Horizontal Labiomental Artery

Description

Shown in right lateral view, the bony skull and dentition provide landmarks for a fine-caliber horizontal labiomental artery coursing within the soft-tissue corridor of the lower lip and chin region. The vessel runs anteriorly and slightly inferiorly across the labiomental groove, typically arising from the facial artery system and anastomosing with the inferior labial and mental arterial territories near the mental foramen. Red arterial channels and blue venous counterparts trace across the face and cranium, with orbital vascular networks visible deep to the superolateral and inferomedial margins of the bony orbit. Small space, small vessel. Clinical value centers on where this artery sits relative to the mandibular body, the mental foramen, and the perioral tissues commonly traversed in injection and incision. Labiomental and inferior labial branches are implicated in hematoma and tissue ischemia after filler placement in the chin or lower lip, and they can complicate local flap planning during reconstruction of lower-lip defects. The lateral perspective also supports teaching of anastomoses between facial artery branches and the mental region, a frequent source of brisk bleeding during laceration repair along the labiomental crease. Use this artwork for head and neck anatomy curricula, dental and oral and maxillofacial surgery teaching files, and procedural guides covering perioral injections, mental nerve blocks, and lower-lip reconstruction planning. It also fits atlases or journal figures discussing facial artery branching patterns, vascular danger zones in aesthetic medicine, or surgical approaches near the mental foramen.
