The purpose of this study was to determine the accuracy of virtual surgical planning for mandibular reconstruction, along with the implementation of a postoperative evaluation methodology.
The study is a prospective case series for computer-assisted mandibular reconstruction surgery. Analysis of the degree of agreement between virtual measurements and postoperative actual outcomes was performed. The reliability of the proposed evaluation methodology was assessed and analyzed using the Inter-Class Coefficient (ICC) test. Statistical significance was set at the 5% level.
Nine consecutive patients were selected. The analysis of all angular and linear parameters reported a highly statistically significant degree of agreement between the preoperative and postoperative measurements (P < 0.001). Furthermore, an extreme degree of reliability was reported when the evaluation methodology was scrutinized (ICC = 0.9).
The excellent degree of agreement between the virtual plan and the actual outcome reported in this study validated the surgical accuracy of virtually assisted mandibular reconstruction. This study pointed out the reliability and reproducibility of the standardized evaluation protocol in an attempt to obtain a tolerable value for the acceptable postoperative results regarding the accuracy of computer-assisted surgery.
本研究旨在确定下颌骨重建的虚拟手术规划的准确性，并提出一种术后评估方法。
本研究是一项计算机辅助下颌骨重建手术的前瞻性病例系列研究。分析了虚拟测量值与术后实际结果之间的一致性程度。使用组内相关系数（ICC）检验评估和分析了所提出的评估方法的可靠性。统计显著性水平设定为 5%。
选择了 9 例连续患者。所有角度和线性参数的分析报告显示，术前和术后测量值之间具有高度统计学显著的一致性（P < 0.001）。此外，当仔细检查评估方法时，报告了极高的可靠性（ICC = 0.9）。
本研究报告的虚拟计划与实际结果之间的优异一致性验证了虚拟辅助下颌骨重建的手术准确性。本研究指出了标准化评估方案的可靠性和可重复性，试图为计算机辅助手术的准确性获得可接受的术后结果的可接受值。
