How Intraoperative Tools and Techniques Have Changed the Approach to Brain Tumor Surgery

Abstract

Purpose of Review: Surgical treatment of brain tumors remains an integral part of a comprehensive treatment plan. Here, we review technological advances that have enhanced what surgeons are capable of doing within and outside the traditional operating room. Recent Findings: Extent of surgical resection has improved with the use of MRI and fluorescent dyes intraoperatively. Neurological injury during brain tumor surgery has decreased with appropriate use of neurophysiological monitoring. New operative scopes have enhanced ability of surgeons to visualize tissues during dissection. Laser interstitial therapy and radiation treatment have made possible the treatment of previously considered non-operable brain tumors in addition to replacing or serving as adjunct to surgical treatment of brain tumors. Summary: Surgery remains an important pillar in treatment of most brain tumors. Ongoing technological advances have augmented extent of what is possible in this realm.
