The metopic suture should have been closed well before the man reached his teens and should have been completely closed by the age of 6 or 8. The metopic suture occurs in the frontal bone of the skull. In an adult skull this suture is known as the coronal suture.

Pneumoencephalographic and skull X-rays are‚ how and why this was done‚ how long it takes to recover from this‚ and what the side effects are of having this done.

That fluid protects the brain from damage‚ but makes it very difficult to X-ray‚ since images taken through fluid are cloudy. Pneumoenceph alography involved drilling holes into the skulls of research subjects‚ draining
