We report a unique variation in the origin and branches of both the left and right external carotid artery (ECA) found during the dissection of a human cadaver. Knowledge of the possible anatomical variations of the ECA is especially important in facio-maxillary and neck surgeries. Surgeons need to be aware of the possibility of encountering such variations, as they may lead to difficulties in differentiating between the external and internal carotid arteries, and in identifying the branches and origins. This knowledge is also important for radiologists in the image interpretation of the face and neck regions.
我们报道了一例在解剖人体尸体时发现的左、右颈外动脉（ECA）起源和分支的独特变异。了解 ECA 的可能解剖变异在面颈部手术中尤为重要。外科医生需要意识到可能会遇到这种变异，因为这可能导致在区分颈外和颈内动脉以及识别分支和起源时出现困难。对于在面颈部区域进行图像解读的放射科医生来说，这方面的知识也很重要。
