THE TREATMENT OF CRANIOFACIAL GUNSHOT WOUNDS WITH INDIVIDUAL IMPLANTS

Abstract

Background: Demonstrate the use of advanced three-dimensional (3D) computer technology, virtual surgical planning (VSP), three-dimensional modeling (3DM), and the treatment of complex craniofacial gunshot injuries. Methods: We present a clinical series reports of craniofacial gunshot Injuries using modern 3D computer technology. Based on the CT images of the skull, a CAD model of the skull (biomodel) and a restorative implant were digitally constructed. The biomodel was then physically constructed using 3D printing. Comparison of the dimensions of the implant and its corresponding biomodel revealed geometric correspondences. Manufactured prostheses used for the reconstruction of craniofacial defects formed after gunshot wounds. Results: There were no complications in the perioperative period, infection or exposure of the implant in the postoperative period. The results of the study showed that the imprinted individual cranial implants had a high dimensional accuracy, demonstrating clinically acceptable morphological similarity in terms of fit and contour continuity. Patients are satisfied with the aesthetic (improvement of the skull contour) and functional results of reconstruction. Conclusion: Individual implants for the reconstruction of craniofacial defects have shown effectiveness, which is associated with more accurate adaptation to the implantation site, reduced surgery time and better cosmetic effect.
