Gamma Knife Radiosurgery
Gamma Knife radiosurgery is a sophisticated radiation tool known worldwide for its precise treatment to targeted areas of the brain. Patients with benign tumours and functional conditions of the brain are treated with focused single day high dose radiotherapy treatment. The most common conditions treated include acoustic neuromas, meningiomas, trigeminal neuralgia, arteriovenous malformations, and pituitary adenomas.
In a single treatment session, 201 beams of gamma radiation can focus with a precision of less than 1 mm. The exposure is brief and only the tissue being treated receives the radiation dose, while the surrounding tissue remains unharmed.
Since Gamma Knife radiosurgery is performed without incisions or general anesthesia, many of the usual risks associated with conventional neurosurgery, such as neurological deficit, infection and bleeding, are reduced.
Patients are discharged from the Gamma Knife Centre on the day of treatment and are usually able to return to their normal activities within 72 hours.
