Abstract

Neurosurgery is one of the most complex areas of Medicine, and the use of surgical simulation has the potential to reduce the learning curve and increase the efficiency of surgeons. The cadaveric model, considered the gold standard, has several risks and difficult access in our country. Thus, it is necessary to develop new systems that can reliably simulate the surgical environment. Expected results: development of a feasible and financially viable ultra-realistic physical and virtual reality system and demonstrate its applicability in neurosurgical education. Scientific and technological challenges: Several models, such as virtual reality with tactile feedback and ultra-realistic three-dimensional prototypes have been created, but there are still few models focused on skull base and temporal bone neurosurgery. The physical models will be made from neuroradiological exams, such as tomography and nuclear magnetic resonance, using silicone rubber combined with polymers in different concentrations and special resin for the reproduction of different tissues; the virtual reality models will be prepared with specialized technical assistance. The validation of the physical models will be by direct comparison with cadaveric dissections, by a neurosurgeon specialized in skull base surgery. The validation of virtual models in neurosurgical education will be based on courses given to volunteer students. These will be divided into two groups: control (conventional lectures) and test (conventional lectures + virtual training). The theoretical, practical performance and self-satisfaction of the participants will be compared. (AU)
