To remove a brain tumor, a neurosurgeon makes an opening in the skull. This operation is called a craniotomy. Whenever possible, the surgeon attempts to remove the entire tumor. If the tumor cannot be completely removed without damaging vital brain tissue, your doctor may remove as much of the tumor as possible.
A craniotomy is the surgical removal of part of the bone from the skull to expose the brain. Specialized tools are used to remove the section of bone called the bone flap. The bone flap is temporarily removed, then replaced after the brain surgery has been done.
In total, it typically takes about 4-8 weeks to make a full recovery from a brain surgery. The initial incisions on your head may be sore for about a week afterwards. You may have some mild headaches for a period of about 4-8 weeks as well.
It could take up to 3-5 hours if you are having a regular craniotomy. If you have an awake craniotomy, the surgery could take 5-7 hours.
