Long Island Gamma Knife® at Mount Sinai South Nassau

Having treated over 2,300 patients to date, the Long Island Gamma Knife® at Mount Sinai South Nassau  opened in 2002 and remains the longest-running Gamma Knife program on Long Island. We use the Gamma Knife Perfexion™ to treat small-to medium-sized abnormalities, particularly those that are difficult to treat. This technology even allows our experts to reach areas of the brain that would otherwise be difficult to treat, including areas not safely accessible using traditional surgery.

The Gamma Knife is not a knife. Instead it provides blade-less surgery specifically designed for non-invasive procedures. Gamma Knife surgery provides pinpoint accuracy and allows the physician to target radiation on the precise area of the brain to destroy a tumor or other abnormal tissue deep within the brain. The beams are focused with such precision that radiation is delivered only to the target, sparing surrounding healthy tissue, blood vessels and nerves. Physicians can typically treat several areas of the brain in a single session, if necessary.

There is no bleeding, no risk of infection, and no lengthy hospital stay following treatment. Patients benefit from fast, painless treatment, often conducted in an outpatient surgical setting without the need for general anesthesia or even convalescence.

Types of conditions we treat with Gamma Knife technology:

  • Malignant tumors (cancers that can spread to other parts of the body)
  • Benign tumors (that do not spread to other parts of the body)
  • Acoustic neuromas (noncancerous growths that can affect hearing)
  • Arteriovenous malformations (AVMs, a tangle of abnormal blood vessels)
  • Functional disorders such as trigeminal neuralgia (a chronic condition that causes face pain)
