Examination of the skull suggested a premature closure of the metopic suture, which has been suggested on the basis of his physiognomy.

Metopic synostosis represents 5 % to 15 % of cases, and lambdoid synostosis is seen in 0 % to 5 % of nonsyndromic cases.

Examples include : trigonocephaly ( fusion of the metopic suture ), brachycephaly ( fusion of the coronal suture and lambdoid suture bilaterally ), dolichocephaly ( fusion of the sagittal suture ), plagiocephaly ( fusion of coronal and lambdoidal sutures unilaterally ), and oxycephaly or turricephaly ( fusion of coronal and lambdoid sutures ).

Examples include : trigonocephaly ( fusion of the metopic suture ), brachycephaly ( fusion of the coronal suture ), dolichocephaly ( fusion of the sagittal suture ), plagiocephaly ( unilateral premature closure of lambdoid and coronal sutures ), oxycephaly ( fusion of coronal and lambdoidal sutures ), Kleeblattschaedel ( premature closure of all sutures ).
