混合现实技术在口腔颌面-头颈肿瘤规范化培训教学中的应用

目的 探讨混合现实技术（mixed reality，MR）在口腔颌面-头颈肿瘤规范化培训教学中的应用效果。方法 将在颌面肿瘤科接受住院医师规范化培训的20名医师分为两组，分别采用MR教学（试验组）及传统带教（对照组）。教学效果采用理论技能考试+问卷调查方法进行评价。采用SPSS 24.0进行t检验和Wilcoxon秩和检验。结果 试验组理论考核成绩（85.30±3.59）优于对照组（80.20±5.63），差异有统计学意义（t = 2.41，P = 0.027）；试验组技能考核成绩（89.20±5.07）优于对照组（82.30±6.36），差异有统计学意义（t = 2.68，P = 0.015）。问卷结果显示，MR教学使学员易于掌握头颈解剖知识与手术操作技巧，有助于活跃课堂氛围及师生间的互动交流，提高学员的学习兴趣。MR教学组学员对教学效果更为满意，且推荐该教学法用于口腔颌面-头颈肿瘤培训教学。结论 MR教学能提高学员对头颈解剖知识与手术操作技巧的理解与掌握，并增强学员的学习兴趣，取得良好的教学效果，在口腔颌面-头颈肿瘤规范化培训教学中具有重要的应用价值。

Application of mixed reality in standardized resident training on oral and maxillofacial-head and neck tumor surgery

Objective To evaluate the effect of mixed reality (MR) in the standardized resident training on oral and maxillofacial-head and neck tumor surgery.Methods Twenty resident doctors, who received standardized training in the department of maxillofacial oncology of our hospital, were randomly divided into experimental group and control group. The MR teaching method was used in the experimental group, while the traditional teaching method was used in the control group. The teaching effect was evaluated by theoretical and operational tests and a questionnaire survey. Statistical analysis was performed with the SPSS 24.0 software. Statistical comparisons were performed by the Students'' t-test or the Wilcoxon rank correlation test.Results The theoretical test results showed that the scores of the experimental group were significantly higher than those of the control group (85.30±3.59 vs. 80.20±5.63, t = 2.41, P = 0.027). The operational test results showed that the scores of the experimental group were significantly higher than those of the control group (89.20±5.07 vs. 82.30±6.36, t = 2.68, P = 0.015). The questionnaire survey results showed that the MR teaching helped to easily acquire the knowledge of head and neck anatomy and operation skills. Besides, the doctors in the experimental group were more active and glad to communicate with others than those in the control group. In addition, the MR teaching method improved the learning interest of doctors. The doctors in the experimental group were more satisfied with the teaching effect than those in the control group, and they recommended that the MR teaching method be used in clinical training and teaching on oral and maxillofacial-head and neck tumor surgery.Conclusion MR teaching can help doctors understand and master the knowledge of head and neck anatomy and operation skills and improve their learning interest, achieving a good teaching effect, so it has important application value in the standardized resident training on oral and maxillofacial-head and neck tumor surgery.
