Answer:
False
Explanation:
Craniectomy and craniotomy are two distinct surgical procedures in neurosurgery:
- **Craniectomy**: Involves the surgical removal of a portion of the skull bone to allow the brain to swell without being compressed. This procedure is often done in cases of severe traumatic brain injury, stroke, or brain swelling where there is a need to relieve pressure on the brain. The bone flap removed during a craniectomy may or may not be replaced, depending on the patient's condition and the reason for the surgery.
- **Craniotomy**: Involves creating a surgical opening in the skull to access the brain for various procedures such as tumor removal, aneurysm clipping, or treatment of brain trauma. In a craniotomy, the bone flap is removed, the brain surgery is performed, and then the bone flap is usually replaced and secured back in place.
While both procedures involve accessing the brain by opening the skull, the key difference lies in the handling of the bone flap during the surgery and the specific purpose of each procedure.
