Utilizing a 3D Printed Model of the Mediastinum to Teach Thoracic Anatomy to Medical Trainees

Three-dimensional (3D) printed anatomic models are increasingly being developed for medical education. The investigators sought to compare the efficacy of a 3D printed model of the mediastinum as a study tool with standard textbooks for teaching medical trainees thoracic anatomy. Participants were randomly assigned to either a lecture using a standard anatomy textbook or the same lecture along with a 3D printed model of the mediastinum. Participants took a timed pre-test and post-test, identifying 12 mediastinal structures on a prosected human cadaver. Independent and dependent t-tests were used to compare individual and group improvements respectively. A subjective assessment was also performed.
