The veins of the face, showing the superior labial vein (labeled as facial vein)

The Superior Labial Vein is a vein that drains the upper lip and the region of the face superior to it. It is a tributary of the Facial Vein, which eventually drains into the Internal Jugular Vein.

Anatomy

The superior labial vein begins at the medial angle of the eye, where it is continuous with the Angular Vein. It runs downward and laterally, closely accompanying the Facial Artery on the face. It receives tributaries from the nose and upper lip, and at the angle of the mouth, it communicates with the Inferior Labial Vein and then continues as the facial vein.

Clinical Significance

The superior labial vein, like other veins of the face, is clinically significant due to its anastomoses with the Cavernous Sinus through the Ophthalmic Veins. This connection can potentially allow infections from the face to spread to the brain, leading to serious conditions such as Cavernous Sinus Thrombosis.
