Scalp Arteries, Anterior View

Description

Across the anterior scalp and forehead, the superficial temporal arteries ascend anterior to the auricles and divide into frontal and parietal branches that course superiorly within the scalp, while the supraorbital and supratrochlear arteries emerge at the superior orbital margin to supply the midline forehead. Laterally, the zygomatico-orbital branch may be appreciated crossing toward the lateral orbital region, with anastomoses spreading across the frontotemporal scalp. Superficial facial musculature provides context, including the frontalis overlying the forehead, orbicularis oculi encircling the palpebral fissures, zygomaticus muscles tracking inferolaterally from the zygomatic bone, masseter over the mandibular ramus, and a prominent sternocleidomastoid descending inferolaterally in the neck. Veins accompany the arterial pathways in the superficial fascia. Orientation is anterior, with vessels mapped relative to the frontal bone, temporal region, and superior orbital rim. This anterior mapping matters because the scalp’s vascular territory is predictable and clinically unforgiving, lacerations in the dense connective tissue layer of the scalp can bleed briskly, and the anastomotic network permits collateral flow after proximal injury or ligation. Palpation of the superficial temporal artery just anterior to the tragus remains a practical bedside landmark, and its involvement in temporal arteritis (giant cell arteritis) links scalp vessel anatomy directly to headache evaluation and risk of visual loss. Surgeons planning coronal or temporal incisions, and injectors placing local anesthetic blocks of the supraorbital and supratrochlear nerves, benefit from seeing the arteries in relation to the orbital rim and frontalis. Common uses include head and neck anatomy teaching in medical and dental curricula, operative atlases for facelift and temporal approaches, and patient-facing educational materials explaining scalp laceration bleeding or temporal arteritis evaluation. It also suits emergency medicine and ENT training modules that emphasize surface landmarks and predictable arterial courses. Anatomical accuracy verified by SciePro's Medical Advisory Board.
