Structure
Origin
The dorsal nasal artery is one of the two terminal branches of the ophthalmic artery (the other being the supratrochlear artery).[1] It arises in the superomedial orbit.[2]
Course and relations
It passes anteriorlyScript error: No such module "Unsubst". to exit the orbit between the trochlea (superiorlyScript error: No such module "Unsubst".), the medial palpebral ligament (inferiorlyScript error: No such module "Unsubst".).[1] It gives a branch to the lacrimal sac before bifurcating into two branches: one branch anastomoses with the terminal (angular) part of the facial artery[1] and is important for the blood supply of the face;Script error: No such module "Unsubst". the other travels along the dorsum of the nose to supply the outer surface of the nose, and forms anastomoses with its contralateral fellow, and with the lateral nasal branch of the facial artery.[1]
Distribution
The dorsal nasal artery contributes arterial supply to the lacrimal sac,[1][3] and the outer surface of the nose.[1]
In around 20% of individuals, it also supplies the tip of the nose.[3]
