Angular Artery, Anterior View

Description

Running superiorly along the lateral aspect of the nose, the angular artery appears as the terminal continuation of the facial artery at the medial canthus, where it lies adjacent to the angular vein and deep to the superficial fascia. From an anterior position in a male head and neck, you would also expect the facial artery crossing the inferior border of the mandible anterior to the masseter, then coursing obliquely toward the nasolabial fold with labial branches to the orbicularis oris and nasal branches toward the dorsum nasi. Surrounding soft tissue landmarks include the orbicularis oculi encircling the palpebral fissure, the zygomaticus major and minor running inferomedially toward the modiolus, and the levator labii superioris alaeque nasi paralleling the lateral nasal wall. That distal segment matters because it sits at the crossroads of external carotid and internal carotid circulation, with frequent anastomoses between the angular artery and dorsal nasal branches of the ophthalmic artery. A small vessel, big consequences. Injections of dermal fillers in the nasolabial fold, alar base, or tear trough can enter the angular artery and retrograde embolize into the ophthalmic circulation, a recognized mechanism for retinal ischemia and sudden vision loss, so understanding its superficial course relative to the medial palpebral ligament and nasal sidewall is not academic. Facial surgeons and dermatologic injectors use this view to plan incisions and injections around the medial canthus, manage epistaxis-related facial branch bleeding, and interpret flap perfusion in nasolabial and paramedian forehead reconstruction. It also fits cleanly into head and neck anatomy teaching, ophthalmic vascular anastomoses, and procedural safety figures for textbooks, informed consent documents, and CME slide decks.
