Enophthalmos and Diplopia in Fractures of the Orbital Floor

Summary Fractures involving the weak portion of the floor of the orbit are more frequent than usually assumed. They occur either in association with fractures of the stronger anterior rim of the orbital floor, or independently as a result of increased intraorbital pressure, the blow-out fracture. Orbital floor fractures are the cause of traumatic enophthalmos and diplopia. Prevention of these complications can be achieved only by direct verification of the condition of the floor of the orbit through the maxillary sinus approach and by early restoration of the floor of the orbit by bone grafts.
