Abstract:

Objective  This study aims to evaluate the effect of customized titanium mesh, which was designed by mirror imaging and rapid prototyping technique, with Medpor applied for orbital fracture with enophthalmos. Methods  Orbital axial, coronal, and sagittal CT scan, and three-dimension CT examination were performed routinely in 18 cases of orbital fracture with enophthalmos preoperatively. Based on the CT data, prosthesis model was designed by reverse engineering and rapid prototyping technique. The customized titanium mesh and Medpor were applied for orbital reconstruction and enophthalmos correction. Orbital reduction and globe projection were evaluated by postoperative CT scan and clinical follow-up visits. Results  CT scans revealed that the customized titanium mesh with Medpor had great accuracy to reconstruct the orbital fracture and correct the enophthalmos in all patients without serious complications. The eye and facial appearance and function recovered significantly. No serious complication occurred in the operation and after operation. Conclusion  The customized titanium mesh, based on mirror imaging and rapid prototyping technique, can accurately reconstruct the orbital fractures with enophthalmos. The application of Medpor can effectively correct enophthalmos and eyeball mobility malformation.
