Frontal Branch Of The Superficial Temporal Artery

Description

Arising from the superficial temporal artery anterior to the auricle, the frontal branch ascends within the superficial fascia of the temporal region and then sweeps anterosuperiorly across the temple toward the lateral forehead. Along its course it lies superficial to the temporalis muscle and deep to the thin scalp tissues, crossing the zygomatic arch region before distributing over the frontal bone; small arteriolar offshoots are suggested as it approaches the frontoparietal scalp. Underlying skeletal landmarks such as the cranium, zygomatic arch, mandible, and upper cervical vertebrae provide positional reference, while superficial veins track in parallel with the arterial path and fine peripheral nerves are indicated in the same corridor. Frontal branch anatomy matters because it is the dominant arterial supply encountered during temporal and forehead incisions, and it sits in the same operative field as the temporal branch of the facial nerve as that nerve crosses the zygomatic arch toward frontalis. Injury can produce brisk scalp bleeding that is difficult to tamponade due to dense galeal attachments, and iatrogenic compromise of the vessel can complicate forehead flap design or compromise healing in hairline and brow procedures. Palpation of the superficial temporal artery and its frontal branch also guides bedside localization for temporal arteritis assessment and for selecting targets during endovascular planning in external carotid territory. Plastic surgery and ENT teaching sessions on brow lift approaches, temporal artery biopsy planning, and scalp laceration repair will benefit from this head and upper torso model that overlays arteries, veins, and nerves onto bony anatomy for quick orientation. Medical publishers can pair it with text on the external carotid system, transverse facial artery relationships, and surface landmarks in the male temporal region.
