Dorsal Nasal Vein

Description

Running along the dorsum of the nose, the dorsal nasal vein is traced superficially over the nasal bones and upper lateral cartilages, just inferior to the glabella and medial to the medial canthus. It courses superiorly to communicate with the angular vein at the side of the nose and with the ophthalmic venous system near the orbit, in close proximity to the lacrimal apparatus. Bony context from the skull is visible, including the orbital rims, piriform aperture, and maxillary dentition, with color coding that distinguishes facial veins from adjacent arteries. Relationships are easy to read. Facial venous anatomy in this region matters because the dorsal nasal vein forms part of the pathway between the superficial face and the orbit through connections with the angular and superior ophthalmic veins. That anastomotic route underlies the classic clinical concern for spread of infection from the nasal dorsum or medial canthus to the orbit and cavernous sinus, including septic cavernous sinus thrombosis and orbital cellulitis. For procedural teaching, the vein’s position relative to the nasal bridge and medial orbital margin helps orient safe planes during dorsal nasal injections, rhinoplasty exposure, and lacrimal surgery where bruising and hematoma track along predictable venous channels. Faculty can drop this figure directly into head and neck anatomy lectures, ophthalmology modules on orbital venous drainage, or ENT teaching on nasal soft tissue planes, with the skull overlay serving as a reliable landmark map for learners. It also fits well in clinical anatomy atlases, patient safety materials about facial “danger triangle” infections, and surgical texts discussing periorbital ecchymosis patterns.
