Vascular variations are common. A cervicofacial anatomical dissection carried out at the anatomy laboratory allowed us to document a rare vascular variation. The facial artery did not give rise to branches that led to the submandibular gland; an artery arising directly from the external carotid artery vascularized the submandibular gland and gave rise to the ascending palatine artery that led to the maxilla. We did not find cases in the literature where an artery emanated directly from the external carotid artery to vascularize the submandibular gland and that gave rise to an ascending palatine artery leading to the maxilla. Knowledge of the variations of the arterial vascularisation of the submandibular gland is important for submandibulectomies and transfers of the gland.
血管变异很常见。在解剖实验室进行的颈面部解剖使我们能够记录一种罕见的血管变异。面动脉没有分支通向颌下腺；直接发自颈外动脉的一支动脉为颌下腺供血，并发出升腭动脉通向上颌骨。我们在文献中没有发现直接发自颈外动脉为颌下腺供血并发出升腭动脉通向上颌骨的动脉的案例。了解颌下腺动脉血供的变异对颌下腺切除术和腺体转移很重要。
