Sutura frontalis

Sutura Frontalis is a cranial suture located in the human skull. It is also known as the metopic suture or the frontal suture. The sutura frontalis is a fibrous joint that separates the two halves of the frontal bone of the skull in infants and children.

Anatomy

The sutura frontalis runs from the nasion, the point between the eyes where the frontal and nasal bones meet, to the bregma, the point on the skull where the coronal suture intersects with the sagittal suture. This suture is usually present at birth and typically fuses between the second and third years of life.

Clinical Significance

In some cases, the sutura frontalis may persist into adulthood, a condition known as metopism. Metopism is generally considered a normal anatomical variant, but it can be associated with certain medical conditions, such as craniosynostosis, a condition in which the sutures in a baby's skull fuse too early.
