Transverse Facial Artery, Anterior View

Description

Centered on an anterior, skinless head and upper neck, the transverse facial artery is traced as it courses laterally across the cheek, running superficial to the masseter and parallel to the zygomatic arch. Its origin from the superficial temporal artery is implied in the preauricular region, just superior to the parotid gland area and anterior to the external acoustic meatus, with small branches extending medially toward the buccal region. Surrounding landmarks include the orbicularis oculi at the orbital margin, the zygomaticus major and minor descending inferomedially from the zygomatic bone toward the modiolus, and the orbicularis oris encircling the oral fissure. Inferiorly, the sternocleidomastoid anchors the anterior neck anatomy and frames the lateral cervical region. Facial arterial anatomy matters most when the tissue planes are disrupted. During facelift (rhytidectomy), parotid surgery, and repair of zygomaticomaxillary complex fractures, the transverse facial artery can be encountered within the superficial musculoaponeurotic system and injured, producing brisk bleeding and postoperative hematoma. This vessel also provides a key collateral pathway to the facial artery territory, a point worth emphasizing when teaching flap perfusion, cheek laceration repair, or interpretation of angiographic anatomy in the preauricular and malar regions. Small vessel, big consequence. Use this artwork for head and neck anatomy teaching blocks, surgical anatomy chapters on the parotidomasseteric region and SMAS plane, and clinical skills materials covering facial lacerations, hemostasis, and safe injection zones for fillers near the zygomatic arch. It also reads well as a labeled plate for dental and maxillofacial training where masseter surface landmarks guide incisions and dissections.
