Update on the applications of neuronavigation in neurosciences

Introduction: the neuronavigation system is a technological advance whose role is to allow real-time visualization of intracranial structures, which are obtained from preoperative images and reconstructed in third dimension, which are projected through the screen. Objective: to characterize the advantages and disadvantages of neuroimaging and neuronavigation. Method: medical-scientific electronic databases such as MEDLINE, Pubmed, Clinical Key, Scopus and Web of Science involving certain articles of medical relevance, in addition to books recognized within the scientific community, for which we used the keywords "neurosurgery", "neuronavigation", whose search period was between 2018 and 2022. About 22 publications were collected of which 10 have been considered for the realization of this literature review. Results: the advent of this technology has served to perform several highly complex neurosurgical procedures in a safer and more precise way, including minimally invasive ones, improving the accuracy of the approach and reducing the risks of complications, which is why it plays a fundamental role in the neurosurgeon's accuracy while making the success of operations feasible with a lower risk. Conclusions: neuronavigation is a tool that considerably decreases surgical time, craniotomy dimensions and therefore decreases complications and lesions of adjacent structures, improving prognosis and decreasing sequelae in the patients studied.
