Comprehensive understanding of the variations in the branching of the external carotid artery (ECA) is essential to minimizing vascular complications during cranio-facial and neck surgical procedures. We demonstrate a rare case of unusual branching of ECAs in both carotid triangles and anomalous origin of the left ascending pharyngeal artery (APA) during dissection of embalmed cadaver. The right and left common carotid arteries (CCA) bifurcated at the level of the upper border of the thyroid cartilage. The right superior thyroid artery (STA) originated anterior to the carotid bifurcation (CB), while the left STA originated from the anterior aspect of the left CCA. The right ECA trifurcated into linguofacial trunk, APA, and distal ECA, 15.7 mm from CB. On the left side, lingual artery and APA arose as a short common linguopharyngeal trunk, 1.9 mm from CB. The left facial and occipital arteries originated anteromedially and posteriorly at the same level.
全面了解颈外动脉（ECA）分支的变异对于将颅面和颈部外科手术期间的血管并发症降至最低至关重要。我们在一具防腐尸体的解剖过程中展示了一个罕见病例，双侧颈动脉三角内的ECA出现异常分支，且左咽升动脉（APA）起源异常。左右颈总动脉（CCA）在甲状软骨上缘水平分叉。右侧甲状腺上动脉（STA）起源于颈动脉分叉（CB）前方，而左侧STA起源于左CCA的前侧。右侧ECA在距CB 15.7 mm处分为舌面干、APA和ECA远端。在左侧，舌动脉和APA作为一个短的共同舌咽干发出，距CB 1.9 mm。左侧面动脉和枕动脉在同一水平分别起源于前内侧和后侧。
