Abstract:

BACKGROUND: Three-dimensional printing to prepare a digital model can improve the accuracy of orbital fracture repair, and has a good clinical prospect.
OBJECTIVE: To evaluate the effect of individualized titanium mesh based on the digital model in the reconstruction of orbital fracture.
METHODS: Twelve cases of orbital fracture were admitted at the Hospital of Stomatology, Southwest Medical University from January 2014 to October 2015. CT scanning in axial, coronal, sagittal planes and three-dimensional reconstruction were performed routinely in all cases preoperatively. Digital model was designed by 3D printing technology according to the CT data. Individualized titanium mesh was shaped based on the digital model and used to repair orbital fracture. The accuracy of the reconstructed orbit was assessed based on the postoperative CT scan.
RESULTS AND CONCLUSION: Postoperative CT scans showed that the implanted individualized titanium meshes were capable of accurately reconstructing the fractured orbit in all the 12 patients, and there was no infection, and titanium mesh loosening, prolapse, and rejection. With healthy eyes as controls, 11 cases of eyeball retraction were corrected completely, and only 1 case was still under correction. Diplopia symptoms disappeared in the 8 of 9 cases, and relieved in the 1 of 9 cases. Seven cases of eye movement limitation recovered postoperatively. To conclude, the individualized titanium mesh has great accuracy to repair orbital fractures in patients without serious complications, which has achieved good clinical outcomes in the orbital reconstruction.
