Abstract

Gurses, M.E., Basic Neuroanatomy Training Model Application Created with 3D Models of Brain White Matter Pathways, Augmented Reality and Virtual Reality Simulations, Hacettepe University Department of Neurosurgery, Ankara, 2023. Objective: The creation of an online and mobile basic neuroanatomy training application, which is planned to teach the three-dimensional relations of the structures of the brain with each other from 3D models of the gradually revealed dissections of cadaveric human brains, and its application to medical school students and neurosurgery residents. Method: Training was given with a total of 49 three-dimensional models, including 14 lateral faces, 8 medial faces, 11 cross-sectional axial, 9 sectional sagittal, and 7 sectional coronal. The training model created was applied online to 40 neurosurgery assistants, whose cadaveric training was disrupted during the Covid-19 pandemic and earthquake disaster, and to 200 medical school students via the augmented reality application. In order to determine the level of pre-training and to determine the level of realization of the learning objectives after the training, a personalized 10-question exam was held. After the training, a 4-point Likert-type scaled questionnaire with 18 questions was applied regarding the training content. Results: In the gradual white matter fiber dissection study; Superior Longitudinal Fascicle/Arcuate Fascicle Complex (SLF/AF), Middle Longitudinal Fascicle (OLF), Frontooccipital Fascicle (IFOF), Uncinate fasciculus, Extreme capsule, External capsule, Putamen, Globus pallidus, Claustrum, Internal capsule, Caudate, Thalamus, Tapetum, Optic tract, Insula, Operculum, Corona radiate, Sagittal stratum, Ventricular ependyma, Thalamus, Singular gyrus, Fornix, Choroid plexus, Forceps major, Anterior commissure, Corpus callosum, Choroid plexus, Callosal fibers and freely rotated brain sections in different planes and 3D models compatible with augmented reality and virtual reality that can be moved and viewed from different angles with various magnifications. 200 medical school students and 40 assistants used the training model created. This training model was rated by 200 medical students and 40 residents as significantly increasing neuroanatomy learning. Conclusion: The benefits of using cadaver studies and 3D models in basic neurosurgery and neuroanatomy training have been proven. In the literature review, it has been determined that no vi online and mobile application of 3D models has been transformed into a gradual training program. The 3D models of the brain created as a result of the study were brought to Hacettepe University Faculty of Medicine of education programs and literature for use in basic neuroanatomy and neurosurgery education in centers and times where cadaver access is limited (earthquake, epidemic, etc.).
