| Craniectomy is the surgical removal of a portion of skull (cranium), leaving an opening in the skull that may be left open or covered with synthetic material. This procedure is often used to remove tumors in the rear of the brain (cerebellum) and to relieve brain swelling. A craniectomy also allows surgical treatment of diseases that affect the cranial nerves supplying sensation and movement to the structures of the head and neck. The procedure is classified as an emergency if pressure within the skull (intracranial pressure), usually from bleeding within the brain or its coverings, has increased to a dangerous level.
A craniectomy is performed in a major operating room under general anesthesia. |
