ROA, Ignacio; MORAGA, José Ignacio  and  CANTIN, Mario. Metopism: Morphologic Basis Clinical Implications and Case Report. Int. J. Morphol. [online]. 2011, vol.29, n.3, pp.992-999. ISSN 0717-9502.

During fetal life and infancy, flat bones of the cranial vault are separated by dense connective tissue membranes, fibrous joints called sutures, which are aimed early on in life to promote brain development. Eventually these sutures close over the years to form a synostosis between the bones of the skull. One of these is the frontal suture, which joins the two frontal bones in the embryonic period and the newborn. This suture may persist over time, generating the condition known as metopism. Alteration showing different presentations and incidents depending on the ethnic group studied. The purpose of this paper is to show the features found in this condition, frequency, description, varieties, etc. This analysis was performed on different databases and the description of a case. It raises the importance that clinicians approaching the area at the time of surgery consider possible confusion at the radiographic level which can lead to subsequent complications. Therefore, real knowledge of the morphological bases of this condition is important for correct diagnosis and surgical procedure if warranted.
