Dissection of right orbit from a superior approach
Relation of aponeurosis of levator palpebrae superioris muscle to tendon of superior oblique muscle and lacrimal gland
The bone of the orbital margin has been resected and the fascia covering the levator palpebrae muscle removed. Subcutaneous structures of the supraorbital region (13-16) have been preserved along with the thickened rim of periorbita at the margin of the orbit (17). The superior orbital fissure (24) has been opened to display nerves which traverse it. The superior ophthalmic vein has been removed.
