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.

“…Bubble wraps [18], parafilm [19], foliage leaves [20], and gauze [21,22] are commonly used for fundamental microsurgery training. Commercially available training cards with silicon tubes [22], synthetic vessels with polyurethane [3], polytetrafluoroethylene [23], and polyethylene [24,25] are useful models for advanced microsurgical training in attempt to reduce animal usage. Similarly, cryogenic rat or rabbit femoral vessels, carotid vessels, and aorta offer "off the shelf" microvascular anastomosis exercise from the "recycled parts" of the sacrificed animals [26].…”

“…Some authors proposed to use animal cadaver vessels perfused in vitro for microvascular training as legs vessels of slaughtered pigs (Steffens et al, 1992), chicken wing vessels Krishnan et al, 2004), porcine coronary arteries (Schoffl et al, 2006). Other authors described synthetic models to simulate the live vessels (Korber & Kraemer, 1989;Weber et al, 1997;Meier et al, 2004;Matsamura et al, 2009;Spetzer et al, 2011) and to reduce the number of animals required for microsurgical training. All these techniques are useful for microvascular anastomosis training but they are not able to simulate the anatomic conditions of the anastomosis in a patient and to improve the surgical anatomic knowledge of the residents.…”

. Learning surgical anatomy in the field of microsurgical reconstructive surgery. A new pedagogic method on human fresh cadavers. Int. J. Morphol., 32(2):678-683, 2014. SUMMARY:Microsurgical vascular anastomosis in reconstructive surgery learning is usually based on rat dissection. But this technique does not allow dissection of the flap, preparing of the recipient vessels training, and suturing in conditions as realistic as possible of the surgery. The aim of this study was to describe a technique of surgical anatomy learning on human fresh cadavers, easy to perform and to evaluate its pedagogic interest. In the first part of the study, six fresh cadavers have been dissected simulating 6 forearm flaps with growing difficulty. In the second part of the study, 30 residents in surgery were evaluated on their ability to recognize main anatomic structures and to perform microsurgical anastomosis, of forearm flaps anastomosed on facial vessels. Concerning the first part of the study, it has been possible to use this method in all cases. The second part of the study showed that all the residents performed the dissection of the flap with success. The main anatomic structures (origin of the radial and ulnar arteries, companion veins of radial artery) have been identified by all the residents. The cephalic vein, the median antebrachial vein and the superficial branch of the radial nerve have been identified by most of the residents. The lateral antebrachial cutaneous nerve has been identified by only 12 residents. The arterial anastomosis has been performed with success in most cases (11/15 dissections), and the venous anastomosis in only 5/15 dissections. Surgical anatomy learning in the field of microvascular reconstructive surgery on human fresh cadavers is possible, easy to organize in a anatomy department. This method has to be considered as a useful complement of microvascular anastomosis learning on rats.
