【摘要】 目的 探讨颅颌面整形手术机器人在颏部水平截骨手术中的应用效果和精确性。方法 回顾分析2015年1月至2020年12月接受传统颏部水平截骨手术的10例小颏畸形患者（临床组）的临床资料，并通过颅颌面整形手术机器人对该组患者1∶1的3D石膏模型（机器人组）进行颏部水平截骨手术操作。以本团队前期实验研究数据标准为参考，利用数字化模拟软件设计术前理想手术方案（对照组）。分别测量3组的颏前点至鼻根点的距离，前鼻棘点至颏下点的距离，颏顶点至颏孔点的距离，颌角点至颏孔点的距离，双侧下颌1、3、6号牙顶点至截骨线的距离，内固定与颏前点的最小距离，对比3组指标测量结果。结果 机器人组术后测量指标与对照组指标无明显统计学差异（P>0.05），临床组术后测量指标与对照组指标统计学差异明显（P<0.05）。机器人组与对照组的截骨路线一致（P>0.05），而临床组与对照组的截骨路线之间存在差异（P<0.05）。临床组与机器人组相比，术后的内固定与颏前点的最小距离更小。结论 与传统临床手术操作相比，颅颌面整形手术机器人可以更加精准地进行颏部水平截骨。更多还原

【Abstract】 Objective To explore the application effect and accuracy of craniomaxillofacial plastic surgery robot in genioplasty. Methods The clinical data of 10 patients treated with traditional clinical genioplasty(clinical group) from January 2015 to December 2020 was retrospectively analyzed and compared with the data of their 1 ∶1 3D plaster model underwent genioplasty via cranio-maxillofacial plastic surgery robot(robot group). Based on the pre-experimental research data standards of our department, the ideal preoperative surgical scheme(control group) was designed using digital simulation software. The distance between pogonion and nasion, the distance between anterior nasal spine and menton, the distance between gnathion and mental foramen, and the distance between gonion and mental foramen, the distance from incision inferior, tip of lower canine and tip of the molar cheek groove to the line of osteotomy, the closest distance between screw and mental foramen were measured and compared among the three groups. Results There were no statistical differences between the robotic group and control group in the postoperative measurement index(P>0.05), and there was a statistical difference between the clinical group and the control group in the postoperative measurement index(P<0.05). There was no statistical difference between robotic group and control group in line of osteotomy(P >0.05),but there was a statistical difference between the clinical group and the control group in line of osteotomy(P<0.05). Compared with the robotic group, the closest distance between screw and mental foramen after operation was smaller in the clinical group. Conclusion Compared with the actual operation of human hands, the cranio-maxillofacial plastic surgery robot can perform genioplasty more accurately.更多还原
