Trigonocephaly is a type of cephalic disorder. This is the premature fusion of the metopic suture (part of the frontal suture which joins the two halves of the frontal bone of the skull) in which a V-shaped abnormality occurs at the front of the skull. It is characterized by the triangular prominence of the forehead and closely set eyes. Genetic testing may be offered to determine the cause and recurrence risk.


Surgery can greatly reduce the visual effects of trigonocephaly. It can also help address comorbid elevated intracranial pressure.[1]


It is believed that the first surgery to correct the disorder was successfully completed in early 1962 in San Diego, California, on a six-month-old girl.[2]
