The facial artery is the main artery of the face and variations in its origin and its branching pattern have been documented. We report herein multiple facial artery branch variations in the face. A large posterior (premasseteric) branch originated from the left facial artery and coursed upwards behind the main trunk of the facial artery. This artery presented with a straight course and was closely related to the anterior border of the masseter. The branch then terminated by supplying the adjacent connective tissue below the parotid duct. It was also observed that the facial artery was very thick and tortuous and terminated as the superior labial artery. Knowledge of this variation is of great clinical significance in facial operations, especially for maxillofacial surgeons and plastic surgeons, because it forms the anatomical basis for the facial artery musculo-mucosal flap.
面动脉是面部的主要动脉，其起源和分支模式的变异已有文献记载。我们在此报告面部面动脉的多种分支变异情况。一条粗大的后（咬肌前）支起源于左侧面动脉，在面动脉主干后方向上走行。该动脉走行笔直，与咬肌前缘关系密切。然后该分支通过供应腮腺导管下方的相邻结缔组织而终末。还观察到面动脉非常粗大且迂曲，并以唇上动脉终末。了解这种变异对面部手术具有重要的临床意义，尤其对于颌面外科医生和整形外科医生而言，因为它构成了面动脉肌黏膜瓣的解剖学基础。
