A Lateral perspective of the Nasal Septal Branch of the Superior Labial Artery of a human male

Description

From a lateral facial perspective, the superior labial artery is seen coursing within the upper lip as a branch of the facial artery, giving off the nasal septal branch that turns superiorly to ascend along the mobile anterior nasal septum. Its path lies anterior to the maxilla and inferior to the nasal cartilages, tracking medially toward the columella and vestibule rather than the lateral nasal wall. Surrounding vasculature over the midface and periorbital region remains visible in context, with dentition and cranial bony landmarks providing orientation. Clinical relevance is highest where the anterior septum concentrates anastomoses between external carotid and internal carotid systems, the vascular substrate of Kiesselbach’s area and a common source of anterior epistaxis. Ligation or embolization planning often hinges on recognizing whether bleeding likely arises from branches of the superior labial and sphenopalatine arteries versus the anterior ethmoidal artery, and this lateral relationship helps clarify the external carotid contribution. Small vessel. Big bleed. Use this asset for ENT teaching on epistaxis anatomy, maxillofacial and plastic surgery references for columellar and septal approaches, and medical publishing that needs a clean depiction of facial vasculature in relation to skull and dental landmarks for orientation.
