The present review explores the anatomical features of language-eloquent areas and the techniques and technologies developed to map cortical areas and distinguish tumour tissue from functional tissue.
Abstract
Glioma resection surgeries require balance between language functioning protection and maximal tumour removal. Surgical planning is key for the success of resection procedures and the techniques involved are often associated with cortical mapping and tissue differentiation. These techniques include direct electrical stimulation, stereo-electroencephalography, functional magnetic resonance imaging, diffusion tensor imaging, functional ultrasound, hyperspectral imaging and intraoperative optical imaging. The present review explores the anatomical features of language-eloquent areas and the techniques and technologies developed to map cortical areas and distinguish tumour tissue from functional tissue. The benefits and limitations of each technique are discussed, along with their intraoperative and preoperative uses. All techniques are discussed in the context of their effectiveness in the preservation of cortical areas responsible for language processing.
Over the last two decades, substantial progress has been achieved in basic tumour research. However, advances in the management of high-grade gliomas have remained limited compared with other oncological diseases. The improvement in clinical outcomes observed during this period has largely resulted from the integration...

Anterior temporal lobectomy is well standardized in epilepsy surgery, but its oncological application is less defined. Tumor-induced distortion of anatomical landmarks, proximity of eloquent cortex and white-matter tracts, and the need to balance maximal resection with functional preservation demand a reproducibl...

Image-guided minimally invasive neurosurgery has transformed the management of intracranial lesions by integrating advanced imaging, neuronavigation, stereotactic planning, intraoperative visualization, and reduced surgical corridors. The objective of this study was to analyze the anatomical precision, patient-selectio...

Purpose To evaluate the efficacy of functional neuronavigation combined with intraoperative fluorescein sodium in the operation of brain metastases. Patients and methods From January 2018 to December 2023, 80 patients with brain metastases were divided into observation and control groups based on using sodium fluoresce...

Simple Summary Surgeons removing brain tumors that spread from other cancers need a reliable way to see where the tumor ends and healthy brain begins. We tested narrow-band imaging (NBI), a light-based technique that highlights blood vessels without any drug, in a retrospective, exploratory study of 25 patients having...
Background. Glioma surgery requires balancing maximal tumor resection against preservation of neurological and cognitive function. Intraoperative direct electrical stimulation guides this balance but is invasive and not always feasible. Preoperative magnetoencephalography (MEG) can identify tumor regions with high func...
