This procedure creates an opening through the skull for removal of a hematoma, or blood clot, inside the brain. The surgeon creates a long, arched incision in the scalp above the hematoma. The soft tissue is folded back to expose the skull. The surgeon drills one or more small holes into the skull and then saws between the holes to free a section of bone. This "skull flap" is removed and stored. The surgeon carefully opens the dura (the membrane that surrounds the brain), allowing access to the brain tissue.
The surgeon uses instruments to carefully move the brain tissue aside, exposing the hematoma. A suction device is used to remove the hematoma. Areas around the hematoma that continue bleeding will be cauterized.
