Notes

The superior labial vein (vena labialis superior) is a vein that drains the upper lip. It is a tributary of the facial vein.

Anatomy

The superior labial vein is located in the upper lip and is responsible for draining blood from this region. It runs parallel to the superior labial artery, which supplies blood to the same area. The vein collects blood from the upper lip and transports it to the facial vein, which eventually drains into the internal jugular vein.

Function

The primary function of the superior labial vein is to drain deoxygenated blood from the upper lip. This is part of the larger circulatory system that ensures blood is returned to the heart for reoxygenation.

Clinical significance

Issues with the superior labial vein can lead to various medical conditions, such as varicose veins or venous insufficiency. In some cases, trauma or surgical procedures involving the upper lip may affect this vein, leading to complications such as hematoma or infection.
