The Sutures of the Skull

Abstract

The metopic suture is a dentate type of suture traveling from the nasion to bregma. The suture is located almost in the middle of the two frontal bones and usually closes in the first or second year of life. The presence of a complete metopic suture in the adult cranium is called 'metopism'. The frequency of metopism shows variablity among geographic populations and sexes. The frequency of metopism is reported as 7–10% in Europeans, 4–5 % in Asians, 1% in Africans, and 1% in Australians, but some recent studies show there is different upper and lower limits when the populations are evaluated individually. While the prevalence of metopism among females has been reported to be between 0.32% and 23.6 %, the prevalence among males has ben reported to range from 1.56% to 17.8%. The existence of this suture in adult skulls is due to genetic influences. Metopism has anthropological, developmental, and clinical significances.
