This procedure creates an opening through the skull for brain tumor removal. The surgery usually takes from two to five hours. Electrodes may be placed on the patient's face so the surgeon can monitor the health of the sensitive facial and other cranial nerves and help prevent nerve damage during the procedure.
As the procedure begins, the surgeon creates a long, arched incision in the scalp. This tissue is folded back to expose the skull. The surgeon then creates one or more small holes in the skull and cuts the skull between these holes to free a section. This skull flap is removed and stored. The surgeon then carefully opens the thin membrane the covers the brain.
The surgeon may insert soft, flexible retractors to hold healthy brain tissue aside to expose the tumor and protect surrounding tissue. The surgeon carefully removes the tumor from the brain with a scalpel, suction device, electrocautery device or other instrument.
When the removal is complete, the surgeon closes the membrane and replaces the skull flap, anchoring it to the skull with plates and screws.
