Premature closure of the metopic suture is a relatively rare form of craniosynostosis, accounting for less than 15% of all cases [2, 3, 6, 8, 18, 32, 37, 39].Isolated metopic suture synostosis occurs in 1 in 2,500 to 1 in 70,000 live births [1, 7].Syndromic forms are believed to be even rarer, and include Opitz C syndrome, Say–Meyer syndrome, and Frydman syndrome [7, 34, 36].

Trigonocephaly is a relatively rare deformity of the skull characterized by triangular prominence of the bones of the forehead and orbital hypotelorism. Developmental and acquired abnormalities of the skull and scalp can occur throughout childhood. It is characterized by early fusion of the metopic suture, which presents with a restriction of frontal growing, dysmorphic orbital roofs, and skulls with a triangular shape [9] . Hypotelorism refers to an abnormal decrease in distance between any two organs although some authors use the term synonymously with orbital hypotelorism meaning an abnormal decrease in the distance between the two eyes (the eyes appear too close together).
