Clinical and Radiographic Evaluation of Three-Dimensional Pre-Bent Orbital Plates in Management Of Orbital Fractures.

Purpose The aim of this study is to compare and evaluate clinically and radiographically the validity of using standard preformed and three-dimensional anatomical orbital implants in the reconstruction of post-traumatic internal orbit defects. Method This clinical study included randomly selected eighteen patients from two groups, nine patients each, that are amenable to internal orbital reconstruction. All patients enrolled in this study underwent clinical examination and radiographic examination using CT scans preoperatively and immediately postoperatively, and preoperative stereolithographic three-dimensional mirrored printed orbital models for group patients treated with standard preformed implants. Also, surgical approaches were performed through transcutaneous or transorbital approaches. All patients were followed up radiographically one day postoperatively and had three clinical follow-up visits in one week, four weeks, and twelve weeks. Orbital volume, corneal projection, motility restriction, visual acuity, diplopia, and implant contour analysis were used as calipers evaluating the accuracy of orbital reconstruction. Results Both groups showed significant reductions in orbital volume postoperatively (Group A: p < 0.001, Group B: p = 0.02, but no significant difference was found between the groups (p > 0.05). However, 3D anatomical titanium orbital implants performed better, yielding both superior positioning and faster surgeries. Conclusion Both standard preformed and 3D anatomical titanium orbital implants have shown comparable results in primary orbital reconstruction. The 3D anatomical orbital implant reduces surgical time and provides a more exact and simpler technique for repairing medial orbital wall fractures.
