“…The advantages of using prototypes include portability, since they allow trainees' movements to different locations, and the possibilities of commercialization and wide distribution. A comparison of the 3D approach and animal and cadaver models highlights ethical discussions, workspace limitations, acquisition difficulties, and biological risks [32,41]. Furthermore, cadaver models/pieces have limited availability and incur high costs.…”

“…Print systems facilitate the cost-effective production of custom objects from easily manageable digital data. These systems have already been successfully applied in various fields of otorhinolaryngology, which has enabled the creation of objects that have significant geometric complexity and are customized for surgical planning and training [32,42].…”

“…In addition, challenging situations and anatomies are reported in the literature, for instance, sialendoscopy training. Canzil et al [32] reported the efficiency of providing training using this technique, which could simulate even salivary duct tampons, and specified their broad ramifications [32].…”

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.

“…Currently, material jetting, material extrusion and vat photopolymerization are commonly used in direct 3D printing methods. Material jetting, represented by Polyjet technology, is the most popular option among them [ 2 , 68 , 69 , 70 ] because of the best multi‐material and multi‐color printing ability of it. Polyjet allows for easy and precise control to the mechanical properties of organ model by using photopolymers and resins (e.g., TangoPlus series form Stratasys) with various hardness and elasticity.…”

Physical organ models are the objects that replicate the patient-specific anatomy and have played important roles in modern medical diagnosis and disease treatment. 3D printing, as a powerful multi-function manufacturing technology, breaks the limitations of traditional methods and provides a great potential for manufacturing organ models. However, the clinical application of organ model is still in small scale, facing the challenges including high cost, poor mimicking performance and insufficient accuracy. In this review, the mainstream 3D printing technologies are introduced, and the existing manufacturing methods are divided into "directly printing" and "indirectly printing", with an emphasis on choosing suitable techniques and materials. This review also summarizes the ideas to address these challenges and focuses on three points: 1) what are the characteristics and requirements of organ models in different application scenarios, 2) how to choose the suitable 3D printing methods and materials according to different application categories, and 3) how to reduce the cost of organ models and make the process simple and convenient. Moreover, the state-of-the-art in organ models are summarized and the contribution of 3D printed organ models to various surgical procedures is highlighted. Finally, current limitations, evaluation criteria and future perspectives for this emerging area are discussed.

“…На сучасному етапі розвитку медичної науки неможливо вирішити проблеми зниження перинатальної захворюваності та смертності без поглибленого вивчення періодів ембріогенезу і раннього фетогенезу. Враховуючи надзвичайну значимість останніх для практичної медицини, їхній визначальний вплив на подальший розвиток плода та новонародженого, нами було опубліковано роботи [1][2][3][4] з висвітлення певних закономірностей пренатального морфогенезу і становлення топографії піднижньощелепної слинної залози (ПНЩСЗ) людини. Пізнання закономірностей становлення будови і топографії органів і систем організму людини має важливе значення для тлумачення істинного напрямку процесів органогенезу, механізмів нормального формоутворення органів, вини-кнення анатомічних варіантів та природжених вад [5].…”

Knowledge of the patterns of the formation of the structure and topography of organs and systems of the human body is important for the interpretation of the true direction of the processes of organogenesis, the mechanisms of normal morphogenesis of organs, the emergence of anatomical variants and congenital defects. The interest in continuing the research was initiated by the buildup of an integrative approach in scientific developments, which, together with the doctrine of the individual anatomical variability of organs, systems and the shape of the human body, is the foundation of medicine. The next movement in this direction is the study of the variability of the shape of the submandibular strait of the human submandibular salivary gland during intrauterine development. Using the methods of macro-copy, microscopy, graphic and plastic reconstruction, fine preparation under the control of a binocular loupe, morphometry on 111 objects (60 before a person's fetus 7-12 weeks of intrauterine development and 51 fetuses of 4-10 months of intrauterine development were studied Variants of the form of the submandibular strait and the frequency of its manifestations in prenatal and human fetuses are from the rudiment of the tongue. At the beginning of the prefetal period of human ontogenesis, the rudiment of the gland increases significantly and takes the form of a continuous epithelial cord, which is represented by a large number of dividing cells. during the prefetal period with the rudiment of the submandibular duct of the submandibular salivary gland, a number of regular sequential changes occur: 1 – the formation of numerous epithelial cords of the II, III, IV order, as dichotomous branches from the main (main) epithelial anlage, 2 – the formation of a cavity (canal ) in the main epithelial bud and its ramifications of the II-IV order; 3 – the concentration of mesenchymal cells surrounding the epithelial cords (the formation of the mesenchymal part of the submandibular strait of the submandibular salivary gland) with its clear separation from adjacent tissues. In the group of objects of study, most often (76 cases, or 68.47%) there is a direct form of the submandibular ducts; the arcuate variant of the form of the submandibular ducts is almost three times less (26 cases, or 23.42%); as a variant of the form – the S-shaped form of the submandibular duct – was observed even less often (9 cases, or 8.11%).
