Jun 4, 2023 · The metopic suture (also known as the frontal, interfrontal, or median frontal suture) is a vertical fibrous joint that divides the two halves of the frontal bone and is present in a newborn. Persistent metopic sutures can be misdiagnosed as vertical skull fractures, therefore it is important to be aware of this anatomical variant.
The frontal suture is a fibrous joint that divides the two halves of the frontal bone of the skull in infants and children. Typically, it completely fuses between three and nine months of age, with the two halves of the frontal bone being fused together.

The metopic ridge is a palpable (able to be touched or felt), bony ridge running down the middle of a child’s forehead. The metopic suture line runs from the top of the head down to the center of the forehead. An infant’s skull is made up of five bony plates connected by four sutures.These sutures remain flexible to allow the baby's head to fit thr...
A metopic ridge without other symptoms is not serious and does not require treatment. However, when other symptoms occur, a metopic ridge may be a sign of craniosynostosis. Craniosynostosis affects the flexible joints (sutures) in an infant’s head. These sutures, which usually remain open and flexible until a child is two years old, fuse prematurel...
When sutures fuse too early, the head becomes misshapen and does not grow properly. Metopic craniosynostosis usually causes a child to have a triangular-shaped head, in which the forehead is very narrow, and the back of the head is the long side of the triangle. In addition to a metopic ridge, the classic signs of metopic craniosynostosis include: ...
Contact your healthcare provider if you notice a ridge along your infant's forehead or a ridge forming on the skull, with or without additional symptoms such as a triangular head shape and close-set eyes.
Metopic ridge can usually be diagnosed with a physical exam. Your doctor will closely examine your child’s forehead and feel along the ridge. To confirm the diagnosis, your pediatrician may recommend a computed tomography (CT) scan of the head or a skull X-ray.
Craniosynostosis is typically treated with surgery to reshape the skull into a more circular form and to allow sufficient room for the brain to grow naturally. Mild cases of craniosynostosis may not require surgery.A special medical helmet may sometimes be used to shape the skull into a more regular shape. No treatment is needed for a normal metopi...
A metopic ridge is a prominent ridge running down your child's forehead. It is where suture lines meet between the two bony plates. A congenital defect called craniosynostosis, in which one or more sutures fuse prematurely, can cause a metopic ridge. However, a metopic ridge can be benign if it presents without other symptoms, such as a narrow fore...
A metopic ridge is a normal thickening of the bone on the forehead caused by the fusion of the metopic suture. It may also be a sign of craniosynostosis, a rare condition that affects skull growth and brain development. Learn how to recognize and treat a metopic ridge and craniosynostosis.
Jun 3, 2021 · Metopism is the presence of a complete metopic suture in the adult cranium, which is a normal variant. The chapter reviews the epidemiology, etiology, anatomy, and clinical significance of metopism and its relation to craniosynostosis.

Learn about metopic synostosis, a condition where the metopic suture in the skull fuses too early, causing a triangular forehead and eyes that appear too close together. Find out the symptoms, causes, diagnosis, and treatment options at Boston Children's Hospital.
The major sutures of the skull include the following: Metopic suture. This extends from the top of the head down the middle of the forehead, toward the nose. The 2 frontal bone plates meet at the metopic suture. Coronal suture. This extends from ear to ear. Each frontal bone plate meets with a parietal bone plate at the coronal suture. Sagittal ...
Aug 8, 2012 · The metopic suture separates the two frontal bones at birth and is the first skull suture to close physiologically, starting as early as at 3 months and generally being completely fused at the age of 8 months [, ].
