Mechanism and Causes of Injury  The orbital contents are protected by a ring of strong bony abutments. These are composed of the supraorbital arch of the frontal bone superiorly; the zygoma laterally; the frontal process of the maxilla medially; and the thick rim of the orbital floor, formed by the zygoma and maxilla,
