[Craniosynostosis, a pediatric perspective].

Craniosynostosis is defined as the premature fusion of one or more skull sutures, characterized by an abnormal shape of the head. It is a rare condition but should be recognized and timely referred to Neurosurgery in order to prevent complications. The objective of this review is to describe the most frequent clinical and genetic characteristics of this pathology, its classification according to the shape of the skull, and the most characteristic signs to achieve timely recognition. A search for scientific articles in Pubmed, Scielo, and EMBASE databases was performed using the terms craniosynostosis, plagiocephaly, scaphocephaly, and brachycephaly. We selected articles in Spanish and English that described the characteristics of the pathology and about its management, choosing systematic reviews or recommendations from scientific societies when available. Craniosynostosis may occur in isola tion or associated with other deformities. Its classification depends on the affected suture(s), leading to the characteristic shape of the skull and the presence of other malformations. This condition is usually diagnosed and referred late, which is associated with complications such as intracranial hy pertension and impaired brain development. Early surgery has less comorbidity and better esthetic results. In conclusion, the abnormal shape of the skull must raise the suspicion of craniosynostosis, even if it occurs in isolation. Surgical management before one year of life is associated with a better prognosis.
