Passive premature synostosis results from the rapid shunting of hydrocephalus and is occasionally associated with microcephaly. Denver II Developmental Screening Test (p < 0.001) and gross motor subtest (p < 0.001) results showed statistically significant retardation in the case group compared with the control group.
