Angular artery

Angular Artery

The arteries of the face and scalp. (Angular artery labeled at center right.)

The Angular Artery is the terminal part of the Facial Artery, a branch of the External Carotid Artery. It is a significant artery of the face, supplying blood to the upper and lower lips, the side of the nose, and the infraorbital region.

Course

The Angular Artery courses upwards from the Facial Artery, passing over the Zygomaticus muscle and continuing along the side of the nose. It then turns medially to the medial canthus of the eye, where it anastomoses with the Dorsal Nasal Artery, a branch of the Ophthalmic Artery.

Branches

The Angular Artery gives off several branches, including the Superior Labial Artery, Inferior Labial Artery, and Lateral Nasal Branches. These branches supply the upper and lower lips, the side of the nose, and the infraorbital region.

Clinical Significance

Due to its superficial location, the Angular Artery is susceptible to injury, which can result in significant bleeding. It is also an important landmark in facial surgeries and procedures.
