What is a disadvantage of the mature skull?

The skull is rarely affected by disease. Uncommon ones like osteitis deformans and acromegaly cause the bones to increase in size. Like other bones, the skull may be fractured by blows, falls, or other accidents, but skull fracture can be far more dangerous because of its proximity to the brain. If the brain swells, it will get compressed.
