Long Island Gamma Knife® Center at South Nassau Communities Hospital

The Long Island Gamma Knife Center at South Nassau Communities Hospital offers Long Islanders access to state-of-the-art, non-surgical treatment of certain brain abnormalities, including malignant and benign tumors, acoustic neuromas, brain metastases, arteriovenous malformations (AVMs), meningiomas and functional disorders such as trigeminal neuralgia. Our Center is the only one on Long Island to use the state of the art Gamma Knife Perfexion™ to treat small-to-medium-sized abnormalities, particularly those that are difficult to treat or inaccessible using open surgical techniques.

The Gamma Knife is not a knife at all, but a revolutionary device that has become a well-accepted standard of care for the minimally-invasive surgical treatment of inaccessible or inoperable brain abnormalities. It fuses the skills of the physician with the revolutionary science of radiosurgery. Unlike traditional open surgery, Gamma Knife surgery involves no incision; it works by harnessing the power generated by 192 cobalt-60 radiation beams, converged on a precise target area of the brain. At the site where the beams converge, enough radiation is generated to ionize and destroy a tumor or lesion 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. Multiple lesions or tumors can typically be treated in a single session.

There is no bleeding, no risk of infection, and no lengthy hospital stay following treatment. In fact, most patients can return to their normal daily activities the day after Gamma Knife surgery. The Gamma Knife is backed by 30 years of clinical experience. It has been used by more than 600,000 patients worldwide and results have been documented in more than 3,000 peer-reviewed published clinical papers.
