Intraoperative imaging is increasingly used by surgeons and has become an integral part of many surgical procedures. This study was performed to provide an overview of the current literature on the intraoperative use of cone beam computed tomography (CBCT) imaging in maxillofacial surgery. A bibliographic search of PubMed was conducted in March 2020, without time limitation, using "intraoperative imaging" AND "maxillofacial surgery" AND "cone beam computed tomography" as key words. Ninety-one articles were found; after complete reading, 16 articles met the eligibility criteria and were analysed. The results showed that the majority of the indications were related to maxillofacial trauma, particularly zygomaticomaxillary complex fractures. Final verification with intraoperative CBCT before wound closure was the most common use of this device. However, innovative uses of intraoperative CBCT are expanding, such as CBCT coupling with mirror computational planning, and even the combined use of initial intraoperative CBCT acquisition with navigation. Immediate, fast, and easy evaluation of bone repositioning to avoid the need for further surgical revision is the main advantage of this technique. Imaging quality is comparable to that of multi-slice computed tomography, but with lower radiation exposure. Nevertheless, CBCT is still not widely available in maxillofacial centres, probably because of its cost, and perhaps because not everyone is aware of its advantages and versatility, which are reported in this review.
术中成像越来越多地被外科医生使用，并已成为许多外科手术的重要组成部分。本研究旨在提供术中使用锥形束 CT（CBCT）成像在颌面外科中的应用的文献综述。2020 年 3 月，我们在 PubMed 上进行了无时间限制的文献检索，使用“术中成像”和“颌面外科”和“锥形束 CT”作为关键词。共发现 91 篇文章；经过完整阅读，有 16 篇文章符合纳入标准并进行了分析。结果表明，大多数适应证与颌面外伤有关，特别是颧骨-上颌骨复合体骨折。在关闭伤口前用术中 CBCT 进行最终验证是该设备最常见的用途。然而，术中 CBCT 的创新用途正在扩大，例如 CBCT 与镜像计算规划相结合，甚至将初始术中 CBCT 采集与导航相结合。该技术的主要优点是可以立即、快速和轻松地评估骨复位情况，避免需要进一步的手术修正。成像质量与多层 CT 相当，但辐射暴露较低。然而，CBCT 仍然没有在颌面中心广泛应用，可能是因为其成本，也可能是因为并非所有人都意识到其优势和多功能性，本综述报告了这些优势和多功能性。
