Superior Labial Artery

Arteria labialis superior

The superior labial artery arises from the facial artery as it passes the angle of the mouth. It is much larger and more tortuous than the inferior labial artery.


The superior labial artery passes anterosuperiorly, coursing along the margin of the upper lip, between the orbicularis oris and the mucous membrane of the lip.


The superior labial artery provides a nasal septal branch to the nose. Additionally, when the facial artery is deficient, the superior labial artery may provide arterial supply to the nose via alar branches (Standring, 2016).

Supplied Structures

The superior labial artery supplies the superior labial glands, overlying mucosa, upper part of orbicularis oris, zygomaticus major and minor, depressor septi nasi, levator anguli oris, levator labii superioris alaeque nasi, levator labii superioris, nasalis, and risorius, and nasal septum (Netter, 2011).
