Bilateral orbital floor fractures.

Nineteen patients operated on suspicion of bilateral orbital floor fractures are described. All of the patients had severe comminute midfacial fractures. Orbital floor deficiency requiring transplantation was found in 68% of the cases, demonstrating homolateral maxillary and zygomatic fractures. On the basis of their findings, the authors recommend acute reposition of the fractures and routine exploration of the orbital floor in the case of deficiencies requiring transplantation and in cases of homolateral combined maxillary and zygomatic fractures.
