I have not had time to read Jen Brea's story in full . However, I think some of her starting facts may be wrong. Looseness of craniocervical ligaments does not cause the skull to drop as far as I know. The skull is bone and sits on the bone of the first cervical vertebra (atlas). Since there is no gap, loosening of ligaments is not going to make the bones any nearer. I doubt that craniocervical fusion raises the skull up in any way. It just fixes it to the atlas and axis. During the years that I referred patients for surgery like this nobody ever suggested that the skull was raised up.
