Figure 1: Harvey Cushing is the father of modern neurosurgery. His contributions paved the way for the establishment of the safety of brain tumor surgery in the face of critics.

Craniotomy techniques for brain tumor surgery have evolved immensely because of advances in imaging and microsurgical techniques. The development of flexible operative corridors, cortical and subcortical mapping, and magnetic resonance imaging (MRI) navigation have all enhanced the ability of the surgeon to resect tumors that were previously deemed inoperable.

With these technological advancements, the emphasis on simply minimizing mortality has shifted toward minimizing morbidity while also achieving maximal resection to provide an optimal outcome for patients.

In this chapter, I review the general principles of brain tumor surgery. The specific tenets for resection for each pathology are covered in the...
