[Meningoencephalocele. A report of 6 cases]

The paper deals with the study of 6 patients having this malformation. Four were nasofrontal, 1 nasoethmoidal and 1 occipital cases. The last associated to harelip and cleft palate. Two of them exhibited neurologic deficiency. All underwent surgery, 3 in two steps, through intracranial approach and section of the encephalic segment, followed by osteoplasty from iliac crest for replacement the flawed piece of cranial bone. Afterwards straight aesthetic reconstruction. As etiological causation is accepted the parents multifactorial action of nutritional imbalance, tobacconism and the effect of weed-killers--so much employed in our country--which set in motion, all of them, the output of free radicals acting upon DNA of germinative cells. In this way is breacked the H bonds, determining the congenital malformations on the offspring. Diabetes and dipsomania are rejected.
