O uso da impressão tridimensional aplicado na neurocirurgia: uma revisão sistemática

Abstract

In the field of neurosurgery, 3D printing has driven significant advances, especially because many of the conditions treated involve complex anatomical structures that are difficult to visualize directly. Therefore, neuroimaging has become a fundamental tool, increasingly integrated into the processes of diagnosis, planning, and execution of surgeries. This study aims to describe the benefits of using three-dimensional printing applied to neurosurgery. This research consisted of a systematic review following the PRISMA guidelines, effectively seeking to answer the guiding question: What are the benefits of using three-dimensional printing applied to neurosurgery? The search was conducted in the ScienceDirect and PubMed databases, considering articles published between 2021 and 2025, in English and Portuguese, directly related to the topic. Duplicate articles, those not meeting the temporal or objective criteria, as well as reviews, editorials, letters, abstracts, and summaries were excluded. Initially, 423 articles were found, and after duplicates were removed and criteria applied, 10 articles composed the final analysis. The main findings show that 3D printing favors safer and more precise interventions by enabling faithful reproduction of complex anatomical structures, personalization of surgical strategies, and production of customized devices. Furthermore, it reinforces its role as a supportive tool for professional training, promoting advances in surgical planning, simulation, and medical education, with the potential to reduce intra- and postoperative complications and improve clinical outcomes.
