The frontal suture is a dense connective tissue structure that divides the two halves of the frontal bone of the skull in infants and children. It usually disappears by the age of six, with the two halves of the frontal bone being fused together. If it does not disappear it may be called a "metopic suture" or "sutura frontalis persistens." If the suture is not present at birth (craniosynostosis) it will cause a keel-shaped deformity of the skull called "trigonocephaly."
