Abstract
Mixed reality (MR), characterized by the ability to integrate digital data into human real feeling, is a new technique in medical imaging and surgical navigation. MR has tremendous value in surgery, but its application in oromaxillofacial head and neck oncology surgery is not yet reported. This paper reports the application of MR in oromaxillofacial head and neck oncology surgery. The merits, demerits, and present research situations and prospects of MR are further discussed.
