面神经面神经管段、舌咽神经和迷走神经各分支在神经干内定位的初步观察

Preliminary Observation on the Localization of Branches of Facial Nerves in the Facial Canal and Branches of Glossopharyngeal and Vagus Nerves in their Nervous Trunk

面神经面神经管段与舌咽神经用12例头颈部尸体材料,迷走神经用46例尸体材料研究各神经分支在该神经干内的位置以及与其他分支的相互位置关系。为人体解剖学提供新的理论知识,也为临床显微外科学提供了有用的参考资料。

Twelve cases of human head and neck were used to observe the facial and the glossopharyngeal nerves. 46 cases of corpse were applied to observe the vagus nerves. At first, the branches of the nerves were dissected and then each branch was centripetally separated by the tweezers under the stereomicroscope. The location of each branch and the relationship among branches in the nervous trunk was observed and recorded simultaneously. Tne location of each branch in the nervous trunk was stable. No obvious difference in the lica tion of adult and infant was found. Thispager contributes some favourable anatomic data for the clinical application.
