“… 3 Multiple 3D-printed models have been developed as an inexpensive and high-fidelity alternative to cadaveric specimens for simulating mastoidectomy. 4 - 7 Because of the complex relationships of microscopic structures in a small space, 3D printing of the middle ear is more challenging. Although 3D models have been developed for otoendoscopic middle ear surgical training, none have included the detailed middle ear anatomy required for anatomic teaching.…”

Mastery of ear anatomy and otologic surgical skills is challenging for trainees, and educational resources are limited. Advancements in 3-dimensional (3D) printing have enabled the construction of complex microscopic models. Otoendoscopy provides excellent visualization and has been shown to enhance anatomic learning. Our aim was to develop a 3D model of the middle ear and external auditory canal using computed tomography images of a pediatric temporal bone for use with otoendoscopes. Resulting models are life sized, anatomically accurate, and allow for identification of relevant middle ear structures. Forty-six trainees were recruited for a pilot study and randomized to study using the model or standard resources. There were no differences in pretest, posttest, or 1-week posttest performance between groups; however, trainees assigned to the model reported higher prospective interest, satisfaction, and subjective improvement. This model may be used with otoendoscopes for anatomic and surgical training and represents an advancement in otologic surgical simulation.

“…In the field of otorhinolaryngology, surgical simulations have been successfully used to train practitioners in a series of procedures that generally encompass all subareas, including sinus surgery, peritonsillar abscess drainage, myringotomy tube placement, and mastoidectomy. Many believe that these simulations will soon become sufficiently advanced for use in standardized tests and certification [4].…”

PurposeThe progressive expansion of the technology that facilitates the development of three-dimensional (3D) printing within the field of otorhinolaryngology has opened up a new study front in medicine. The objective of this study is to systematically review scientific publications describing the development of 3D models having applications in otorhinolaryngology, with emphasis on subareas with a large number of publications, as well as the countries in which the publications are concentrated. Methods In this literature review, specific criteria were used to search for publications on 3D models. The review considered articles published in English on the development of 3D models to teach otorhinolaryngology. The studies with presurgical purposes or without validation of the task by surgeons were excluded from this review. Results This review considered 39 articles published in 10 countries between 2012 and 2021. The works published prior to 2012 were not considered as per the inclusion criteria for the research. Among the 39 simulators selected for review, otology models comprised a total of 15 publications (38%); they were followed by rhinology, with 12 (31%); laryngology, with 8 (21%); and head and neck surgery, with 4 publications (10%). Conclusion The use of 3D technology and printing is well established in the context of surgical education and simulation models. The importance of developing new technological tools to enhance 3D printing and the current limitations in obtaining appropriate animal and cadaver models signify the necessity of investing more in 3D models.

“…According to recent studies, 3D printing could enable the implementation of a more affordable and realistic SBT tool [6,7]. Indeed, many surgical specialties have developed and validated anatomical models to be used in their training curricula [8][9][10][11]. However, no 3D-printed simulation model has been designed specifically for HSBA.…”

Development and Learner-Based Assessment of a Novel, Customized, 3D Printed Small Bowel Simulator for Hand-Sewn Anastomosis Training

Hand-sewn bowel anastomosis (HSBA) is an essential skill for surgical residents to learn, as it is used in numerous surgical procedures. However, the opportunities to practice this skill before attempting it on patients are limited. Practice on simulators can help improve this technique, but there is a paucity of realistic, cost-efficient simulators for the acquisition of HSBA skills. This technical report describes the development of our simulator that consists of a small bowel manufactured from silicone and a 3D-printed clamp system to hold the bowel in place. Our simulator was co-designed by a clinical team of surgeons and then assessed for perceived acceptability and effectiveness by 16 junior residents in various surgical specialties at our faculty. A majority of the learners rated our simulator to be a good or very good learning tool for HSBA, although they suggested some minor improvements.Overall, our silicone small bowel model appears to be an effective and inexpensive way to acquire this surgical skill.
