Objectives Medical three‐dimensional (3D) printing, the fabrication of handheld models from medical images, has the potential to become an integral part of otolaryngology–head and neck surgery (Oto‐HNS) with broad impact across its subspecialties. We review the basic principles of this technology and provide a comprehensive summary of reported clinical applications in the field. Methods Standard bibliographic databases (MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, Web of Science, and The Cochrane Central Registry for Randomized Trials) were searched from their inception to May 2018 for the terms: “3D printing,” “three‐dimensional printing,” “rapid prototyping,” “additive manufacturing,” “computer‐aided design,” “bioprinting,” and “biofabrication” in various combinations with the terms: “ptolaryngology,” “head and neck surgery,” and “otology.” Additional articles were identified from the references of retrieved articles. Only studies describing clinical applications of 3D printing were included. Results Of 5,532 records identified through database searching, 87 articles were included for qualitative synthesis. Widespread implementation of 3D printing in Oto‐HNS is still at its infancy. Nonetheless, it is increasingly being utilized across all subspecialties from preoperative planning to design and fabrication of patient‐specific implants and surgical guides. An emerging application considered highly valuable is its use as a teaching tool for medical education and surgical training. Conclusions As technology and training standards evolve and as healthcare moves toward personalized medicine, 3D printing is emerging as a key technology in patient care in Oto‐HNS. Treating physicians and surgeons who wish to stay abreast of these developments will benefit from a fundamental understanding of the principles and applications of this technology.

“…However, due to limitations of cadaveric material, synthetic temporal bones have been developed for training such as the Pettigrew temporal bone with variable success [33]. There have been other non-virtual reality models that have been developed for temporal bone drilling, with different forms of validation [34][35][36][37][38].…”

Purpose of Review Simulation-based training is an integral component of surgical training. It allows practice of technical skills within a safe environment without compromising patient safety. This article seeks to review current virtual and non-virtual reality simulation models within the literature and review their validation status. Recent Findings Many simulation models exist within otolaryngology and are currently being used for education. New models are also continuously being developed; however, validity should be proven for the models before incorporating their use for educational purposes. Validity should be determined by experts and trainees themselves. Summary A validated simulation curriculum should be incorporated within the otolaryngology training programme. A curriculum based on the current training programme at our institution serves as an exemplar for local adoption.

“…This technology enables physician learners to practice these skills while lessening the danger to patients through the use of complex high fidelity models 29 . For example, multiple centers have reported data on 3D-printed temporal bones in the education of their trainees [29][30][31] . During implementation, participants were asked to qualitatively evaluate these training exercises in terms of realism, anatomical accuracy, utility, and efficacy.…”

Objective: Three-dimensional printing technology is being employed in a variety of medical and surgical specialties to improve patient care and advance resident physician training. As the costs of implementing three-dimensional printing have declined, the use of this technology has expanded, especially within surgical specialties. This article explores the types of threedimensional printing available, highlights the benefits and drawbacks of each methodology, provides examples of how three-dimensional printing has been applied within the field of otolaryngology -head and neck surgery, discusses future innovations, and explores the financial impact of these advances.Data Sources: Articles were identified from PubMed and Ovid Medline.Review Methods: PubMed and Ovid Medline were queried for English articles published between 2011and 2016, including a few articles prior to this time as relevant examples. Search terms included: three-dimensional printing, 3D-printing, otolaryngology, additive manufacturing, craniofacial, reconstruction, temporal bone, airway, sinus, cost, and anatomic models.Conclusions: Three-dimensional printing has been used in recent years in otolaryngology for preoperative planning, education, prostheses, grafting, and reconstruction. Emerging technologies include the printing of tissue scaffolds for the auricle and nose, more realistic training models, and personalized implantable medical devices. Implications for Practice:After accounting for the upfront costs of three-dimensional printing, its utilization in surgical models, patient-specific implants, and custom instruments can reduce operating room time and thus decrease costs. Educational and training models provide an opportunity to better visualize anomalies, practice surgical technique, predict problems that might arise, and improve quality by reducing mistakes.3
