4.1.2.2 The Supratrochlear Artery

The supratrochlear artery is a branch of the ophthalmic artery along with the supraorbital artery. The internal carotid artery branches from the ophthalmic and the supratrochlear artery posterior to the trochlear, perforates the medial orbital septum, and runs to the glabellar area. It tends to create an anastomosis with the contralateral supratrochlear artery.

After exiting the orbit, it runs superficially, so skin necrosis often occurs after injections are made to correct glabellar frown lines . This area is relatively thick, so it involves a higher risk of compression (Figs. 4.8, 4.9, 4.10, and 4.11).
