Reconstruction of Orbital Fracture with the Aid of Mirror Imaged 3D Printed Models

Abstract

Background: The use of mirror-imaging techniques with the aid of three-dimensional computed tomographic (3DCT) scanning and 3D printing for reconstruction of orbital fractures could improve the outcome and maximize the functional and esthetic reconstruction of traumatized orbit. Objective: The aim of the present study was to evaluate reconstruction of orbital fracture with the aid of mirror imaged 3D printed models. Patients and Methods: A total of 10 patients with unilateral orbital fractures were selected from those having maxillofacial injuries at the emergency room of Sayed Galal University Hospital, AlAzhar University, Cairo. Patients were divided randomly into two groups (five patients each); Group I: patients were treated with mirror imaging technique and fabrication of a rapid prototype skull model. Group II: patients were treated through the traditional technique without fabrication of a rapid prototype skull model. Results: At one, three and six months postoperatively, all patients affected with diplopia within both groups have a total recovery. The difference was statistically significant. The traumatized orbits were reduced and fixed in both groups through either technique and there was a statistically insignificant difference in mean orbital volume in unaffected side and the affected side (immediately postoperatively). Conclusion: It could be concluded that the use of mirror image rapid prototype skull model for treatment of orbital fractures has no advantage over the traditional method.
