Craniectomy versus Craniotomy for Traumatic Brain Injury Decompression

Quick fact

In a decompressive craniectomy, up to 12 cm of skull is removed and not immediately replaced, giving the swollen brain room to expand. Craniotomy replaces the bone immediately, but provides less room for swelling.

Why this is interesting

When a devastating head injury makes the brain swell, surgeons face a choice: leave the skull open or put it back. That single decision can tip the balance between who survives and who lives with severe disability.
