a modified transendothelial nerve transplant. In 14 dogs, the phrenic nerve was dehiscted, and then a free nerve was used, one end of which was stitched into the inner half of the phrenic nerve and the other was sewn to the posterior ciliate of the scaphic aponeurosis. As a result, 5 dogs were outreach during inspiration Good exercise. This article reports the use of the above surgical treatment of 4 cases of bilateral vocal cords
