Basic surgical techniques in the resection of malignant gliomas.

Abstract

Although progress is being made in the imaging and medical therapy of malignant gliomas, surgery continues to play a central role in the management of these tumors. Surgery remains necessary for histological diagnosis and relief of mass effect upon adjacent neurological structures. Surgery also achieves cytoreduction of tumor mass, allowing more effective treatment of residual tumor volume. Recent technical advances have made the goal of gross total tumor resection safer and more readily achieved. Surgical techniques and adjuncts that aid the aggressive surgical resection of malignant gliomas will be reviewed.
