Lateral Nasal Vein, Anterior View

Description

Running along the lateral aspect of the external nose, the lateral nasal vein is shown superficially over the nasal bone and upper lateral nasal cartilage, draining the skin and subcutaneous tissues toward the angular vein near the medial canthus. Superiorly it approaches the venous plexus at the root of the nose, while inferiorly it communicates with tributaries over the nasal ala. Adjacent facial landmarks include the orbit, piriform aperture, maxilla, and anterior nasal spine, with the venous channel mapped in blue against the underlying skull. Clinically, this vein matters because it sits within the facial venous network that connects the facial vein to the angular vein and then to the superior ophthalmic vein, a pathway relevant to the spread of infection from the nose toward the orbit and cavernous sinus. Small as it is, it becomes conspicuous during nasal trauma, rhinoplasty dissection, and laceration repair where venous bleeding can obscure the operative field and where precise knowledge of the medial canthal drainage pattern helps avoid postoperative hematoma. A key teaching point is its relationship to the angular vein at the superomedial orbit. Short and direct. Educators can place this anterior facial vascular view into head and neck anatomy curricula, surface anatomy labs, and procedural teaching on nasal packing, local flap planning, and repair of nasal sidewall wounds. It also fits cleanly into ENT, maxillofacial, and ophthalmology publications that need an accurate map of superficial facial venous drainage on a skeletal reference.
