Why choose CHS?

Advanced Treatments and Procedures

Our neuroscience team performs both minimally invasive and surgical procedures, including:

  • Aneurysm clipping
  • Aneurysm coiling
  • Craniotomy for trauma
  • Craniotomy for tumor resection
  • Transphenoidal pituitary tumor resection
  • Vascular malformations
  • Stereotactic radiosurgery (A minimally invasive surgery that allows for 3D imaging to locate and treat small targets in the brain)
  • Intraoperative navigation
  • Minimally invasive endoscopic techniques

Our team specializes in treating diseases and disorders of the brain, including:

  • Arteriovenous malformation (AVM)
  • Brain metastasis
  • Brain swelling
  • Brain tumors
  • Cerebrospinal fluid leaks (CSF)
  • Head traumas
  • Hydrocephalus
  • Infections
  • Pituitary tumors
  • Trigeminal neuralgia

Advanced Technologies

Our hospitals feature the latest and most advanced technology, including:

  • Good Samaritan Hospital (West Islip, NY) uses intraoperative navigation, brain tractography, and stereotactic radiosurgery. These unique technologies allow neurosurgeons to remove brain tumors with maximal precision and minimal invasiveness. They also offer outpatient radiosurgery procedures without opening the patient's head and without applying a frame to stabilize the patient's head.
  • St. Catherine of Siena Medical Center (Smithtown, NY) uses Airo Mobile Intraoperative CT, which allows surgeons to perform more minimally invasive procedures and provides the option of brain and spine surgery to patients who might not benefit from open surgery. Read more about the Airo, including a patient success story.
  • St. Francis Hospital (Roslyn, NY) uses Excelsius GPS™, a revolutionary robotic navigation system for minimally invasive neurosurgery. The high-tech spinal GPS system streamlines surgical time and reduces overall radiation exposure for surgeons and staff. It also minimizes blood loss and muscle damage for patients, potentially yielding faster recoveries. St. Francis Hospital was the first hospital on Long Island to use the device.
