“…For instance, cartilaginous tissues for dissection and drilling needed a liquid coating to increase the physical strength of a structure created by BJ in contrast to the infiltrations of elastomeric resins meant to increase its flexibility. 27 Similarly, BJ was used for tumours in the context of surgical simulation, 26 arteries to practise transcatheter valve replacements, 17 as well as hepatic segments 50 and hearts 17 51 to teach human anatomy.…”

3D printing is a new technology in constant evolution. It has rapidly expanded and is now being used in health education. Patient-specific models with anatomical fidelity created from imaging dataset have the potential to significantly improve the knowledge and skills of a new generation of surgeons. This review outlines five technical steps required to complete a printed model: They include (1) selecting the anatomical area of interest, (2) the creation of the 3D geometry, (3) the optimisation of the file for the printing and the appropriate selection of (4) the 3D printer and (5) materials. All of these steps require time, expertise and money. A thorough understanding of educational needs is therefore essential in order to optimise educational value. At present, most of the available printing materials are rigid and therefore not optimum for flexibility and elasticity unlike biological tissue. We believe that the manipuation and tuning of material properties through the creation of composites and/or blending materials will eventually allow for the creation of patient-specific models which have both anatomical and tissue fidelity.

“…Plaster-based color 3D binder jetting is a technique able to produce the required multicolor models 7 . Whereas in its standard configurations only the surface of an object can be colored, herein a modified technique is described to ensure volumetric application of color to internal anatomical structures.…”

Three-dimensional (3D) printing technologies offer the possibility of visualizing patient-specific pathologies in a physical model of correct dimensions. The model can be used for planning and simulating critical steps of a surgical approach. Therefore, it is important that anatomical structures such as blood vessels inside a tumor can be printed to be colored not only on their surface, but throughout their whole volume. During simulation this allows for the removal of certain parts (e.g., with a high-speed drill) and revealing internally located structures of a different color. Thus, diagnostic information from various imaging modalities (e.g., CT, MRI) can be combined in a single compact and tangible object. However, preparation and printing of such a fully colored anatomical model remains a difficult task. Therefore, a step-by-step guide is provided, demonstrating the fusion of different cross-sectional imaging data sets, segmentation of anatomical structures, and creation of a virtual model. In a second step the virtual model is printed with volumetrically colored anatomical structures using a plaster-based color 3D binder jetting technique. This method allows highly accurate reproduction of patient-specific anatomy as shown in a series of 3D-printed petrous apex chondrosarcomas. Furthermore, the models created can be cut and drilled, revealing internal structures that allow for simulation of surgical procedures.

Object 3D printing technology has becoming more and more popular in medicine, we aim to describe the application experiences of 3D printing technology in endoscopic surgery for skull base tumors, with the assessment of 3D-printed models in skull base endoscopic surgery simulation and anatomy learning.Method Five patients with 3D-printed models were enrolled in our institution from October 2015 to March 2019. 5 individual models, created by different 3D printing methods and printing materials, were used to design the optimal surgical approach before surgery. Besides, the 3D-printed models were applied in endoscopic surgery simulation and anatomy learning. Likert scale questionnaires (1 indicating strongly disagree; 2, disagree; 3, neutral; 4, agree; and 5, strongly agree) were administered to 9 neurosurgeons in our institution to evaluate the application of 3D printed models. Result We successfully printed 5 cases of complex skull base tumor 3D models and performed endoscopic surgery with the help of information of the 5 3D-printed models. Evaluation of the Likert scores showed that model 4 which was printed by the mixed photosensitive resin material was the most conducive in surgery simulation and anatomy learning. The mean (standard deviation) 3D printing time is 16.3 (4.96) hours, and the mean (SD) printing cost is 4,500 (1183.22) RMB.Conclusion 3D printing technology has a high value in the application of endoscopic surgery for skull base tumors. The fast 3D printing time can satisfy the requirement of tight preoperative inspection time. Besides, the average price is acceptable for patients and clinical anatomy learning. The combination of the technology of 3D printing and the techniques of skull base endoscopy shows many unique advantages.
