这项对照研究的目的是评估一种新的颧骨成形术模板系统的准确性和临床有效性。88例患者随机分为两组：实验组(使用膝成形术模板)和对照组(不使用膝成形术模板)。试验组根据计算机化的手术计划设计模板，采用三维打印技术进行制作。模板系统包括一个切割导向器和一对重新定位导向器。对照组采用传统的术中测量方法，不使用颧骨成形术模板。结果评估是通过比较计划结果和术后结果来完成的。使用均方根偏差(RMSD)和Bland-Altman方法测量和报告下巴的线性和角度差异。所有手术均顺利完成。使用颧骨成形术模板没有困难。实验组最大RMSD前后方向为1.1 mm，螺距方向为2.6°。无模板对照组最大RMSD为2.63 mm，螺距方向为7.2 1°。我们的研究结果表明，与传统的术中测量相比，这种颧骨成形术模板系统提供了更高的下巴定位准确度，并且计算机化的计划可以准确地传输给患者进行颧骨成形术。
The purpose of this control study was to assess the accuracy and clinical validation of a novel genioplasty template system. Eighty-eight patients were enrolled and divided into 2 groups: experimental group (using genioplasty templates) and control group (without genioplasty templates). For the experimental group, the templates were designed based on computerized surgical plan and manufactured using three-dimensional printing technique. The template system included a cutting guide and a pair of repositioning guides. For the control group, traditional intraoperative measurements were used without genioplasty templates. The outcome evaluation was completed by comparing planned outcomes with postoperative outcomes. Linear and angular differences for the chin was measured and reported using root mean square deviation (RMSD) and the Bland-Altman method. All surgeries were successfully completed. There was no difficulty to use genioplasty templates. For the experimental group, the largest RMSDs were 1.1 mm in anteroposterior direction and 2.6° in pitch orientation. For the control group without templates, the largest RMSDs were 2.63 mm in superoinferior direction and 7.21° in pitch orientation. Our findings suggest that this genioplasty template system provides greater accuracy in repositioning the chin than traditional intraoperative measurements, and the computerized plan can be transferred accurately to the patient for genioplasty.
