替代神经吻合法治疗喉返神经麻痹的解剖学研究

Anatomical study on anastomose of surrogate nerves for treatinent of paralysis of recurrent laryngeal nerve

对３０例喉神经、膈神经、颈袢的解剖观测及利用图象分析仪二维重建技术对相关神经的截面积、纤维数量的测量比较分析，结合有关实验研究资料，设计了在甲状软骨板后下方开窗，于甲杓肌神经起点处切断该神经，用颈袢主支与甲杓肌神经吻合，用膈神经与喉下神经吻合，同时重建声带的内收和外展功能，并探讨了其解剖和生理学基础，认为此手术方法治疗喉返神经麻痹是较理想和可行的。

Laryngeal,phrenic nerves and cercical loops of 30 cases were observed ,and their relative area and fiber number of each nerve were counted and compared by means of image analysis technique.We designed a new operation method after consum some date. That was to open the posterior inferior part of the thyroid cartilage lamina,to cut the thyreoarytenoid nerve at its begining,to make the anastomoses of cervical loop trunk with the nerve of thyeoarytenoid muscle,and phrenic nerve with inferior laryngeal nerve. The abducent and adducent abilities of the vocal cord were reconstructed in the sarne time. Author discussed physiological and anatomical bases in this paper. These indicated that this can be an ideal and practicable method to cure the paralysis of laryngeal muscules.
