OBJECTIVES
This prospective study evaluated the accuracy of mandibular reconstruction using free fibular flaps (by comparing virtual plans to the three-dimensional postoperative results), and the extent of bone-to-bone contact after computer-assisted surgery.
METHODS
We included 65 patients who underwent partial-continuity mandibular resections from February 2013 to January 2017, and evaluated virtual planning, surgical techniques, and accuracy.
RESULTS
Forty-seven patients were analysed. A total of 112 fibular segments received 54 implants. We measured 227 distances between landmarks to assess the accuracy of reconstruction. Postoperative reconstruction accuracy ranged from 0.5 to 3 mm.
CONCLUSION
Virtual surgical planning very accurately translated simulation into reality, particularly in patients requiring large, complex mandibular reconstructions using multiple fibular segments.

目的
本前瞻性研究通过比较虚拟计划与三维术后结果，评估游离腓骨瓣在下颌骨重建中的准确性，以及计算机辅助手术后骨对骨接触的程度。
方法
我们纳入了 2013 年 2 月至 2017 年 1 月期间接受部分连续性下颌骨切除术的 65 例患者，并对虚拟规划、手术技术和准确性进行了评估。
结果
分析了 47 例患者。共 112 个腓骨段接受了 54 个植入物。我们测量了 227 个标志点之间的距离，以评估重建的准确性。术后重建的准确性为 0.5 至 3 毫米。
结论
虚拟手术规划非常准确地将模拟转化为现实，特别是对于需要使用多个腓骨段进行大型、复杂下颌骨重建的患者。
