Metopic Synostosis or Trigonocephaly is a hot topic among families and surgical teams.
The Metopic suture is the only suture that will close during infancy. Upon closure, the Metopic suture may form a palpable ridge aka “Metopic Ridge”. To date, there is still controversy as to where the clear diagnostic threshold lies.
A “classic case” of Trigonocephaly will only appear in 14-15% of cases. A “classic case” will include, narrow/triangular shaped forehead, biparietal widening( the parietal bones are the bones forming the central side and upper back part of each side of the skull), and hypotelorism (is an abnormal decrease in distance between the eyes).
Metopic Synostosis is likely to present before the infant is six months old.
