Analysis and Late Treatment of Plagiocephaly: Unilateral Coronal Synostosis

Abstract

Assessment of plagiocephaly has always been hindered by the lack of normal structures which can be used as a reference. The primary malformation is cranial, that is, premature synostosis of the coronal suture unilaterally. This is known to all, but still unproven are associated synostosis of the cranial base. Secondary deformities, considered as compensatory, exist on the contralateral side. These cranial anomalies affect the development of all the facial bones. In the final analysis, everything is abnormal: malformed or deformed. Plagiocephaly is the most complete presentation of craniofacial asymmetry (Fig. 1).
