Frontal suture

Frontal Suture

The Frontal Suture is a fibrous joint that separates the two halves of the frontal bone of the skull in infants and children. Typically, it completely fuses between the ages of two and eight, leaving a faint remnant in adulthood.

Anatomy

The frontal bone is a bone in the human skull. The bone consists of two portions. These are the vertically oriented squamous part, and the horizontally oriented orbital part. The two portions are separated by the Frontal Suture.

Development

During infancy and early childhood, the Frontal Suture allows for the rapid expansion of the brain and the skull. This suture is not present in all individuals and can fuse at various times after birth. If the suture closes too early, a condition called craniosynostosis can occur, leading to abnormalities in the shape of the skull.

Clinical Significance

In some cases, the Frontal Suture fails to fuse and remains open in the adult skull. This condition is known as a metopic suture. It is usually harmless but can be associated with certain syndromes and conditions.
