Within surgery, interactive media have previously been used to educate medical students and residents. Here, we develop and assess the efficacy of a novel surgical video atlas in teaching surgically relevant head and neck anatomy to medical students. A total thyroidectomy was recorded intraoperatively and subsequently narrated to develop a video atlas. Medical students were recruited and randomly assigned to one of the two interventions. One group was assigned to the video atlas, while the other was supplied with a traditional textbook atlas. Both groups underwent pre- and post- tests to evaluate anatomical knowledge and satisfaction. Thirty-seven students completed the study, with 18 students in the experimental group and 19 students as control. In the video atlas arm, mean pre and post-test scores were 57.2% and 84.5%, respectively. In the traditional textbook arm, the mean pre- and post-test scores were 55.3% and 76.51%, respectively. Students with the video atlas had a mean post-test score 8.07% points higher than those without (p = .035). Overall, students were significantly more satisfied with the surgical video atlas than with the standard traditional textbook. A surgical video atlas was shown to more effectively teach head and neck anatomy to medical students compared to standard textbook atlases.
在外科手术领域，交互式媒体此前已被用于培训医学生和住院医师。在此，我们开发并评估了一种新型手术视频图谱在向医学生传授与外科手术相关的头颈部解剖学知识方面的效果。术中记录了全甲状腺切除术的过程，并随后进行讲解以制作视频图谱。招募了医学生并将他们随机分配到两种干预措施之一。一组被分配使用视频图谱，而另一组则提供传统的教科书图谱。两组都进行了课前和课后测试，以评估解剖学知识和满意度。37名学生完成了研究，实验组有18名学生，对照组有19名学生。在视频图谱组，课前和课后测试的平均分数分别为57.2%和84.5%。在传统教科书组，课前和课后测试的平均分数分别为55.3%和76.51%。使用视频图谱的学生课后平均分数比未使用的学生高8.07个百分点（p = 0.035）。总体而言，与标准传统教科书相比，学生对手术视频图谱的满意度明显更高。与标准教科书图谱相比，手术视频图谱在向医学生传授头颈部解剖学知识方面更有效。
