A series of 74 cephaloceles (17 cranial meningoceles and 57 meningoencephaloceles) is reported. Infants born with large meningoencephaloceles containing recognizable cerebral tissue usually did badly despite endeavors to conserve brain function by expanding the cranial capacity (5 cases) or decompressing hydrocephalic ventricles (9 cases). Infants with cranial meningoceles almost all did well, even when there was associated hydrocephalus. The etiological diversity of cephaloceles is emphasized. Frontoethmoidal meningoencephaloceles, which occur with noteworthy frequency in South and Southeast Asia, require separate consideration in both genetic counseling and treatment; the associated facial deformities (hypertelorism and orbital dystopia) can be corrected with a one-stage craniofacial reconstruction. Antenatal diagnosis by ultrasound is now often possible and was achieved in 4 cases; we suggest that neurosurgeons should participate in such antenatal evaluations.
