Segmental Le Fort I surgery is an effective technique to correct complicated dentomaxillofacial deformities. This retrospective study evaluated the accuracy of segmental Le Fort I surgery under the guidance of virtual surgical planning (VSP). A total of 129 patients who accepted segmental Le Fort I surgery were investigated in this study. VSP was transferred to segmental surgery with different pieces precisely with the aid of 3D-printed surgical templates and splints. The surgical result was evaluated by postoperative complications, color distance maps, and quantitative accuracy analysis. Outcomes showed that the VSP was successfully transferred to actual surgery with high accuracy. The overall mean linear difference was 1.28 mm, and the overall mean angular difference was 2.4°. Except for one case of root injury, there was no serious complication recorded. The results suggested that VSP was a reliable assistance for segmental Le Fort I surgery.
节段性 Le Fort I 截骨术是一种矫正复杂牙颌面畸形的有效技术。本回顾性研究评估了虚拟手术规划（VSP）指导下节段性 Le Fort I 截骨术的准确性。本研究共调查了 129 例接受节段性 Le Fort I 截骨术的患者。借助 3D 打印手术模板和夹板，VSP 被精确地转移到不同的节段手术中。通过术后并发症、颜色距离图和定量准确性分析来评估手术结果。结果表明，VSP 能够高精度地成功转移到实际手术中。整体平均线性差异为 1.28mm，整体平均角度差异为 2.4°。除 1 例根损伤外，无严重并发症记录。结果表明，VSP 是节段性 Le Fort I 截骨术的可靠辅助手段。
