Virtual surgical planning (VSP) is becoming more widely used in maxillofacial reconstruction and can be or . Surgeon-based models require software training but allow surgeon autonomy. We evaluate the learning curve for VSP through a prospective cohort study in which planning times and accuracy of 7 otolaryngology residents with no prior VSP experience were compared to that of a proficient user after a single training protocol and 6 planning sessions for orbital fractures. The average planning time for the first session was 21 minutes 41 seconds ± 6 minutes 11 seconds with an average maximum deviation of 2.5 ± 0.8 mm in the lateral orbit and 2.3 ± 0.6 mm in the superior orbit. The average planning time for the last session was 13 minutes 5 seconds ± 10 minutes and 7 seconds with an average maximum deviation of 1.4 ± 0.5 mm in the lateral orbit and 1.3 ± 0.4 mm in the superior orbit. Novice users reduced planning time by 40% and decreased maximum deviation of plans by 44% and 43% in the lateral and superior orbits, respectively, approaching that of the proficient user. Virtual surgical planning has a quick learning curve and may be incorporated into surgical training.
虚拟手术规划（VSP）在颌面重建中的应用越来越广泛，可用于[此处原文缺失部分内容]。基于外科医生的模型需要软件培训，但赋予外科医生自主权。我们通过一项前瞻性队列研究评估VSP的学习曲线，在该研究中，将7名无VSP经验的耳鼻喉科住院医师在接受单次培训方案和6次眼眶骨折规划课程后的规划时间和准确性与一名熟练用户进行比较。第一次课程的平均规划时间为21分41秒±6分11秒，外侧眼眶的平均最大偏差为2.5±0.8毫米，上方眼眶为2.3±0.6毫米。最后一次课程的平均规划时间为13分5秒±10分7秒，外侧眼眶的平均最大偏差为1.4±0.5毫米，上方眼眶为1.3±0.4毫米。新手用户的规划时间减少了40%，外侧和上方眼眶规划的最大偏差分别减少了44%和43%，接近熟练用户的水平。虚拟手术规划具有快速的学习曲线，可纳入手术培训。
