Anatomical terminology]

The supraorbital artery is a branch of the ophthalmic artery. It passes anteriorly within the orbit to exit the orbit through the supraorbital foramen or notch alongside the supraorbital nerve, splitting into two terminal branches which go on to form anastomoses with arteries of the head.

Structure

Origin

The supraorbital artery arises from the ophthalmic artery.[1][2]

Course and relations

It travels anteriorly in the orbit by passing superior to the eye and medial to the superior rectus and levator palpebrae superioris.[citation needed] It then joins the supraorbital nerve to jointly pass between the periosteum of the roof of the orbit and the levator palpebrae superioris towards the supraorbital foramen or notch.[3] After passing through the supraorbital foramen or notch, it often splits into a superficial branch and a deep branch.[1]

Distribution

The supraorbital artery contributes arterial supply to: the

levator palpebrae muscles, periorbita,[1] the diploë of the frontal bone, frontal sinus, upper eyelid,[citation needed] and the skin and musculature of the forehead and scalp.[1]

Anastomoses

Its terminal branches anastomose with the supratrochlear artery, frontal branch of superficial temporal artery, and the contralateral supraorbital artery.[1]

Variation

This artery may be absent in 10% to 20% of individuals.[4]
