Gamma Knife Surgery: Powerful and Precise
Gamma KnifeSurgery is recognized worldwide as the preferred treatment for brain tumors, arteriovenous malformations and brain dysfunctions such as trigeminal neuralgia. The Gamma Knife offers a non-invasive alternative for many patients for whom traditional brain surgery is not an option. Gamma Knife surgery removes the physical trauma and the majority of risks associated with conventional surgery. This effective single session treatment may require an overnight hospital stay, but is often done in an
outpatient surgical setting with periodic follow-up.
Gamma Knife surgery represents a major advance in brain surgery, and in the last three decades has changed the landscape within the field of neurosurgery. Its development has enhanced neurosurgical treatments offered to patients with brain tumors and vascular malformations by providing a safe, accurate and reliable treatment option. Gamma Knife enables patients to undergo a non-invasive form of brain surgery without surgical risks, a long hospital stay or subsequent rehabilitation.
Gamma Knife surgery is unique in that no surgical incision is made to expose the inside of the brain, thereby reducing the risk of surgical complications and eliminating the side effects and dangers of general anesthesia. The "blades" of the Gamma Knife are the beams of gamma radiation programmed to target the lesion at the point where they intersect. In a single treatment session, 201 beams of gamma radiation focus precisely on the lesion. Over time, most lesions slowly decrease in size and dissolve. The exposure is brief and only the tissue being treated receives a significant radiation dose, while the surrounding tissue remains unharmed. With the Gamma Knife, a surgical incision is not required; the attendant risks of open neurosurgical procedures (hemorrhage, infection, cerebrospinal fluid leakage, etc.) are therefore avoided.
Conditions for which the Gamma Knife is considered most effective are:
Intracranial tumors such as acoustic neuromas, pituitary adenomas, pinealomas, craniopharyngiomas, meningiomas, chordomas, chondrosarcomas, metastases and  Astrocytomas .

Vascular malformations including arteriovenous malformations, cavernous malformations. Functional disorders such as Trigeminal
neuralgia , Intractable pain , Parkinson’s disease, Essential tremors , Epilepsy and Obsessive-Compulsive disorder.

Advantages of  Gamma Knife:

Gamma Knife is a neurosurgical tool designed exclusively for the treatment of brain disorders.
The lesion being treated receives a high dose of radiation with minimum risk to nearby tissue and structures.
The cost of a Gamma Knife procedure is  less than traditional neurosurgery.
Patients experience little discomfort.
The absence of an incision eliminates the risk of hemorrhage and infection.
Hospitalization is short, typically an overnight stay or an outpatient surgical procedure. Patients can immediately resume their previous activities.
Gamma Knife technology allows treatment of inoperable lesions. The procedure offers hope to patients who were formerly considered untreatable or at very high risk during open skull surgery.
