Along with the rapid development of road traffic in China, high-energy injuries to the maxillofacial region caused by motor vehicle traffic accidents are increasing year by year. The zygomatic bone and zygomatic arch, as the bony scaffold of the midface shape, are prominently located and easily destroyed in trauma, and their trauma usually involves three anatomical regions: zygomatic body, zygomatic arch and orbit, and fracture displacement of these three anatomical regions will lead to a series of obvious facial deformities and dysfunctions such as facial collapse, diplopia, inward and downward eye sink. On the other hand, the difference in medical level between regions in China and the need to prioritize the treatment of critical organs in the treatment of compound injuries have led to the emergence of a large number of old fractures of the zygomatic orbit and their traumatic deformities and dysfunctions. Zhang Yi, Department of Maxillofacial Surgery, Peking University Stomatological Hospital, Beijing, China However, the treatment of zygomatic-orbital old fractures has been a major problem in the treatment of trauma in oral and maxillofacial surgery, with poor results and difficulties in clinical treatment: (1) lack of quantitative diagnosis before surgery; (2) irregular zygomatic bone morphology, no obvious anatomical marker points, old fractures are difficult to be accurately reset, and the intraoperative position mostly relies on the operator’s experience; (3) the orbital wall is thin, and the fracture can only be restored by The orbital wall can only be restored by orbital reconstruction after fracture, but its morphology is irregular and the traditional surgical method cannot achieve anatomical reconstruction of the orbit; (4) there is a lack of objective evaluation means in the immediate postoperative period, and the long-term effect cannot be accurately predicted. Since computed tomography was widely used in oral and maxillofacial surgery in the 1980s, a series of computer-aided techniques have been gradually applied to craniomaxillofacial trauma treatment, making quantitative diagnosis, precise restoration and quantitative analysis possible, and gradually forming the concept of digital precise treatment. A large number of studies have also focused on the treatment of old fractures of the zygomatic orbit and proved that digital surgical technology is an effective means to solve this treatment challenge. By integrating the current mature digital surgical technology and developing a reasonable and optimized procedure, we can realize a precise treatment procedure that integrates preoperative precise design, intraoperative precise positioning, and postoperative objective evaluation, thus achieving precise treatment of orbital fractures with good clinical results.
