Anatomical Structure and Location of the Zygomatic Branch of the Lacrimal Artery

Description

Centered on the lateral orbit of an adult male skull, the lacrimal artery is traced from the ophthalmic artery along the superior aspect of the globe toward the lacrimal gland, then followed as its zygomatic branch turns laterally toward the zygomatic bone. Near the frontozygomatic region the vessel runs close to the lateral orbital wall, approaching small foramina at the zygomaticoorbital surface before leaving the orbit to anastomose on the face. Surrounding osseous landmarks include the orbital rim, zygomatic bone, maxilla, nasal bones, and adjacent cranial vault, with cervical vertebrae continuing inferiorly in the same plate. Small veins and slender nerve trajectories are suggested in parallel, consistent with orbital neurovascular topography. Tight anatomy. Attention to the zygomatic branch matters when you need to teach or plan how the lacrimal artery contributes to periorbital and malar perfusion through transosseous exits, a point that explains why bleeding can track unexpectedly during lateral orbitotomy, zygomaticomaxillary complex fracture repair, or deep dissection near the frontozygomatic suture. The course also provides a practical map for understanding collateral flow between the ophthalmic artery system and superficial facial vessels, and why embolization or traumatic injury in the orbit can have cutaneous consequences over the cheek and temple. Use this artwork in head and neck anatomy lectures that cover the ophthalmic artery branches, in maxillofacial surgery and oculoplastics teaching files for lateral orbital approaches, or in a publisher’s atlas plate discussing orbital foramina and arterial anastomoses around the zygoma. It also reads well for exam questions that ask learners to link bony openings to named vessels. Anatomical accuracy verified by SciePro's Medical Advisory Board.
