本文使用21侧颌面部材料,其中成人11侧,初生儿10侧;左11侧;右10侧。首先解剖舌下神经及其分支,以后在手术显著镜下对舌下神经分支做向中性分离,同时观察各分支在舌下神经干内的位置及其相互关系,本研究为面神经-舌下神经吻合术提供舌下神经干内显微外科解剖学的有关资料,也填补了舌下神经解剖学的理论知识。舌下神经分支的形式是恒定的,一般有六种主要分支。为观测这六种分支在神经干内位置,我们将舌下神经干分为四个观察单位进行观察。在(一)内有2或3个神经束,居外
This article uses 21 maxillofacial materials, including 11 adult side, 10 newborns; left 11 side; right 10 side. First of all, the hypoglossal nerve and its branches were dissected. Afterwards, the sublingual nerve branches were separated to the neutral under the significant operation microscope. At the same time, the location of each branch in the hypoglossal nerve trunk and its relationship were observed. Nerve anastomosis provides information about the anatomy of the hypoglossal trunk in microsurgery and also fills in the theoretical knowledge of the hypoglossal nerve anatomy. The form of the hypoglossal nerve branches is constant and there are generally six main branches. To observe the location of these six branches within the nerve trunk, we divided the hypoglossal trunk into four observation units for observation. In (a) there are 2 or 3 nerve bundles, living outside
