Definition Return to top
A metopic ridge is a ridge of bone or elevated connection between bones (ridged suture) visible on the forehead extending from the front of the fontanel forward onto the forehead (between the two halves of the frontal bone).Considerations Return to top
A metopic ridge is similar to other ridged sutures. It is caused when the two halves of the frontal bones of the skull fuse together prematurely.
The metopic suture normally begins to close in the second year of life, and is usually completely closed during the third year -- although it does persist unclosed throughout life in 10% of the population.
There is no treatment or surgery required for a metopic ridge.
