“…Related to this, the most important factor is the correct selection of materials which is related to the selection of the 3D printing process, printer, and the mechanical properties of the model [30]. Widely used 3D printing technologies and specially designed models allow students to study complex anatomical regions and areas that are difficult for them to comprehend, requiring various levels of expertise [31,32]. In the medical field, 3D printed models serve as a great visualization tool that can represent the anatomy of patients, with great potential in presurgical planning and surgery [33][34][35][36].…”

The choice of technique for the creation of a 3D digital human bone model from natural specimens has a critical impact on the final result and usability of the obtained model. The cornerstone factor in 3D modeling is the number of faces of polygon mesh, along with topological accuracy, as well as resolution and level of detail of the texture map. Three different techniques (3D scanning, photogrammetry, and micro-computed tomography) have been used to create a digital 3D model of the human zygomatic bone. As implementation and use of 3D models can be divided into three main categories—visualization, simulation, and physical replication to obtain a functioning model (implant or prothesis)—the obtained models have been evaluated by the density and topological accuracy of the polygonal mesh, as well as by visual appearance by inspecting the obtained texture map. The obtained data indicate that for biomedical applications and computer biomechanical simulation the most appropriate technique of 3D model obtainment is micro-computed tomography, in its turn for visualization and educational purposes, the photogrammetry technique is a more preferable choice.

BackgroundUnderstanding the complex three‐dimensional (3D) anatomy of the nasal cavity, paranasal sinuses, and skull base, is difficult but essential for otolaryngology trainees, especially for endoscopic techniques. There is no effective teaching tool at the junior resident or medical student level allowing visualization and manipulation of these structures in 3D.ObjectiveTo create an interactive 3D app modeling the sinus and skull base for use by junior trainees learning surgical anatomy.MethodsUsing Adobe Photoshop, Cinema 4D, and ZBrush, surgeon and medical illustration teams collaborated to develop a tool combining schematic representation of relevant anatomy with radiologic and endoscopic correlates. This was then incorporated into a web application. Twenty‐one junior residents and medical students were recruited to use the app, and pre‐and post‐app self‐assessments and experience surveys were conducted to assess didactic efficacy.ResultsWe created an online‐compatible fully manipulatable schematic 3D representation of the nasal cavity, paranasal sinuses, and anterior skull base that is capable of anatomic layering. This schematic is presented alongside representative de‐identified radiologic images and surgical principles with corresponding highlighted diagrammatic structures to demonstrate clinically relevant radiologic and endoscopic anatomy. There was a statistically significant improvement in anatomical knowledge in all 13 questions assessing didactic efficacy, with 85.7% of participants providing overall positive feedback.ConclusionsAcknowledging the didactic utility in an early validation study with junior trainees, this sinus anatomy teaching tool offers a low‐cost and highly accessible modality capable of demonstrating complex anatomical relationships to trainees learning sinus and endoscopic endonasal skull base surgery.
