Significant brain trauma often causes swelling, [ edema,] of the brain. The skull is a rigid closed container and pressure can rapidly increase and threaten survival. Crainiectomy produces a large opening in the skull to allow extra space for the brain to swell until the edema resolves. This is frequently an emergency procedure.
Evacuation of intracranial hematoma
Brain injury is often associated by bleeding in or next to the brain producing a clot, [ hematoma.] The clot can rapidly produce damaging pressure against the brain which can be treated by surgical removal. This is frequently an emergency procedure.
After a craniectomy when the brain swelling resolves and the patient recovers, the skull can be repaired for protection of the brain and cosmetic reasons. The skull opening can be repaired with the patient's preserved bone or a variety of synthetic substitute materials.
