Definition
The orbital surface of greater wing is a quadrilateral-shaped surface that forms part of the lateral and posterior aspects of the eye socket. In the eye socket’s lateral wall, it articulates with the zygomatic bone at the front and to the orbital plate of the frontal bone towards the front and top. At the back, the superior orbital fissure separates the orbital surface of greater wing from the lesser wing in the roof of the eye socket, and the inferior orbital fissure separates it from the bones in the floor of the eye socket.
