Basic techniques and points to notice in Glioma surgery

Abstract

“Maximal safe resection” is required for glioma surgery. Technological advances in intraoperative brain function and tumor location evaluation have led to a more aggressive approach to glioma resection while still maintaining functional preservation. However, basic neurosurgical techniques still play the most key role in obtaining “maximal safe resection”. Dissection of the fissure, sulcus, and cerebral vessel as well as unfolding the gyrus and lobe are important techniques to remove gliomas. When taking the biological characteristics of gliomas, especially their invasiveness, in mind, the extent of resection should be decided in view of the displaced vessels, neurotract, eloquent area, original site and spreading mode of the tumor. For neurosurgeons, the three main points to notice are: do not rely on surgical support systems and techniques, keep a clear operative view, and cultivate your surgical intuition.
