Since its first use in 1968, more than 850,000 patients have been treated with Gamma Knife Radiosurgery. Approximately 70,000 people each year have this procedure. And the reason why is the safety and superb outcomes.
More than 2,500 studies have been published in peer-reviewed scientific medical journals documenting the effectiveness of Gamma Knife Radiosurgery. These studies provide evidence that Gamma Knife treatment is often the most effective treatment with the least side effects for many complex brain conditions, including brain metastases, arteriovenous malformations, trigeminal neuralgia, meningiomas, acoustic neuromas, gliomas and pituitary tumors.

Gamma knife surgery for trigeminal neuralgia stops pain in 85-90 percent of patients, most within 10 days. If you experiencing the debilitating pain of trigeminal neuralgia, you should consider Gamma Knife surgery as a treatment option. The most relevant research studies include:

Various studies have found that tumor control rates for acoustic neuromas with Gamma Knife surgery are 92 to 97 percent after five years. The majority of acoustic tumors up to 3 centimeters qualify for Gamma Knife treatment, so talk with your physician about whether you’re a candidate for this treatment option. The most relevant research studies include:

Gamma Knife surgery successfully treats 93 percent of meningioma cases and is particularly useful for meningiomas that involve vital structures in the brain. The majority of meningiomas 3.5 centimeters and smaller can be treated with Gamma Knife, so you should consult with a Gamma Knife neurosurgeon about whether you’re a candidate for this treatment option.

Gamma Knife surgery is one of the most effective treatments for metastatic brain tumors, providing between 84 and 97 percent local tumor control. Single or multiple tumors that are 3 to 4 centimeters or smaller can be treated with Gamma Knife. Although LINAC radiosurgery is often presented as a comparable substitute for Gamma Knife and have been in existence for about the same length of time, thousands of research studies have shown the outstanding outcomes achieved with Gamma Knife. If you or a loved one has metastatic brain cancer, you should seek a second opinion from a neurosurgeon trained in Gamma Knife Radiosurgery. The most relevant research studies include:
