The Anterior Ethmoidal Artery is an artery in the human anatomy that supplies oxygenated blood to the ethmoidal cells and the frontal sinus. It is a branch of the ophthalmic artery, which itself is a branch of the internal carotid artery.

Anatomy

The anterior ethmoidal artery originates from the ophthalmic artery in the orbit, travels through the ethmoid bone, and enters the nasal cavity. It then branches off to supply the ethmoidal cells and the frontal sinus.

Clinical Significance

The anterior ethmoidal artery is important in surgical procedures involving the sinuses, as damage to this artery can lead to severe bleeding. It is also a landmark for surgeons during endoscopic sinus surgery.
