摘　　要：目的探讨头颈晚期恶性肿瘤125I粒子植入术中3D打印定位导板的设计、制作要点及其具体病例中的应用。方法通过我科的21例临床病例,介绍3D打印定位导板的设计与制作步骤,统计所有病例数据资料并分析。结果 3D打印完成患者的个性化125I粒子植入定位导板,手术操作简便,定位准确,术后复查CT显示粒子植入分布均匀,与术前目标一致,未发生重大植入偏差;18例复诊患者中,16例肿瘤明显缩小,仅有2例出现局部黏膜破溃。结论 3D打印定位导板可有效替代CT引导下125I粒子植入手术,减轻了医患射线暴露风险,简化了手术操作,该技术值得推广。Objective To discuss the design of 3D printing positioning guide plate in implantation,processing points and its application of cases in the surgical operation of ^（125）I radioactive particle implantation of the advanced head and neck malignancies. Methods The design and making steps of 3D printing guide plate by the 21 clinical cases of my department were described,and statistic data of all cases were analyzed. Results 3D print finished implanting the patients＇ personalized ^（125）I radioactive particle guide plate,bringing a more convenient surgical operation with higher positioning accuracy.And the postoperative review CT showed that the particle implantation was evenly distributed,which was consistent with the preoperative goals. There were no significant implantation deviations in all cases. Of the 18 referral patients,16 had a significantly reduced tumor,and only 2 had local mucosal rupture. Conclusions The technology of 3D printing guide plate can effectively substitute for the traditional CT-guided surgery of the ^（125）I radioactive particle implantation. It reduces the risk of radiation exposure around doctors and patients,simplifies the operation technology,which deserves promotion.
