Orbital fracture is a common traumatic deformity, and it can cause functional and esthetical problems. However, limited intra-operative view and complex anatomy make the reconstruction difficult. 3D surgical software systems have been used for the patient safety and reliable outcomes, but these are not specialized for the surgery and time-consuming manual works are needed frequently. Thus, we propose a virtual surgical planning and implant design system. We focus on increasing usability by automated functions and minimized user interaction. There are four main modules in the proposed system. First, 3D patient’s model is automatically reconstructed from CT data, and the next, the fractured region is detected and visualized. Based on the detected area, patient-specific implant is designed using template models. After the surgery, pre- and post-operative 3D models can be compared and analyzed. The average processing time takes about 4 minutes for the automated 3D modeling and fracture detection. We expect that our system can reduce pre-operation time and improved surgical outcomes can be derived by using patient-specific 3D printed implant.
