Use and Evaluation of Patient-Specific Titanium Implant for Delayed Repair of Posttraumatic Frontonasoethmoidal and Supraorbital Bone Defect

Abstract

A 53-year-old female patient was referred to us with a posttraumatic frontoorbital deformity following motor vehicle accident after 2 months of her injury. Using the virtual surgical planning software, comprehensive analysis of the deformity, and preoperative planning was simulated. The reconstruction of the defect was then determined and approximated to the skull of the reference database. Patient-specific implant is manufactured by selected laser melting of titanium powder grade 2, which yielded a highly accurate personalized implant. The good postoperative outcome was satisfactorily achieved. The postoperative result was also comparable to the predicted outcome as showed via chromatographic analysis method. Not only being less invasive, the operative time was also remarkably reduced as compared with the conventional reconstruction method of similar cases.
