Gamma Knife surgery may be used to treat:

• brain tumors, including malignant and benign tumors, specifically ones that cannot be reached with traditional brain surgery or following surgery
• tremors, including essential tremor or tremor caused by Parkinson’s disease
• acoustic neuroma, also known as vestibular schwannomas, or tumors that develop around the nerves of the inner ear
• trigeminal neuralgia, a condition that affects the nerves in the face
• vascular malformations, or tangles of blood vessels in the brain

People with multiple brain tumors or lesions may not be good candidates for Gamma Knife surgery because of the high radiation exposure risk.

Depending on your health condition, Gamma Knife surgery may be one of many treatment options, or it may be considered the best option because of the risks associated with other treatments.
