Oribital floor fractures: a retrospective study.

A retrospective series of 365 orbital floor fractures was studied and many variables were analyzed. Some type of ocular or orbital adnexal damage was present in 32% of the patients. After a repair procedure there was a low incidence of decreased visual acuity, and there were no implant extrusions. Late enophthalmost and diplopia were found to be related to the type of orbital floor damage. The comminuted floor fractures and fractures associated with prolapse of orbital tissue into the maxillary antrum were more prone to demonstrate these late sequelae. Despite various surgical procedures there was a 19% incidence of late diplopia and an 11% incidence of late enophthalmos.
