“…Because the middle ear is hidden inside the temporal bone and has limited accessibility, several strategies have been developed to visualize its anatomy (Tschabitscher and Klug, ). Due to these difficulties, to date, simulations have gained increasing popularity in otolaryngology, especially for teaching the surgical anatomy of the middle ear and procedures used to treat it (Javia and Deutsch, ; Javia and Sardesai, ), including computer‐based simulations (Abou‐Elhamd et al, ; Clifton et al, ; Francis et al, ), problem‐based learning (Abou‐Elhamd et al, ), simulations using three‐dimensional synthetic models (Mills and Lee, ; Bakhos et al, ; Rose et al, ; Barber et al, ; Luu et al, ; VanKoevering and Malloy, ) and even animal models (Anschuetz et al, ). Similar results have been described between virtual and cadaveric temporal bone dissections regarding the acquisition of surgical skills in the middle ear region (Wiet et al, ; Andersen, Foghsgaard et al, ).…”

Teaching methodologies for the anatomy of the middle ear have not been investigated greatly due to the middle ear's highly complex structure and hidden location inside of the temporal bone. The aim of this randomized study was to quantitatively compare the suitability of using microscope-and endoscope-based methods for teaching the anatomy of the middle ear. We hypothesize that the endoscopic approach will be more efficient compared to the microscopic approach. To answer the study questions, 33 sixth-year medical students, residents and otorhinolaryngology specialists were randomized either into the endoscopy or the microscopy group. Their anatomical knowledge was assessed using a structured anatomical knowledge test before and after each session. Each participant received tutoring on a human cadaveric specimen using one of the two methods. They then performed a hands-on dissection. After 2-4 weeks, the same educational curriculum was repeated using the other technique. The mean gains in anatomical knowledge for the specialists, residents, and medical students were +19.0%, +34.6%, and +23.4%, respectively. Multivariate analyses identified a statistically significant increase in performance for the endoscopic method compared to the microscopic technique (P < 0.001). For the recall of anatomical structures during dissection, the endoscopic method outperformed the microscopic technique independently of the randomization or the prior training level of the attendees (P < 0.001). In conclusion, the endoscopic approach to middle ear anatomy education is associated to an improved gain in knowledge as compared to the microscopic approach. The participants subjectively preferred the endoscope for educational purposes. Anat Sci Educ 12: 507-517.

“…This research has highlighted the potential for 3D printing to equally contribute to the development of competency in fetal and early childhood surgery, particularly as a high skill field of surgery, and where the opportunities for skills enhancement may be very limited. There are examples already where the use of printed anatomical structures in surgical training has been explored for pediatric surgery for cleft palate pathologies by authors of the current study (Lioufas et al, ), and developmental abnormalities of the ear, where surgery may involve both soft and hard tissues and close proximity to facial nerves (Barber et al, ). With access to digital data spanning a broad spectrum of fetal ages, the underlying data developed in the present study can be translated into several different printed formats, including multimaterial prints and 3D print‐guided multimaterial simulators for practicing fetal surgery on 3D prints at appropriate stages of human development, as has been done for neurocranial surgical simulation (amongst other applications) (Waran et al, ; Ryan et al, ; Tai et al, ).…”

The practical aspect of human developmental biology education is often limited to the observation and use of animal models to illustrate developmental anatomy. This is due in part to the difficulty of accessing human embryonic and fetal specimens, and the sensitivity inherent to presenting these specimens as teaching materials. This report presents a new approach using three-dimensional (3D) printed replicas of actual human materials in practical classes, thus allowing for the inclusion of accurate examples of human developmental anatomy in the educational context. A series of 3D prints have been produced from digital data collected by computed tomography (CT) imaging of an archived series of preserved human embryonic and fetal specimens. The final versions of 3D prints have been generated in a range of single or multiple materials to illustrate the progression of human development, including the development of internal anatomy. Furthermore, multiple copies of each replica have been printed for large group teaching. In addition to the educational benefit of examining accurate 3D replicas, this approach lessens the potential for adverse student reaction (due to cultural background or personal experience) to observing actual human embryonic/fetal anatomical specimens, and reduces the potential of damage or loss of original specimens. This approach, in combination with ongoing improvements in the management and analysis of digital data and advances in scanning technology, has enormous potential to allow embryology students access to both local and international collections of human gestational material.

“…Most models are inexpensive, easily made and reproducible [25][26][27][28]. Other physical otology models are also available including 3D models for mastoidectomy, stapedectomy and various other middle ear surgeries [29][30][31][32]. Cadaveric temporal bone dissection has been used for mastoidectomy training for many years with high validity [14,15].…”

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.
