[Turned biparietal transposition. A new technic for correcting back of the skull dysmorphisms]

The authors describe a new surgical technique for the deformities of the back of the skull vault. They use a biparietal flap which is turned upside down in order to extend the back of the skull. They use this technique for the correction of craniosynostosis (posterior plagiocephaly, pachycephaly). 12 children have been operated with this technique since 24 month.
