Although the name implies the use of a surgical incision, the Gamma Knife® “blades” are actually highly focused, low-dose radiation beams used to shrink tumors or repair other brain abnormalities.
These beams zero in on the target but spare the surrounding, healthy tissue. These beams all converge at a specific point to deliver a concentrated blast of radiation to the target. Unhealthy cells slowly die, stabilizing or shrinking the tumor or correcting other conditions.
Gamma Knife® surgery is extremely effective in treating malignant and benign tumors, vascular abnormalities, and functional disorders (such as trigeminal neuralgia). Additional benefits include no use of anesthesia and it’s accompanying problems, no incision, no hair loss, short hospitalization, immediate return to pre-procedure activities, and minimal discomfort.
