[Plagiocephaly. Craniofacial asymmetry with variable curling-up].

The plagiocephaly syndrome is an asymmetrical cranial deformity due to premature synostosis of a coronal hemi-suture. The predominant alteration is at the spheno-frontal suture. The classification is attempted between the isolated plagiocephaly (P) an plagiocephaly with hypertelorism, on one side, that are to be distinguished from complex asymmetrical cranio-facial deformities.
