A Intermountain Healthcare answered. A craniotomy is a surgery to cut an opening in the skull and expose the brain. Here's what to expect: A neurosurgeon makes an incision through the skin and cuts out a small section of your skull, called a bone flap. The bone flap is removed to expose the brain underneath. The hematoma (a buildup of blood underneath the outer layer of the brain, from small veins that have been torn) is drained or removed. The bone flap is secured back in place, and the incision is closed back up with either sutures (stitches) or staples.
By definition, a hematoma is a collection of blood outside of a blood vessel. It occurs because the wall of a blood vessel wall, artery, vein or capillary, has been damaged and blood has leaked into tissues where it does not belong.he hematoma may be tiny, with just a dot of blood or it can be large and cause significant swelling. The blood vessels in the body are under constant repair. Minor injuries occur routinely and the body is usually able to repair the damaged vessel wall by activating the blood clotting cascade and forming fibrin patches.
