What is craniectomy?

A craniectomy is defined as the removal of part of the cranium, which is the bony structure surrounding the brain, to alleviate pressure and allow for brain swelling. This surgical procedure is often performed in cases where there is significant intracranial pressure due to trauma, strokes, or other conditions that cause the brain to expand. By removing a portion of the skull, space is created for the brain to swell without being compressed, potentially preventing further damage.

Understanding the context and significance of craniectomy is essential, particularly in neurosurgery. It is often a critical procedure performed in emergency situations where the brain may be under threat from increased pressure which could lead to brain damage or death if not addressed. The distinction between a craniectomy and other related procedures is crucial in medical practice, as it helps providers understand the appropriate interventions for various conditions.
