What is the purpose of a burr hole in a craniotomy?
A burr hole is a small, surgically-created opening in the skull in order to access the brain tissue. During a craniotomy, a burr hole may be used to drain excess fluid or to allow a surgeon access to the brain in order to remove a tumor or treat a brain injury. The burr hole also serves to provide a pathway for instruments to reach the brain.
