Abstract:

Objective To study the characters of the diagnosis and treatment for midfacial fractures with orbital floor fractures. Methods 136 cases of midfacial fractures with orbital floor fractures were diagnosed and treated. All patients underwent CT scans and accepted surgical intervention. Orbital floor fracture was restituted in 49 cases. Orbital floor defects were reconstructed with autogenous bone, titanium mesh or porous polyethylene implant（Medpor）in 21 cases. Results 136 cases recovered well，their facial appearance and function were improved significantly. There were no severe complications happened postoperatively in all cases. 2 cases had postoperative wounds infection and 1 case had temporary ablepsia, but healed completely. Conclusion CT is the best method for diagnosing orbital floor fractures. The objective of treatment is restoration of normal orbital floor and orbital capacity, the reduction of orbital contents prolapsed and reconstruction of orbital floor fractures with repair materials.
