There are several types of Brain tumor surgery and
specialists use various tools and techniques to help them remove the brain
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 for an 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 which 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 situation. Finally this 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
Throughout the awake craniotomy surgery, the surgeon might
ask you to do tasks which 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.
