Triangular appearance of the frontal skull due to a premature fusion of the metopic suture with associated orbital hypotelorism.
Case Discussion
Trigonocephaly accounts for around 5% of all craniosynostosis.
The metopic suture is usually open at birth and normally fuses in the first 12 months of life. Premature fusion prevents transverse growth of the forehead which causes a triangular-shaped forehead that may be associated with orbital hypotelorism as in this case.
