Arteria angularis

Origin

The angular artery is the terminal portion of the facial artery. However, if the facial artery is deficient, the angular artery is replaced by either the nasal branch of the ophthalmic artery, the transverse facial artery, or the maxillary artery (Tubbs et al, 2016).

Course

The angular artery continues to ascend on the face to the medial angle of the orbit, within the fibers of the levator nasolabialis muscle. The angular artery is usually small, and its course is variable.

Branches

There are no named branches.

Supplied Structures

The angular artery provides arterial supply to the lacrimal sac, orbicularis oculi muscle, and lower eyelid. Additionally, it anastomosis with the external nasal artery (or dorsal nasal branch of the ophthalmic artery).
