When a child has metopic synostosis: The metopic suture — the joint that runs from the baby’s fontanel (the “soft spot” at the top of the head) down the forehead to the top of her nose — closes too early. The baby develops a noticeable ridge extending along the center of her forehead.
Are ridges on baby’s head normal?
In an infant only a few minutes old, the pressure from delivery compresses the head. This makes the bony plates overlap at the sutures and creates a small ridge. This is normal in newborns. In the next few days, the head expands and the overlapping disappears.
Are skull ridges normal?
The skull is not perfectly round or smooth, so it is normal to feel slight bumps and ridges. However, a dent in the head, especially if it is new, requires a trip to the doctor to determine the cause.
What is a cranial ridge?
The cranial ridges, also referred to as exo-cranial ridges or cranial plates are bony plates on the surface of the forehead on many humanoid species. Some species, such as Humans, Vulcans, and the ancient humanoids do not possess visible cranial ridges.
When does babies head stop pulsing?

At what age is craniosynostosis diagnosed?
But as your baby grows, a misshapen head could be a sign of something else. The earlier you can get a diagnosis—ideally, before the age of 6 months—the more effective treatment can be. Craniosynostosis is a condition in which the sutures in a child’s skull close too early, causing problems with head growth.
Why is my skull bumpy?
The most common cause of skin lumps is trauma or injury. This type of lump is sometimes called a goose egg. It occurs when you hit your head or another part of your body. Your skin will begin to swell, causing a lump that may also be bruised.
