The supratrochlear artery arises as one of the two terminal branches of the ophthalmic artery, the other being the external nasal artery.


Accompanied by the supratrochlear nerve, the supratrochlear artery leaves the orbit superomedially. It ascends on the forehead.


There are no named branches, however, the supratrochlear artery anastomosis with the supraorbital artery and its fellow from the opposite side.
