Consensus: trigonocephaly.

Abstract

Trigonocephaly mostly occurs in isolated synostosis of the metopic suture, but 10-20% of patients are affected by complex syndromes, and in 2-5% the condition is familial. Intracranial hypertension has been observed in a minority of cases, but is never severe. Surgery is performed mainly for cosmetic reasons, following the standard principles of craniofacial surgery. Complications are rare and satisfactory cosmetic results are generally obtained. There is little likelihood for recurrent deformity.
