“…The questions were based on several previous studies to evaluate the role of other 3D printed models 7, 16 . Subjective questionnaires in this trial consisted of five parts, including enjoyment, learning efficiency, authenticity, attitude and intention to use, and used standard five-point Likert-scale to quantify responses (1-strongly disagree, 5-strongly agree with the statement).…”

Three-dimensional (3D) printed models represent educational tools of high quality compared with traditional teaching aids. Colored skull models were produced by 3D printing technology. A randomized controlled trial (RCT) was conducted to compare the learning efficiency of 3D printed skulls with that of cadaveric skulls and atlas. Seventy-nine medical students, who never studied anatomy, were randomized into three groups by drawing lots, using 3D printed skulls, cadaveric skulls, and atlas, respectively, to study the anatomical structures in skull through an introductory lecture and small group discussions. All students completed identical tests, which composed of a theory test and a lab test, before and after a lecture. Pre-test scores showed no differences between the three groups. In post-test, the 3D group was better than the other two groups in total score (cadaver: 29.5 [IQR: 25–33], 3D: 31.5 [IQR: 29–36], atlas: 27.75 [IQR: 24.125–32]; p = 0.044) and scores of lab test (cadaver: 14 [IQR: 10.5–18], 3D: 16.5 [IQR: 14.375–21.625], atlas: 14.5 [IQR: 10–18.125]; p = 0.049). Scores involving theory test, however, showed no difference between the three groups. In this RCT, an inexpensive, precise and rapidly-produced skull model had advantages in assisting anatomy study, especially in structure recognition, compared with traditional education materials.

“…This finding, corroborated by the results of a previous report, suggests that coloring of these structures was very helpful regarding the surgeons' training. 9 Reproducibility of bone hardness and tactile sensation analogous to real surgery may be one of the merits of 3D models compared to virtual simulators. 10,11 This issue was evaluated by the surgeons' assessment ( Table 2).…”

“…This technology enables physician learners to practice these skills while lessening the danger to patients through the use of complex high fidelity models 29 . For example, multiple centers have reported data on 3D-printed temporal bones in the education of their trainees [29][30][31] . During implementation, participants were asked to qualitatively evaluate these training exercises in terms of realism, anatomical accuracy, utility, and efficacy.…”

Objective: Three-dimensional printing technology is being employed in a variety of medical and surgical specialties to improve patient care and advance resident physician training. As the costs of implementing three-dimensional printing have declined, the use of this technology has expanded, especially within surgical specialties. This article explores the types of threedimensional printing available, highlights the benefits and drawbacks of each methodology, provides examples of how three-dimensional printing has been applied within the field of otolaryngology -head and neck surgery, discusses future innovations, and explores the financial impact of these advances.Data Sources: Articles were identified from PubMed and Ovid Medline.Review Methods: PubMed and Ovid Medline were queried for English articles published between 2011and 2016, including a few articles prior to this time as relevant examples. Search terms included: three-dimensional printing, 3D-printing, otolaryngology, additive manufacturing, craniofacial, reconstruction, temporal bone, airway, sinus, cost, and anatomic models.Conclusions: Three-dimensional printing has been used in recent years in otolaryngology for preoperative planning, education, prostheses, grafting, and reconstruction. Emerging technologies include the printing of tissue scaffolds for the auricle and nose, more realistic training models, and personalized implantable medical devices. Implications for Practice:After accounting for the upfront costs of three-dimensional printing, its utilization in surgical models, patient-specific implants, and custom instruments can reduce operating room time and thus decrease costs. Educational and training models provide an opportunity to better visualize anomalies, practice surgical technique, predict problems that might arise, and improve quality by reducing mistakes.3
