Skull base tumors. A critical appraisal and clinical series employing image guidance

Two of the most significant developments in neurosurgery over the past ten years have been the application of intraoperative navigational units and the widespread use of "skull base" surgical techniques. These developments have independently revolutionized the way in which neurosurgeons approach intracranial pathology. The combination of these two developments has had a profound effect in our clinical practice to improve outcome and extend our capabilities. This ability to see around the corner, "x-ray" vision as some have called it, provides an added measure of safety for the patient while allowing the surgeon to treat the lesion in a more aggressive fashion.
