Superior labial artery

The Superior Labial Artery is a facial artery that supplies blood to the upper lip and nose. It is a branch of the Facial Artery, which is itself a branch of the External Carotid Artery.

Anatomy

The Superior Labial Artery arises from the Facial Artery in the vicinity of the angle of the mouth. It then ascends to the medial side of the Nostril and crosses the cheek to the lateral side of the nose. It is larger and more tortuous than its counterpart, the Inferior Labial Artery, and it follows a similar course.

Function

The primary function of the Superior Labial Artery is to supply blood to the upper lip and the nose. It does this by branching off into smaller arteries that reach the various tissues of these areas.

Clinical Significance

The Superior Labial Artery is an important landmark in facial surgeries, particularly those involving the upper lip and nose. Knowledge of its location and course is crucial in avoiding inadvertent injury during these procedures.
