In medical literature, there are few studies provided a precise and detailed description of the facial nerve rami and its branches.
Identify several practical anatomic landmarks related to the facial nerve main trunk and its rami.
A descriptive study, 30 cadavers in the anatomy department of UPNT from October 2012 to April 2015.
The average distance from the mandibular angle to the division of the facial nerve is 40.8 mm, and is 86.6% from range 36 - 50 mm. There is 86.7% case in which the facial nerve is in the lateral of the retromandibular vein, and there is a significant difference about both sides. Eighty percent of the case has the superior and inferior ramus in the lateral to the retromandibular vein. There are 2 cases in which the superior ramus makes the circle of the vein. Eighty percent of the facial nerve is in the lateral to the external carotid artery.
The distance from the mandibular to the division of the facial nerve is longer. The relationship between the superior/inferior ramus and the retromandibular vein maybe not the same in both sides. In some cases, it makes the circle of the vein to cause some complication in the parotid gland surgery.
在医学文献中，很少有研究对面神经分支及其分支进行精确而详细的描述。
确定与面神经主干及其分支相关的几个实用解剖标志。
一项描述性研究，于2012年10月至2015年4月在UPNT解剖学系对30具尸体进行研究。
下颌角至面神经分支的平均距离为40.8mm，36 - 50mm范围的占86.6%。86.7%的病例中面神经位于下颌后静脉外侧，两侧存在显著差异。80%的病例中上下分支位于下颌后静脉外侧。有2例上支环绕静脉。80%的面神经位于颈外动脉外侧。
下颌至面神经分支的距离较长。上下分支与下颌后静脉的关系两侧可能不同。在某些情况下，它会环绕静脉，在腮腺手术中引起一些并发症。
