“…Training on artificial models has a lot of advantages compared to human or animal specimens, provided they imitate the real surgical situation as far as possible. For some ENT operations, e.g., temporal bone surgery, sinus surgery, or reconstruction of skin defects, such models exist and are used successfully [10][11][12]. However, there are no models described or available for training otoplasty.…”

Otoplasty for the correction of protruding ears is characterized by various techniques and a common and popular cosmetic procedure. For the surgeon, whether beginner or advanced, it is essential to understand the principles and master techniques for standard auricular deformities before applying further sophisticated methods, because a lot of complications and failures are caused by wrong indication and incorrect surgical techniques. The different surgical steps are best learned from teaching models. Therefore, we developed two different silicone models of protruding ears with moderate auricular deformities: one with conchal hyperplasia for the training of conchal resection, and one without antihelix for creating an antihelical fold by suturing technique, based on computed tomography scans of patients. The silicone ear models were evaluated during four standardized surgery courses for residents in otorhinolaryngology by 91 participants using specially designed questionnaires. Nearly all participants rated the training on the auricular models as very helpful (n = 51) or good (n = 31); the scores for the different techniques and properties of the models ranged from 2.0 to 2.6 in a range from 1 (very good) to 4 (inadequate). The good results demonstrate the possibility for learning different surgical otoplasty techniques with this newly designed teaching tool.

“…In the field of surgery, the potential for 3Dp models has been explored for advanced simulation training that could be patient-specific, incorporate pathology and can share compatibility with surgical implants (Kurenov et al, 2015;Maragiannis et al, 2015;Narayanan et al, 2015). Physical models for more advanced clinical skills such as femoral vessel access that is compatible with a pulse generator and can be detected using Doppler ultrasound (O'Reilly et al, 2016).…”

“…Simulations offer the capability to create realistic medical scenarios for surgical training procedures and provide space for errors without any risks to patients (Dimmick et al, 2007;Ganju et al, 2013;Issenberg and Scalese, 2008;Stan and Ingrid, 2012), especially in particular challenging procedures (Narayanan et al, 2015). Due to the importance of surgical skill development, the Accreditation Council for Graduate Medical Education in the United States now requires simulation-based training for general surgery residencies (Stan and Ingrid, 2012) and the three basic approaches to this training involve human and animal cadaveric specimens, digital and virtual reality, and synthetic physical 3D models (Ryan et al, 2016).…”

Recent expansions in the development and availability of three-dimensional printing (3Dp) have led to the uptake of this valuable and effective technology within the modern context of medical education. It is proposed that 3Dp is entirely appropriate for the creation of anatomical models for purposes of teaching and training due to the ability of this technology to produce accurate 3D physical representations based on a processed data set acquired from sources including magnetic resonance imaging (MRI) and computed tomography (CT). When investigating the currently available educational research with respect to 3Dp, it is important that the best evidence supporting the practical and theoretical benefits of this technology in teaching and training can be identified, while any obstacles to the effective implementation of 3Dp can also be determined. Here, literature describing recent primary research with respect to the capability and utility of 3Dp in anatomy and surgery have been explored in a narrative review. The impact on resources of implementing this technology within medical education have also been investigated. In order to emphasise wider applications in medicine, the role of 3Dp in medical practice and research have also been examined. To identify recent literature appropriate for this review published up to March 2017, suitable search terms were determined and applied using PubMed and results were judged against an established checklist. The research identified was then allocated with respect to the agreed topic areas of anatomy education, surgical training, medical usage and medical research. A student partnership approach was utilised for this review and the focus of the work was driven by undergraduate students in collaboration with anatomy and medical educators. Preliminary findings from this narrative review support the implementation of 3Dp in anatomy education and surgical training as a supplement to traditional learning approaches.

“…When asked to compare 3D digital models to physical models, users reported a better learning experience with the physical models over 3D computer-aided design (CAD) models and textbooks [17]. For those reasons, 3D printed anatomical models have already been used in training of surgeons [18][19][20][21][22][23][24][25][26][27][28][29]. As the use of 3D printers in hospital will become increasingly integrated to medical imaging, introducing this technology early in undergraduate training could help students familiarize themselves with the conversion of preoperative imaging data to CAD files and the printing of personalized surgical models [30].…”

Access to cadaveric specimens, which is dependent on donation and heavy equipment, is still a limiting factor in the study of anatomy. As there are many spatially challenging structures throughout the human body for which physical support is beneficial, new strategies are always needed to implement new interactive teaching techniques to help students more efficiently grasp the complex organization of the human body. In this report, the author reveals the use of rapid prototyping technology to create an innovative and anatomically accurate teaching tool to engage students and help them build threedimensional (3D) mental maps of the human heart. The model consists of polylactic acid (PLA) thermoplastic deposited layer by layer on a platform in a pattern that corresponds to a digital Standard Tessellation Language (.stl) file. Printing a hollow human heart with a 1:1 ratio was rapid (<5 hrs) and affordable (approximatively US$5 per model). Given access to the appropriate printable digital files, students could print their own model and could subsequently paint them appropriately to give them an anatomically correct representation. This studentcentered activity is an extension of the current anatomy coloring textbooks, with the benefit of building an accurate 3D representation of the human body.
