Today, virtual simulation environments create alternative hands-on practice opportunities for surgical training. In order to increase the potential benefits of such environments, it is critical to understand the factors that influence them. This study was conducted to determine the effects of training, used-hand, and experience, as well as the interactions between these variables, on endoscopic surgery skills in an educational computer-based surgical simulation environment. A 2-hour computer-based endoneurosurgery simulation training module was developed for this study. Thirty-one novice- and intermediate-level resident surgeons from the departments of neurosurgery and ear, nose, and throat participated in this experimental study. The results suggest that a 2-hour training during a 2-month period through computer-based simulation environment improves the surgical skills of the residents in both-hand tasks, which is necessary for endoscopic surgical procedures but not in dominant hand tasks. Based on the results of this study, it can be concluded that computer-based simulation environments potentially improve surgical skills; however, the scenarios for such training modules need to consider especially the bimanual coordination of hands and should be regularly adapted to the individual skill levels and progresses.
如今，虚拟仿真环境为外科手术培训创造了替代性的实践机会。为了增加此类环境的潜在益处，了解影响它们的因素至关重要。本研究旨在确定培训、惯用手和经验，以及这些变量之间的相互作用，对基于计算机的教育性手术模拟环境中的内镜手术技能的影响。为此研究开发了一个2小时的基于计算机的神经内镜手术模拟训练模块。来自神经外科和耳鼻喉科的31名初、中级住院医师参与了这项实验研究。结果表明，在两个月的时间里通过基于计算机的模拟环境进行2小时的培训，可提高住院医师在双手任务中的手术技能，这是内镜手术操作所必需的，但在优势手任务中则不然。基于本研究结果，可以得出结论，基于计算机的模拟环境有可能提高手术技能；然而，此类训练模块的场景需要特别考虑双手的协调，并且应定期根据个人技能水平和进展情况进行调整。
