Burr holes are used in cranial injuries primarily for which purpose?

Explanation:
The key idea is rapid decompression to relieve rising intracranial pressure. In acute head injuries, pressure inside the skull can spike quickly and threaten brain tissue and blood flow. Making small openings in the skull—burr holes—allows blood, clotted material, and CSF to escape, providing quick relief of pressure. This buys time and helps prevent brain herniation while more definitive treatment (like a craniotomy or other procedures) is arranged. While burr holes can be used to drain some subdural hematomas, their primary use in an emergency is to achieve rapid decompression, not as a definitive treatment for chronic conditions. They aren’t about replacement after craniotomy, and they are indeed used in emergencies.
