A metopic ridge is an abnormal shape of the skull. The ridge can be seenÃ‚Â on the forehead.
A metopic ridge occurs when the two halves of the frontal bones of the skull join together too soon.
The metopic suture normally begins to close in the second year of life. It is usually completely closed during the third year. However, it remains unclosed throughout life in 10% of the population.
Congenital craniosynostosis (particularly trigonocephaly) is a common cause of metopic ridge.
Call your health care provider if you notice a ridge along your infant's forehead or a ridge forming on the skull.
The health care provider will perform a physical exam and ask questions about the child's medical history.
