Gamma Knife Radiosurgery

  • What is Gamma Knife Radiosurgery?

    Often used on brain tumours, gamma knife radiosurgery is a form of radiation therapy that accurately focuses hundreds of individual laser beams at a tumour. It is often used as an alternative therapy to chemotherapy, surgery or other forms of radiation oncology.

    Usually, only sedation or local anaesthesia is needed for gamma knife radiosurgery. Patients do not have to go under the knife, thus reducing their risk of infection and bleeding. Treatment typically lasts about 15 minutes to over an hour, depending on the patient’s condition.

    Patients usually do not feel any pain, but may feel slight discomfort from the local anaesthesia. A headframe, which is fitted onto patients to prevent any head movement, may also cause slight discomfort.

  • Gamma knife surgery can be used to treat both benign and malignant brain tumours, especially tumours that begin from a primary tumour elsewhere in the body that have metastasised (spread) to the brain. It can also be used to treat arteriovenous malformations (AVMs), an abnormal collection of blood vessels, and nerve disorders like trigeminal neuralgia, among others.

    The effects of the gamma knife radiosurgery will not be immediate but will be seen over a period of time. Radiation treatments are designed to stop the growth of tumours or lesions, which means the progress will only be seen over a period of weeks or months. Your doctor will stay in contact with you during this period and you may have to have follow-up MRI, CT or angiography examinations to track your progress.

    Our specialists will be able to assess if gamma knife surgery is a suitable treatment for your condition. Make an appointment for a gamma knife surgery consultation here.
