Transverse Facial Artery

Description

Running anterior to the parotid region, the transverse facial artery arises from the superficial temporal artery and courses horizontally across the masseter, inferior to the zygomatic arch and superior to the parotid duct. From this left lateral view of the male head and neck, the vessel is seen giving small rami toward the parotid gland, the buccal region, and the orbicularis oris, with anastomotic connections to the facial artery as it ascends toward the lateral nose. Bony landmarks of the skull and mandible provide orientation, while the cervical vertebrae sit posterior to the carotid sheath structures in the neck. Red arterial pathways and blue venous channels outline the broader vascular map, including the external carotid system and adjacent jugular drainage. Attention to the transverse facial artery matters when planning incisions and dissections in the preauricular and midface region, because it crosses superficially over the masseter where it can be encountered in rhytidectomy (facelift) flaps and parotid surgery. Injury here can produce brisk bleeding and postoperative hematoma, and the artery’s anastomoses with facial and infraorbital branches explain why ligation of a single vessel may not fully control midface hemorrhage. Small vessel, real consequence. Medical educators can place this plate in head and neck anatomy blocks to teach external carotid branching patterns and surface relationships to the zygomatic arch, parotid gland, and masseter. It also supports surgical texts and CME materials on facial soft-tissue elevation, parotidectomy, and management of midface lacerations where the transverse facial artery and its arteriolar network are common sources of bleeding.
