Gamma Knife® radiosurgery is a leading-edge technology that uses radiation instead of open surgery to shrink tumors or repair other brain abnormalities.

Its unique technology spares normal, healthy tissue because low-dose radiation is delivered via a circle of beams around the head, all of which 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. Some of the more common tumors include meningiomas, acoustic neuromas, and metastatic tumors.

The benefits of Gamma Knife surgery include no risk of anesthesia, no incision, no hair loss, short hospitalization, immediate return to pre-procedure activities, and minimal to no discomfort.

We perform Gamma Knife surgery at Northern Westchester Hospital in Mount Kisco, and where BSSNY neurosurgeon, Dr. Alain de Lotbinière, is co-director of its Gamma Knife Center.
