Supratrochlear vein
The supratrochlear vein drains a venous plexus on the anterior forehead and scalp . It is a tributary of the angular vein along with the supra-orbital vein .
Gross anatomy
The supratrochlear vein descends down the medial part of the forehead until it reaches the root of the nose where it is connected to its contralateral partner by the transverse nasal arch . The vein then has two branches, one which enters the supratrochlear foramen/notch and one which unites with the supra-orbital vein to become the angular vein . The supratrochlear vein runs a parallel and medial course to the supratrochlear artery .
