“…12,18 Nonetheless, based on the clear advantages of teaching surgery through simulation, we created the S.I.M.O.N.T., especially designed for endoscopic training. 14,24 Similarity between the model and the human brain can be attested to in the pictures (Figs. 4 and 5) and videos.…”

“…1). 14,24 Silicon and fiberglass molds in the shape of the cerebral ventricles constitute the basic structure of the neuroendoscopic module trainer. An artist completes the setup by setting intraventricular structures, such as the choroid plexus and blood vessels, as well as pathological conditions, such as tumors and cysts.…”

“…2,4,5,7,8,[10][11][12][14][15][16][22][23][24] Unfortunately, financial, technical, and operational obstacles more often limit their application. Thus, anatomical models built from a myriad of materials 2,14,16,24 and using computational and artistic techniques 12 have become an interesting option in simulating endoscopic procedures with good accuracy at reasonable costs.…”

Object Ideal surgical training models should be entirely reliable, atoxic, easy to handle, and, if possible, low cost. All available models have their advantages and disadvantages. The choice of one or another will depend on the type of surgery to be performed. The authors created an anatomical model called the S.I.M.O.N.T. (Sinus Model Oto-Rhino Neuro Trainer) Neurosurgical Endotrainer, which can provide reliable neuroendoscopic training. The aim in the present study was to assess both the quality of the model and the development of surgical skills by trainees. Methods The S.I.M.O.N.T. is built of a synthetic thermoretractable, thermosensible rubber called Neoderma, which, combined with different polymers, produces more than 30 different formulas. Quality assessment of the model was based on qualitative and quantitative data obtained from training sessions with 9 experienced and 13 inexperienced neurosurgeons. The techniques used for evaluation were face validation, retest and interrater reliability, and construct validation. Results The experts considered the S.I.M.O.N.T. capable of reproducing surgical situations as if they were real and presenting great similarity with the human brain. Surgical results of serial training showed that the model could be considered precise. Finally, development and improvement in surgical skills by the trainees were observed and considered relevant to further training. It was also observed that the probability of any single error was dramatically decreased after each training session, with a mean reduction of 41.65% (range 38.7%–45.6%). Conclusions Neuroendoscopic training has some specific requirements. A unique set of instruments is required, as is a model that can resemble real-life situations. The S.I.M.O.N.T. is a new alternative model specially designed for this purpose. Validation techniques followed by precision assessments attested to the model's feasibility.

“…The development of alternative realistic training methods is vital (Cover figure). The challenge is to provide not only realistic simulation of various pathologies but also standardized training milestones that allow a gradual progression in technical difficulty in concert with objective assessments of performance [61].…”

“…They also provide the opportunity to obtain CT and MRI imaging to incorporate imageguided navigation into the training program [6]. Moreover, there is the possibility of developing various surgical environments (tumor appearance, consistency, bleeding, cystic content) that require the practice of different tasks with more realism and unquestionable safety [6,61]. A very important feature is the potential for high-fidelity haptic feedback that is not thus far supported by computer models.…”

It is increasingly apparent that the standards for surgical training are shifting from time-based to criterion-based parameters that emphasize obtaining and maintaining competencies [24]. The formation of a surgeon demands significant dedication and effort, in addition to time [54]. Current, wellestablished methods of surgical training are being challenged as the environment becomes increasingly competitive and litigious with greater scrutiny of patient outcomes [14,17,40,44,50]. In order to increase patient safety and improve treatment outcomes, several strategies such as problem-based learning and objective structured clinical examinations have promoted the development of new curricula in surgical education [13,15,35,51,52].Some of these changes have been driven by events in the 1980s and 1990s such as medical misconduct and overworked, unsupervised resident staff that contributed to patient morbidity and mortality. This also coincided with a growing medical malpractice crisis. As a result, regulatory bodies began to initiate new standards of work hour restrictions and supervision for residents in training. The New York Health Code of 1989 compiled regulations restricting resident work hours (80 h per week) and one day free a week and placed limits on the number of calls [24,32]. Concerns arose about the long-established methods of training surgical residents, and solutions were sought to reduce preventable errors and perioperative complications [24,9].The airline industry, with the development of flight simulators and pilot coaching methods, proved to be an excellent precedent for innovation in surgical education. Many surgical educators believe such methods are keys to accelerating the acquisition of fundamental skills and the rate of performance improvement among surgical residents. A Yale University study demonstrated that criterion-based simulator training decreased operating time by 30 % and operative errors by 85 % [47,48].
