We have experienced 15 cases of cranium bif idum in the past 3 years, including 4 cases with frontal cranum bifidum. The sites were frontoethmoidal in 2 cases and interfrontal in 2 cases. They have been followed from 1 to 3 years of age and all are living. As complications, 1 case had intracranial lipoma and 2 cases had myelomeningocele. Restoration of frontal encephalomeningocele and honey defect was performed by an intracranial procedure in 2 cases. Severe hypertelorism in 1 case was corrected by bilateral transfer of the whole orbit at one year after birth. There are few reports of frontal cranium bif idum in Japan. Three cases with craniolacunia were all complicated by congenital hydrocephalus and ventriculoperitoneal shunt was carried out. The above 4 cases were analysed clinically and are here reported.
