Gamma Knife is a bloodless and painless surgery primarily used to treat functional abnormalities and small tumors of the brain. small secondary brain tumors, pituitary adenomas, haemangiomas, Gilomas or acoustic neuroma. You go for this surgery where the lesion is inaccessible or in a functionally critical area of the brain.
It is a stereotactic radiotherapy which makes use of a three-dimensional coordinate system to locate small targets inside the body and to perform radiosurgery on them.
Gamma Knife has advanced diagnostic imaging and three-dimensional treatment planning software, delivers 192 precisely focused beams of gamma radiation to small targets inside the brain. Radiation is only delivered at a single, finely focused point where all 192 beams converge to treat the diseased tissue, while nearby healthy tissue is spared. The radiation alters the DNA and the cells no longer reproduce making the tumor inert, therefore rare chances of tumur coming back.
This treatment can be used in conjunction with other treatments like chemotherapy, radiation and neuroradiology. Unlike Chemotherapy, patients undergoing Gamma Knife will not experience any side effects like hairfall, risk of hemorrhage or infection. Their recovery time is minimal and return rapidly to pre-treatment activities.
The patient need not be administered local anesthesia during the procedure. Single procedure takes no more than 10 -70 minutes. You are awake throughout the treatment and you can be out of the hospital the same day.
