What is a Cranial Decompression?

Cranial decompression is a surgical procedure performed to relieve pressure inside the skull, often caused by a traumatic brain injury, brain swelling, or other conditions that lead to increased intracranial pressure. During the procedure, the surgeon removes a section of the skull (craniectomy) to allow the brain to expand and reduce pressure on the brain tissue. This procedure is crucial for preventing further brain damage and can help improve recovery outcomes. In some cases, the removed portion of the skull may be replaced once the pressure is relieved.

Surgery aims to treat the following conditions:

1. Traumatic brain injury (TBI): TBI occurs when a blow or jolt to the head causes brain injury, which can result in swelling, bleeding, and increased pressure within the skull. Cranial decompression helps to alleviate the dangerous effects of this pressure.
2. Brain swelling (cerebral oedema): Swelling of the brain often results from injury, infection, or stroke, and can cause a significant increase in intracranial pressure. Decompression helps to reduce this pressure and prevent permanent brain damage.
3. Intracranial haemorrhage: Bleeding in or around the brain can lead to a buildup of blood, which increases pressure on the brain. Cranial decompression removes the pressure, allowing the brain to function more effectively.
4. Stroke: In certain cases of ischemic or haemorrhagic stroke, cranial decompression may be necessary to reduce the pressure and preserve brain function.
