[Mental evolution of 108 cases with craniosynostosis (author's transl)].

A study of mental development of 108 patients with craniosynostosis is performed. A serious mental retardation was evident in the majority of patients with "clover leaf" and in those with acrocephalosyndactily types Appert and Chotzen, and also when they had trigonocephaly. Oxicephaly, Crouzon's disease, plagiocephaly and Carpenter's and Pfeiffer's diseases show usually a moderate and/or middle retardation. Scaphocephaly has a mental evolution with a normal I.Q., but probability for presenting perinatal hipoxia because the size and aspect of the head is high.
