Abstract

Mixed reality (MR) is a further development of virtual reality technology. This technology builds an interactive feedback information loop between the virtual world, the real world and users by introducing real scene information into the virtual environment to enhance the reality of user experience. This study explores the application and value of MR technology in endoscopic surgery. In this study, patients with middle ear cholesteatoma who are to undergo endoscopic surgery were selected. After obtaining the informed consent of the patients, temporal bone CT is used to obtain clinical data information. The 3D model was built by online editing platform. When viewing the 3D digital model in the real environment of VR helmet, the model can also be moved, rotated, scaled and measured. Through MR technology, doctors can fully observe the details of the lesion, deeply excavate the image information, distinguish the relationship between the facial nerve, auditory ossicular chain and cholesteatoma lesion, and then work out a safer and more reasonable surgical plan. The application of MR technology in endoscopic surgery can build effectively communication between doctors and patients, and formulate a reasonable operation plan through ear canal approach, it can also help young doctors train their surgical skills. Key words: mixed reality; Endoscopic; Surgical Procedures, Operative
