There are several types of Brain tumor surgery and specialists use various tools and techniques to help them remove the brain tumor.
A craniotomy is the most prevalent type of surgery for a brain tumor. The surgeon cuts out an area of bone from the skull. This provides an opening so that the surgeon can work on the brain itself.
Physicians ask for different scans before the surgery to help the surgeon identify where precisely the tumor is. Scans are also sometimes carried out during surgery. Some surgeons use an image-guided method where the scans are uploaded into a computer to give the precise location of your tumor. On removing the brain tumor, the surgeon sets the area of bone back. They fasten the flap with permanent tiny metal brackets and then stitch the scalp in place over it. In most of the problems, the hair hides the surgery scars.
The surgeon can recommend awake craniotomy surgery when you have a tumor close to the brain that manages an important function. For example, if a person has a tumor that is close to the part which controls the speech, movement, or feeling.
There are various ways of carrying out an awake craniotomy. Some people are conscious during a part of the surgery while other people are awake during the whole surgery procedure. The surgeon decides what is going to happen in such a situation. Finally, this is followed by another general anesthesia for the last part of the operation
During the surgery, general anesthesia is given at the start of the operation if the patient is going to be awake for part of it. The anesthesia is further reduced so that you can wake up for the main part of the surgery. For either method, the surgeon applies local anesthesia to numb any sections that feel pain like the skin and muscle. The brain may not feel the pain.
Throughout awake craniotomy surgery, the surgeon might ask you to do tasks that are mainly done to check the functioning of different parts of the brain. You might be asked to speak, move part of your body, or check what you can feel. This is called function mapping. The surgeon does this so that he can get assured that these functions are not injured.
