Abstract：
The aim of this study was to make an economic analysis and evaluation of a low-cost virtual surgical planning (VSP) protocol that was developed in house, and based on open-source software and a desktop 3-dimensional printer. All eight patients between April 2014 and 2015 who had been treated by mandibular reconstructions with microvascular fibular flaps that had been planned using the protocol were retrospectively analysed for accuracy, time, and cost. Median differences for planned compared with postoperative intercondylar distance, intergonial distance, and gonial angle did not differ significantly. A median (range) labour time of 85 (€57-124) minutes was needed. An evaluation of cost, including labour, showed an additional median (range) cost/patient of € 276 (€257.50-297.25). With the acquisition cost of the 3-dimensional printer omitted, there was a negligible additional cost/patient of €44.75 (€26.25-66). All planning was done by the junior surgeon and there was a steep learning curve. Our new VSP protocol is cost-effective, easy to use, and has an accuracy comparable with that of a standard VSP protocol. To the best of our knowledge this is the first report of an open-source software protocol in which the labour costs of the planning by a surgeon are included.
摘要：
这项研究的目的是对内部开发的低成本虚拟手术计划（VSP）协议进行经济分析和评估，并基于开源软件和桌面三维打印机。对2014年4月至2015年之间的所有8例患者进行了回顾性分析，这些患者通过计划使用该方案的微血管腓骨皮瓣进行了下颌骨重建治疗。时间,和成本。计划与术后髁间距离的中位数差异，间距,和阴角没有显着差异。需要85（€57-124）分钟的中位（范围）劳动时间。对成本的评估，包括劳动，显示额外的中位数（范围）费用/患者为276欧元（257.50-297.25欧元）。省略了三维打印机的购置成本，有一个微不足道的额外费用/患者44.75欧元(26.25-66欧元).所有计划都由初级外科医生完成，学习曲线陡峭。我们的新VSP协议具有成本效益，易于使用,并且具有与标准VSP协议相当的准确性。据我们所知，这是开源软件协议的第一份报告，其中包括外科医生计划的人工成本。
