Who is a candidate for Gamma Knife surgery?

Gamma Knife surgery - which actually isn't surgery, but a finely targeted delivery of radiation beams - was developed specifically to treat brain disorders. It has long been recognized as the only option for many patients who, for health reasons, may not be candidates for conventional open surgeries.But the procedure often is the best option for anyone considering treatment for a variety of brain disorders. Because there is no incision, the recovery time, potential for infection, and bleeding risk are all substantially reduced, making it an attractive option for many patients. In addition, Gamma Knife's precise delivery means that only the targeted area of the brain receives radiation, while surrounding health tissue remains intact.

At Rocky Mountain Gamma Knife Center, our team of specialists will carefully review your medical history and discuss treatment options with you to determine whether you are a good candidate for a Gamma Knife procedure. In general, patients who are most likely to benefit from Gamma Knife surgery are those whose conditions include:

  • Benign brain tumors, including meningiomas (non-cancerous tumors)
  • Metastatic brain tumors/brain cancer
  • Malignant primary brain tumors, including glial or glomus tumorsGamma_Knife_treatment.gif
  • Tumors deep within the brain or in a location difficult or impossible to reach with open surgery
  • Trigeminal neuralgia
  • Acoustic neuroma, also called vestibular schwannoma, a type of benign tumor on the cranial nerve that controls balance and hearing
  • Vascular malformations including arteriovenous malformations
  • Intracranial tumors such as pituitary adenomas, pinealomas, craniopharyngiomas, chordomas, chondrosarcomas
  • Lesions that have recurred after conventional surgery
