Purpose of Review Recently, there has been an expansion of novel technologies in simulation training. The aim of this review was to examine existing evidence about training simulators in rhinology, their incorporation into real training programmes and translation of these skills into the operating room. The first part focuses on the virtual and augmented reality simulators. The second part describes the role of physical (i.e. non-computer-based) models of endoscopic sinus surgery. Recent Findings We learned that an ideal sinus surgery model would score highly in all standard measures of validity whilst maintaining an attainable cost. This is a challenging goal that is worthy of pursuit given that simulation training has been shown to be cost-effective option in other domains. Non-AR or VR models are attractive ways to fill gaps in simulation training whilst reducing compared with computer-based models. Summary In an era of improved computer technology and improved 3D printing, it will be increasingly important to focus on both the manufacture and validation process. One area that will benefit from further technological advancement is the realistic simulation of bleeding as this would obviate the need for animal models. Future studies on ESS simulation will also need to robustly demonstrate the validity of each model with the emphasis on the ability of a model to predict performance in operative environment.

“…Their printing methods and materials were compared to sheep femur for bony characteristics, which may not be a similar enough model to human temporal bone because sheep femur does not contain highly aerated bone segments like human petrous and mastoid temporal bone . 3D printed models also lack soft tissue, do not allow for simulation of bleeding during dissection, and like cadaveric temporal bones, the use of 3D printed models requires a specialized laboratory and significant clean‐up after use. The potential health risks associated with aerosolizing the printed material have yet to be determined.…”

“…Other than cadaveric bones, the two most commonly used simulation platforms reported in the literature are three‐dimensional (3D) printed models and virtual reality (VR) simulation platforms. Most manuscripts reporting use of temporal bone simulation revolve around resident training with an emphasis on anatomic understanding and technique development . Applications related to surgical assessment, as well as those applications with more direct patient impact, have yet to be explored .…”

Background Temporal bone surgery is a technically challenging and high‐risk procedure in an anatomically complex area. Safe temporal bone surgery emphasizes a consummate anatomic understanding and technique development that requires the guidance of an experienced otologic surgeon and years of practice. Temporal bone simulation can augment otologic surgical training and enable rehearsal of surgical procedures. Objectives The purpose of this article is to provide an updated review of temporal bone simulation platforms and their uses. Data Sources PubMed literature search. Search terms included temporal bone, temporal bone simulation, virtual reality (VR), and presurgical planning and rehearsal. Discussion Various simulation platforms such as cadaveric bone, three‐dimensional (3D) printed models, and VR simulation have been used for temporal bone surgery training. However, each simulation method has its drawbacks. There is a need to improve upon current simulation platforms to enhance surgical training and skills assessment, as well as a need to explore other clinically significant applications of simulation, such as preoperative planning and rehearsal, in otologic surgery. Conclusions There is no replacement for actual surgical experience, but high‐fidelity temporal bone models such as those produced with 3D printing and computer simulation have emerged as promising tools in otolaryngologic surgery. Improvements in the fidelity of both 3D printed and VR simulators as well as integration of a standardized assessment format would allow for an expansion in the use of these simulation platforms in training and assessment.

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.
