The metopic suture is supposed to close between three to nine months of age.

The metopic ridge can be corrected with a (simple) burring.

The metopic suture is situated in the medial line of the forehead.

Trigonocephaly is a result from the premature closure of the metopic suture.

Hereditary relations in metopic synostosis have been found of which 5,5% were well defined syndromic.

Only one article gives valuable and reliable information regarding the incidence of metopic synsostosis in the Netherlands.

Seemingly surgery does not influence the high incidence of neurodevelopment problems in patients with metopic synostosis.

Reoperations are usually performed on more severe cases (including syndromic metopic synostosis).

The simple suturectomy is presently insufficient to adjust the complicated growth restrictions caused by metopic synostosis.

Aesthetic outcome of metopic synostosis surgery is persistently good with reoperation hazards below 20%.

The anterior fontanelle is where the metopic, saggital and coronal sutures meet.

In trigonocephaly the metopic suture is prematurely fused.

"Such a remarkable thickness of bone, and yet the metopic suture has not united," said Mr Cotton.

The metopic synostosis comes third with 5 to 15% and the lambdoid synostosis is only seen in 0 to 5% of nonsyndromic cases.

Unlike closure of the sagittal or the metopic suture, right and left are not the same in unilateral coronal synostosis.

It is also called metopic suture, although this term may also refer specifically to a persistent frontal suture (further detailed in section below).

In some individuals the suture can persist (totally or partly) into adulthood, and in these cases it is referred to as a persistent metopic suture).

A facial feature of metopic synostosis is hypotelorism; in the frontal view, it can be seen that the width between the eyes is smaller than usual.

Examination of the skull suggested a premature closure of the metopic suture, which has been suggested on the basis of his physiognomy.

Limited growth of the frontal lobes leads to an absence of stimuli for cranial growth, therefore causing premature fusion of the metopic suture.

The infant's skull consists of the metopic suture, coronal sutures, sagittal suture, and lambdoid sutures.

In 1981 Anderson advised that craniofacial operations for synostosis should be as extensive as necessary after a study of 107 cases of metopic and coronal synostosis.

His anatomy papers include Patten, C. J. Cranium of a chimpanzee, showing metopic suture; also fontanelle and sutural bone-plates.

The main elements of metopic suture closure are a low volume of the anterior cranial fossa, the metopic ridging and hypotelorism.

An increase in growth at the metopic and the sagittal suture accounts for the parallel plane and will result in bulging at the temporal fossa and an increase in width of the skull.
