Insular glioma resection: operative strategies and clinical outcomes

This manuscript contains a review of insular glioma surgery, covering insular anatomy, operative approaches, intraoperative mapping, neuronavigation, diffusion tensor imaging tractography, intraoperative magnetic resonance imaging, fluorescence-guided surgery, and techniques for preserving eloquent cortex and perforating vessels during resection, summarizing current surgical strategies for maximizing extent of resection, while minimizing neurological morbidity and seeks to provide a reference for clinicians and researchers interested in insular glioma surgery.
