The frontal vein (supratrochlear vein) begins on the forehead in a venous plexus which communicates with the frontal branches of the superficial temporal vein. The veins converge to form a single trunk which runs downward near the middle line of the forehead parallel with the vein of the opposite side. The two veins are joined at the root of the nose by a transverse branch called the nasal arch which receives some small veins from the dorsum of the nose.
