| Abstract | ||
| Background: Orbital blow out fracture can alter cavity dimensions and position of intra-orbital contents. Anatomical reduction and reconstruction of the orbital fracture is important for preventing latter complications. Introduction of medical software for virtual surgical planning and printing of stereolithographic (STL) models, allows the clinician to pre-bent the titanium orbital meshwork preoperatively reproducing accurate osseous anatomy. This reduces the risk of free hand orbital meshwork (FOM) malposition, poor anatomical contour and trauma to soft tissues. Aim of the study: The aim of this study was to compare the orbital volume when using (STL) model versus (FOM) in the treatment of patients with unilateral orbital floor fracture. Materials and Methods: Sixteen patients were included in this study. Chief complaint was orbital facial asymmetry related to an accident. Patients were divided into two groups, eight patients in each group. Group I was treated via (STL) model and group II with (FOM). Orbital volume ratio (OVR) then differential volumetric percentage were calculated for both groups. P value < 0.05 was considered significance. Results: Measurements of orbital volume comparing the repaired side to the normal side; of group I revealed non-significant difference, while in group II revealed significant difference. Measurements of orbital volume comparing group I and group II revealed significant difference. Conclusion: The application of (STL) technology in a unilateral orbital cavity reconstruction gives a good understanding of the anatomical state of the injured orbit. | ||
