Reconstruction of orbital floor fractures with maxillary bone
1Department of Otolaryngology-Head and Neck Surgery, Mount Sinai School of Medicine, New York, NY 10029, USA.
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.
