Abstract：
UNASSIGNED: The purpose of this study was to compare the accuracy of hard tissues movements planned to result of the maxillary and mandibular positions between conventional surgical planning (CSP) and virtual surgical planning (VSP) in patients undergoing orthognathic surgery.
UNASSIGNED: A systematic electronic search was carried out in six databases and gray literature with no restriction of publication date and language. Clinical observational studies that compared accuracy of maxillary position between CSP and VSP were included. Linear measurements of the mandible in the transverse plane and linear measurements of the maxilla in the vertical, horizontal and transverse planes were considered for analysis, comparing planned to postoperative outcomes of CSP and VSP. Cochrane tool was used to assess bias risk. A meta-analysis was performed to summarize similar results by using the Review Manager 5.3 software. Significance level was set at 5%.
UNASSIGNED: Six studies (2 RCT and 4 retrospective cohorts) were included according to inclusion and eligibility criteria, involving 255 patients. The inter-rater reliability of selection and eligibility was excellent (k = 0.8315 and k = 0.9329, respectively). Two studies presented that VSP seemed to have better results than CSP regarding linear measurements of the mandible in the transverse plane. Results from CSP and VSP were similar in accuracy for hard tissue in vertical plane of maxillary position (I2 = 0%; p = 0.17), although VSP was more accurate in horizontal plane (I2 = 0%; p = 0.02).
UNASSIGNED: VSP presented better accuracy for transverse movements in mandible of asymmetric patients. VSP showed to be more accurate for movements in the horizontal plane, and qualitative analysis seemed to be more effective for transverse movements.

摘要：
■这项研究的目的是比较在正颌手术患者中，传统手术计划（CSP）和虚拟手术计划（VSP）之间的上颌和下颌位置所计划的硬组织运动的准确性。
■在六个数据库和灰色文献中进行了系统的电子搜索，没有发布日期和语言的限制。包括比较CSP和VSP上颌位置准确性的临床观察性研究。下颌骨在横向平面的线性测量和上颌骨在垂直方向的线性测量，水平和横向平面被考虑进行分析，比较CSP和VSP的计划与术后结果。使用Cochrane工具评估偏倚风险。使用ReviewManager5.3软件进行荟萃分析以总结相似的结果。显著性水平设定为5%。
■根据纳入和资格标准纳入了六项研究（2项RCT和4项回顾性队列）。255名患者。选择和资格的评估者间可靠性优异(分别为k=0.8315和k=0.9329)。两项研究表明，在横向平面中对下颌骨进行线性测量方面，VSP似乎比CSP具有更好的结果。CSP和VSP的结果在上颌位置的垂直平面上对硬组织的准确性相似（I2=0％；p=0.17），尽管VSP在水平面更准确(I2=0%;p=0.02)。
■VSP对不对称患者下颌骨的横向运动具有更好的准确性。VSP显示出在水平面的运动更准确，定性分析似乎对横向运动更有效。
