Fractures of the orbital floor: indications for exploration and for the use of a floor implant

Abstract

Fractures of the orbital floor are frequently treated by exploratory surgery and by the insertion of a floor implant, because of the possibility of late diplopia and enophthalmos. The findings of this study would suggest that this fear is not justified and that there is no indication for an early diagnostic exploration of the fractured orbital floor, if there are no clinical or radiological signs of orbital floor fracture within 14 days of the accident. The significance of the status of the periorbita in the method of treatment of the fractured orbital floor is stressed. The suggestion is made, contrary to what is generally found in the literature, that a linear or a comminuted floor fracture and an orbital floor with a defect do not require a floor implant, if the periorbita is intact.
