During surgery for a brain tumor, the surgeon will cut away a small part of the bone and either cut away a flap of skin or insert a needle to remove some tissue for biopsy. The patient may be asleep under general anesthesia during surgery, or, if brain function must be monitored, the patient may be awake, with the incision area numbed.
The surgeon may use imaging such as computed tomography (CT), magnetic resonance imaging (MRI), or ultrasound to see and pinpoint the tumor and remove as much as the tissue as possible without affecting normal function.
After surgery, typically the bone is put back in place with metal screws and plates or wires. The patient may spend several days in the hospital, then heal at home for several weeks.
