In preparation for the donor and recipient facial vascularized composite allotransplant (VCA), the marginal mandibular nerve branch should be identified and co-apted to the recipient's nerve to allow for re-innervation. We describe a method to identify the marginal mandibular branch of the facial nerve in facial VCA donors and recipients. Through cadaver dissections, the posterior facial vein was traced posteriorly to identify the marginal mandibular branch of the facial nerve. In cases where we were unable to use this relationship, we found the posterior facial venous system to be diminutive. This technique is useful for finding the marginal mandibular branch when dissecting anterograde to the parotid gland.
在准备供体和受体面部血管化复合组织异体移植（VCA）时，应识别下颌缘神经分支并将其与受体神经吻合，以实现再支配。我们描述一种在面部VCA供体和受体中识别面神经下颌缘分支的方法。通过尸体解剖，向后追踪面后静脉以识别面神经下颌缘分支。在无法利用这种关系的情况下，我们发现面后静脉系统较小。该技术在向腮腺进行顺行解剖时有助于找到下颌缘分支。
