trigonocephaly
Sign in to saveAlso known as Trigonocephaly type 2, Craniosynostosis, Metopic, Trigonocephaly 2, Trigono 2, Trigono2, trigonocephalus, trigonocephalia
Trigonocephaly is a congenital condition due to premature fusion of the metopic suture (), leading to a triangular forehead. The premature merging of the two frontal bones leads to transverse growth restriction and parallel growth expansion. It may occur as one component of a syndrome together with other abnormalities, or in isolated form. The term is .

==Cause== thumb|Fused suture in trigonocephaly thumbnail| Trigonocephaly as a kind of craniosynostosis Trigonocephaly can either occur in a syndrome or isolated, all by itself. Trigonocephaly is associated with the following syndromes: Bohring-Opitz syndrome, Muenke syndrome, Jacobsen syndrome, Baller–Gerold syndrome and Say–Meyer syndrome. The etiology of trigonocephaly is mostly unknown although there are three main theories. Trigonocephaly is probably a multifactorial congenital condition, but due to limited proof of these theories this cannot safely be concluded.
