目的 进一步研究人喉盖仑（Ｇａｌｅｎ）神经吻合支的解剖构成及分类。方法 用显微神经解剖方法对１００例新鲜人半喉及其喉神经进行系统地研究，对其结果进行统计学分析。结果 人喉盖仑神经吻合支分为上、下两个解剖部分，上部来源于喉上神经内支的末梢支，下部来源于喉返神经后支的末梢支。在此基础上，将其解剖类型分为三型，并认为其出现率既非３０％亦非６０％，而是９１％。结论 来源于喉返神经后支的喉内与喉上神经内支的吻合支才是盖仑神经吻合支，按其解剖构成分三型，Ⅰ型占 ７５％，Ⅱ型占 ２０％，Ⅲ型占 ５％，年龄因素不影响其出现率，左、右侧出现率无显著性差异。盖仑神经吻合支在喉神经感觉传导通路上所发挥的作用，仍有待进一步研究。
Objective To further study the anatomy and classification of human anastomosis branch of Galen. Methods 100 cases of fresh human half throat and its laryngeal nerve were studied systematically by means of microdissection and the results were statistically analyzed. Results The laryngotracheal anastomosis branches were the upper and lower anatomical parts, the upper part came from the branch of the branch of the laryngeal nerve and the lower part came from the branch of the branch of the posterior branch of the recurrent laryngeal nerve. On this basis, the anatomical type is divided into three types, and that the incidence is neither 30% nor 60%, but 91%. Conclusions Anastomotic branches of the Larynx and Laryngeal nerve internal branches originating from the posterior branch of the recurrent laryngeal nerve are galectomy anastomoses. According to their anatomy, the anastomotic branches form 75% of type Ⅰ, 20% of type Ⅱ and Ⅲ Accounting for 5%, age factor does not affect the occurrence rate, the left and right incidence of no significant difference. Galeng nerve anastomosis branch in the laryngeal nerve sensory pathway plays a role that remains to be further studied.
