Mixed Reality Assisted Orbital Reconstruction Navigation System for Reduction Surgery of Orbital Fracture

To achieve an optimal clinical outcome in orbital fracture reduction surgery (OFRS), accurate localization of the orbital bone is essential. The mixed reality (MR) technology, which also called augmented reality (AR) through optical see-through head-mounted displays (OST-HMD), offers a promising new approach to visualization and navigation in the operating room. We hypothesized that the MR navigation is a feasible, reliable and accurate guide-wire in the orbital bone positioning and visualization in treatment surgery of orbital fracture. Focus on the navigation during OFRS, a specific marker is designed and adopted to perform registration step and the OST-HMD is used as display platform in the navigation system. Model experiments are conducted to evaluate the clinical application value.
