- Brain surgery is a medical procedure where a doctor operates on a person's brain to treat a condition or injury. During the surgery, the patient is put to sleep with anesthesia so that they don't feel anything. The surgeon then makes a cut in the scalp and removes a small piece of bone to access the brain. They use special tools to remove or repair any abnormal tissue or structures in the brain. After the surgery, the patient may need to stay in the hospital for a few days to recover before going home.
