背景计算机辅助手术的引入是面部骨骼缺损功能重建的一个里程碑。患者和方法我们比较了五个计算机辅助和五个传统的重建腓骨移植在试点研究的过程中。快速原型制作指南将计算机辅助手术计划转化为术中可用模型。我们在术中测量了移植物成形到受体部位所需的时间和缺血时间。此外，评估了供区缺损的大小与所需移植长度的比较。结果与无切割导向器的传统手术相比，成形过程和缺血时间明显缩短（p = 0.001）。0.014）。使用手术导向器，腓骨缺损尺寸和必要的移植尺寸之间没有变化。在传统手术中，平均变化1.92？cm发生率（p = 0.001）。0.001）。结论手术导向器可显著缩短成形时间，从而缩短缺血时间。这些因素都会影响皮瓣成活。腓骨供区缺损缩小。版权所有（C）2011约翰威利父子有限公司
Background The introduction of computer-assisted surgery was a milestone in functional reconstructions of facial skeletal defects. Patients and methods We compared five computer-assisted and five conventional reconstructions with fibular grafts in the course of a pilot study. A rapid prototyping guide translated the computer-assisted surgery plan into intraoperative utilizable models. We intraoperatively measured the time needed for shaping the graft to the recipient site and the ischaemic time. Furthermore, the size of donor site defect compared to the required transplant length was evaluated. Results Shaping procedure and ischaemic time turned out significantly shorter when compared to conventional surgery without cutting guide (p?=?0.014). Using surgical guides, there was no change between the defect size of the fibula and the necessary transplant size. In conventional surgery, a mean change of 1.92?cm occurred (p?=?0.001). Conclusion The surgical guide significantly reduced shaping time and consequently ischaemic time. These factors can influence flap survival. The fibular donor site defect was downsized.
