摘　　要：目的开发一种数字化技术的耳郭再造模拟训练系统,并对系统的应用效果进行评估。方法2019年9月至2021年12月,哈尔滨医科大学附属第二医院整形外科研制了新型耳郭再造模拟训练系统。临床规范化培训学员36名(男15名、女21名,年龄22~27岁,平均23.1岁),分为试验组和对照组各18名,对模拟教学系统效果进行初步评估。结果试验组干预前后理论测试分数[8.00(4.75,11.25)比16.50(13.00,19.25)分,P<0.001];设计测试分数[2.00(0,4.25)比7.00(6.00,10.00)分,P<0.001]。对照组干预前后理论测试分数[5.50(3.75,12.25)比11.00(9.50,16.25)分,P<0.001];设计测试分数[1.00(1.00,2.25)比5.00(3.75,6.00)],P<0.001。试验组与对照组比较改善更明显,差异有统计学意义(P<0.001)。结论在自体肋软骨耳郭再造培训中,数字化技术新型耳郭再造模拟训练系统能辅助教师更系统地进行教学,效果较好。Objective To design and develop a digital auricle reconstruction simulation training system and to evaluate the application effect of the system.Methods Based on 3D reconstruction and 3D printing technology,a new auricle reconstruction simulation training system was designed and developed from September 2019 to December 2021.Thirty-six basic volunteers(including 15 males and 21 females,aged from 22 to 27 years,with mean 23.1 years)without auricle reconstruction(surgical clinical standardized training students)were selected and divided into two groups(experimental group and control group)for clinical teaching experiment,and the teaching effect of simulation system was preliminarily evaluated.Results Theoretical test scores before and after the intervention in the experimental group were 8.00(4.75,11.25)compared to 16.50(13.00,19.25),P<0.001;design test scores were 2.00(0,4.25)compared to 7.00(6.00,10.00),P<0.001.In the control group,theoretical test scores before and after the intervention were 5.50(3.75,12.25)compared to 11.00(9.50,16.25),P<0.001;design test scores were 1.00(1.00,2.25)compared to 5.00(3.75,6.00),P<0.001.The improvement in the experimental group compared to the control group was significantly more pronounced with a statistically significant difference(P<0.001).Conclusions This system can assist teachers in teaching more systematically in auricle reconstruction training with autologous costal cartilage,and the teaching effect is better.
