Which is a common early neurosurgical intervention for traumatic brain injury?

• A. Lumbar puncture.
• B. Cranial burr hole repair.
• C. Cranioplasty.
• D. Decompressive craniectomy.

Answer: (D)

Relieving elevated intracranial pressure is the key idea here. In severe TBI, the brain can swell so much that pressure inside the skull stays high despite medical treatments. Decompressive craniectomy directly addresses this by removing a portion of the skull, giving the swollen brain space to expand outward rather than being compressed inward. This maneuver lowers intracranial pressure quickly and reduces the risk of brain herniation, which can be life-saving in the early phase after injury. Because of that, it’s the common early neurosurgical step when ICP remains high or edema is diffuse and refractory to medical management. Other options don’t fit as well: a lumbar puncture is dangerous with high ICP and can precipitate herniation; a small burr-hole procedure can relieve some pressure from focal bleeds but doesn’t provide the broad relief needed for diffuse swelling; cranioplasty is a reconstruction after the initial injury and not an acute ICP-lowering intervention.
