Supratrochlear

Supratrochlear artery

The Supratrochlear artery is a branch of the ophthalmic artery that supplies blood to the forehead and scalp. It is a significant artery in the human anatomy and plays a crucial role in the circulatory system.

Anatomy

The supratrochlear artery originates from the ophthalmic artery, which is a branch of the internal carotid artery. It travels upwards and forwards, passing above the pulley of the superior oblique muscle and beneath the supraorbital margin and frontalis muscle. It then divides into two branches, one of which supplies the forehead and the other the scalp.

Function

The primary function of the supratrochlear artery is to supply blood to the forehead and scalp. It also provides blood to the frontalis muscle, superior oblique muscle, and the skin of the upper eyelid.

Clinical significance

The supratrochlear artery is of clinical significance in several medical procedures, including forehead lift and blepharoplasty. It is also important in the diagnosis and treatment of migraine and temporal arteritis.
