目的 探讨数字建模结合3D打印模型在耳鼻咽喉科住院医师规范化培训中的应用效果。方法 选取2017年1月至2021年9月在中山大学附属第三医院耳鼻咽喉科进行住院医师规范化培训的42名学员为研究对象,采用随机数字表法将其分为试验组和对照组,每组21名学员。试验组学员采用数字建模结合3D打印模型的教学方式;对照组学员采用传统教学方式,以问卷调查和鼻窦CT阅片评分来评价教学效果。计数资料组间比较采用χ2检验,计量资料组间采用独立样本t检验。结果 试验组学员和对照组学员对教学的评价分别为(18.43±1.40)分和(12.43±1.21)分,试验组学员和对照组学员的阅片评价分别为(93.52±2.62)分和(81.43±2.27)分,差异均具有统计学意义(均P<0.001)。结论 采用数字建模结合3D打印模型的教学方式获得了学员的认可,有助于提高住培学员对鼻腔鼻窦解剖知识的理解和掌握。
Objective To investigate the application of virtual and 3D printing model in clinical standardized training of otorhinolaryngology residents. Methods Forty-two rhinologists residents in standardized training (from January 2017 to September 2021) were randomly divided into the experimental group and the control group. The experimental group were trained by virtual and 3D printing model, while adopting traditional training methods in the control group. Then the questionnaire and the image reading of nasal sinus CT were used to evaluate the training effect. The chi-square test was used for comparison among groups of counting data, and independent sample t-test was used for measurement data between groups. Results The questionnaire showed that the scores of the experimental group and the control group were (18.43±1.40) and (12.43±1.21) respectively. In the comprehensive evaluation of the image reading effect, the scores of the experimental group and control group were (93.52±2.62) and (81.43±2.27). These differences were all statistically significant (all P<0.001). Conclusions The training method of virtual modeling combined with 3D printing model has been recognized by the residents, which would greatly improve the understanding of anatomy knowledge of nasal cavity and paranasal sinuses.
