Initial Experience with Brain Mapping under Awake Craniotomy for Resection of Insular Gliomas of the Dominant Hemisphere
Background & Importance: Insular lobe is located at the depth of sylvian fissure and is hidden by frontal, temporal and parietal lobes in close vicinity of internal capsule and basal ganglia and adjacent to the speech centers in the dominant hemisphere. Thus, radical resection of insular gliomas can be even more difficult. Brain mapping techniques can be used to maximize the extent of...
متن کامل[Surgical anatomy of the insular cortex].
OBJECTIVE The objective of the study was to investigate the surgical anatomy of the insular cortex, morphology and vascularization of the insula and adjacent opercula in terms of transsylvian and transcortical approaches, and identification of the permissible anatomical boundaries for resection of glial tumors of the insula. MATERIAL AND METHODS The study was conducted on 18 anatomical specim...
متن کاملFunctional magnetic resonance imaging and optical imaging for dominant-hemisphere perisylvian arteriovenous malformations.
OBJECTIVE In this study, we developed an a priori system to stratify surgical intervention of perisylvian arteriovenous malformations (AVMs) in 20 patients. We stratified the patients into three categories based on preoperative functional magnetic resonance imaging (fMRI) language activation pattern and relative location of the AVM. METHODS In Group I (minimal risk), the AVM was at least one ...
متن کاملResection Probability Maps for Quality Assessment of Glioma Surgery without Brain Location Bias
BACKGROUND Intraoperative brain stimulation mapping reduces permanent postoperative deficits and extends tumor removal in resective surgery for glioma patients. Successful functional mapping is assumed to depend on the surgical team's expertise. In this study, glioma resection results are quantified and compared using a novel approach, so-called resection probability maps (RPM), exemplified by ...
متن کاملCurrent surgical management of insular gliomas.
The insula is a functionally and anatomically complex cortical structure that can be affected by both low-grade and high-grade gliomas. This complexity often prevents many neurosurgeons from attempting to surgically manage insular gliomas. This article reviews the anatomic and functional uniqueness of the insula and the surgical outcomes and lessons learned from previously reported surgical ser...
