摘要
目的 探讨3D打印导板技术在神经外科颅脑肿瘤定位教学中的应用效果。方法 纳入进修医师40名作为研究对象,随机分为对照组和试验组,每组各20名。对照组采用传统教学方法,授课内容主要以颅脑解剖知识及体表解剖标志为主;试验组在传统教学的基础上加入了3D打印技术的教学内容,使其应用于颅脑肿瘤的定位。授课结束后,对两组学员实际的定位准确性进行比较,并且完成笔试内容,包括客观(理论考试)及主观(自我评价)两部分。结果 试验组定位的准确性高于对照组,两组肿瘤中心位置差分别为(4.3±1.2)mm和(10.5±3.8)mm,差异具有统计学意义(P=0.009);相对于对照组,试验组学员对肿瘤定位的信心更强,差异具有统计学意义(P=0.004)。结论 3D打印导板技术用于年轻医师肿瘤定位教学培训中,极大地提高了学员定位的准确性和自信心,减少了在实际手术中不必要的创伤。
Objective To explore the effect of 3D printing guide plate in the teaching of craniocerebral tumor localization in Neurosurgery.Methods 40 physicians engaged in advanced studies were selected as the research object and randomly divided into the control group and the experimental group,with 20 in each.In the control group,traditional teaching methods were used,and the teaching content mainly focused on knowledge of craniocerebral anatomy and body surface anatomy marks.The experimental group added the teaching content of 3D printing technology on the basis of traditional teaching,so that it can be applied to the localization of craniocerebral tumors.After the lecture,the actual positioning accuracy of the two groups of students was compared,and the written test content was completed,including objective(theoretical examination)and subjective(self-evaluation)parts.Results The accuracy of localization in the experimental group was significantly higher than that in the control group,and the difference of tumor center location was(4.3±1.2)mm,(10.5±3.8)mm respectively(P=0.009).Compared with the control group,students in the experimental group had significantly stronger confidence in tumor localization(P=0.004),and the difference was statistically significant.Conclusions The application of 3D printing guide plate technology in the teaching and training of tumor localization for young physicians can greatly improve the accuracy and confidence of students localization,and finally reduce unnecessary trauma in actual surgery.
