Objective: To evaluate the use of autogenous maxillary bone for the repair of orbital floor defects secondary to blunt facial trauma. Design: Retrospective case series of 41 patients with a mean follow-up of 1.7 years. Setting: Major metropolitan teaching hospital. Patients: Forty-one consecutive patients who underwent repair of orbital floor fractures with maxillary antral wall bone grafts. Main Outcome Measures: Presence of diplopia, orbital dystopia, implant extrusion, enophthalmos, infection, and donor site complications. Results: On follow-up clinical examinations, none of the 41 patients presented with any evidence of orbital dystopia or complications relative to the implant or donor site. Two patients had persistent enophthalmos, and 4 had persistent infraorbital nerve paresthesia. Postoperative computed tomographic scans in 12 patients revealed an adequate maintenance of orbital volume without any evidence of resorption of the graft. Conclusion: The use of maxillary antral wall bone for the repair of orbital floor fractures is a highly reliable technique that carries minimal morbidity.
