OBJECTIVE Neuroendoscopy is applied to various intracranial pathologic conditions. But this technique needs informations for the anatomy, critically. Neuronavigation makes the operation more safe, exact and lesser invasive procedures. But classical neuronavigation systems with rigid pinning fixations were difficult to apply to pediatric populations because of their thin and immature skull. Elec...
PURPOSE To evaluate the efficacy of surgery with neuronavigation compared to conventional neurosurgical treatment of epilepsy in terms of safety and seizure outcomes and to assess the quality of the evidence base of neuronavigation in this clinical context. METHOD Systematic review using the electronic databases of Cochrane, CRD, PubMed, Embase, SciELO and LILACS in Portuguese, English and Sp...
Objective: To investigate the effect of neuronavigation use on mortality in patients with glioblastoma. Methods: For each 26 that underwent neuronavigation-assisted supratotal resection for glioblastoma between 2018 and 2020, one patient without navigation was selected. Results: Radiographic radicality observed 35% cases surgery group 29% those conventional group. Absolute relative residual tum...
Objective To evaluate use of neuronavigation in interdisciplinary surgery for complicated tumors or trauma of the anterior or lateral skull base. Methods Neuronavigation image guidance was used in the surgical management of 40 patients, one with large orbital roof meningioma causing proptosis and visual deterioration, and the others with small cortical tumor, motor strip lesion and larger size ...
A Smartphone App to Assist Scalp Localization of Superficial Supratentorial Lesions--Technical Note.
BACKGROUND Neuronavigation is an established technology in neurosurgery. In parts of the world and certain circumstances in which neuronavigation is not easily available or affordable, alternative techniques may be considered. OBJECTIVE An app to assist scalp localization of superficial supratentorial lesions has been introduced, and its accuracy has been compared with established neuronaviga...
This paper presents the principle of multimodal and multi-informational neuronavigation as well as the data fusion environment we have developed for these techniques. Our fusion environment supports the planning step and includes registration, segmentation, 3D visualisation as well as data browsing and interaction tools. We provide a neuronavigation system with relevant information for the perf...
OBJECTIVE Part of the planning and performance of neurosurgery consists of determining target areas, areas to be avoided, landmark areas, and trajectories, all of which are components of the surgical script. Nowadays, neurosurgeons have access to multimodal medical imaging to support the definition of the surgical script. The purpose of this paper is to present a software environment developed ...
Neuronavigation and stereotaxy are techniques designed to help neurosurgeons precisely localize different intracerebral pathological processes by using a set of preoperative images (CT, MRI, fMRI, PET, SPECT etc.). The development of computer assisted surgery was possible only after a significant technological progress, especially in the area of informatics and imagistics. The main indications ...
Title: Effectiveness of endoscopic endonasal transsphenoidal surgery using a neuronavigation: Clinical results of 178 pituitary adenomas Background: The present study assesses endoscopic endonasal transsphenoidal surgery using neuronavigation for pituitary adenoma. Methods and findings: Data were analyzed from 178 consecutive patients with pituitary adenomas who underwent endoscopic endonasal t...
OBJECT The aim of this study was better preoperative planning and direct application to intraoperative procedures through accurate coregistration of diffusion-tensor (DT) imaging-based tractography results and anatomical three-dimensional magnetic resonance images and subsequent importation of the combined images to a neuronavigation system (functional neuronavigation). METHODS Six patients w...
