数字化模型外科联合“病案”教学法培训模式在髁突肿瘤继发牙颌面畸形手术教学中的应用

Application of DMS Combined with CBT in the Specialist Training for Orthognathic Treatments of Condylar Tumors

目的:评价数字化模型外科(digital model surgery,DMS)联合“病案”教学法(case-based teaching,CBT)培训模式在髁突肿瘤继发牙颌面畸形手术教学中的应用价值。方法:将2019年1月至2020年12月招收的24名正颌外科专科规培医师随机分为实验组和对照组。实验组采用DMS联合CBT培训模式教学,而对照组采用传统带教模式。培训结束后采用理论考试、带教医师主观评价及问卷调查的方式评价两组手术教学效果。结果:实验组在理论考试得分、带教医师主观评价上都表现优于对照组,且差异具有统计学意义(P<0.05)。此外,问卷调查结果显示实验组规培医师的学习兴趣、自信心、满意度均高于对照组。结论:DMS联合CBT培训模式可以提高髁突肿瘤继发牙颌面畸形手术教学效果,增强规培医师对该疾病手术方式的理解,收获良好的培训效果。

Objective: This study aims to investigate whether digital model surgery(DMS) combined with case-based teaching(CBT) can improve residents’ learning efficacy in orthognathic treatments of condylar tumors. Methods: 24 orthognathic residents in standardized residency training program for medical trainees in China recruited from January 2019 to December 2020 were randomly assigned to the experiment group and the control group. The control group was provided with conventional training courses, while the experimental one was required to experience both DMS and CBT courses though out the process. At the end of the training courses, training effects of both groups were assessed by theoretical evaluation, feedback from instructors and questionnaire survey. Results: Both theoretical evaluation and feedback from instructors significantly improved after using DMS and CBT(P<0.05). The experimental group reported better results in learning interest, confidence and satisfaction compared with the control group. Conclusion: DMS combined with CBT is beneficial to the training for orthognathic treatments of condylar tumors.
