The aim of this paper is to analyze the results of virtual reality (VR) antromastoidectomy simulation training and the transferability of the obtained skills to real temporal bone surgery.
The study was conducted prospectively on a group of 10 physicians, and was composed of five VR simulation training sessions followed by live temporal bone surgery. The quality of performance was evaluated with a Task-Based Checklist (TBC) prepared by John Hopkins Hospital. Additionally, during every VR session, the number and type of mistakes (complications) were noted.
The quality of performance measured by the TBC increased significantly during consecutive VR sessions. The mean scores for the first and fifth sessions were 1.84 and 4.27, respectively ( 0.001). Furthermore, the number of mistakes in consecutive VR sessions was gradually reduced from 11 to 0. During supervised surgery, all the participants were able to perform at least part of an antromastoidectomy, and the mean TBC score was 3.57. There was a significant strong positive correlation between the individual results of the fifth VR session and the individual results of supervised surgery in the operating room (r = 0.89, 0.001).
Virtual reality for temporal bone training makes it possible to acquire surgical skills in a safe environment before performing supervised surgery. Furthermore, the individual final score of virtual antromastoidectomy training allows a prediction of the quality of performance in real surgery.
本文旨在分析虚拟现实（VR）乳突根治术模拟训练的结果，以及所获技能向实际颞骨手术的可转移性。
对一组10名医生进行前瞻性研究，包括五次VR模拟训练课程，随后进行实际颞骨手术。使用约翰霍普金斯医院编制的基于任务的检查表（TBC）评估操作质量。此外，在每次VR课程中，记录错误（并发症）的数量和类型。
在连续的VR课程中，TBC测量的操作质量显著提高。第一次和第五次课程的平均得分分别为1.84和4.27（<0.001）。此外，连续VR课程中的错误数量从11个逐渐减少到0个。在监督手术期间，所有参与者都能够至少完成部分乳突根治术，平均TBC评分为3.57。第五次VR课程的个人成绩与手术室监督手术的个人成绩之间存在显著的强正相关（r = 0.89，<0.001）。
用于颞骨训练的虚拟现实技术使在进行监督手术之前在安全环境中获得手术技能成为可能。此外，虚拟乳突根治术训练的个人最终得分可以预测实际手术中的操作质量。
