[Remodeling the cranial vault in anterior craniosynostoses. Our therapeutic experience of trigonocephaly and plagiocephaly].

The authors propose two simple techniques to improve the adaptation of the frontal vault after remodeling the orbito-naso-frontal flap in anterior craniostenosis. In trigonocephaly: the metopic suturectomy is enlarged by lateral translation of the two half frontal bones, then to fall the place the coronal suture is used. The temporal plates are moved forward and turned to fill the failure of fronto-temporal junction due to valgisation of orbito-naso-frontal band. In plagiocephaly: the frontal flattened flap is cut with oblique radial osteotomies starting at bregma so called "Daisy petal". The first internal petal is sacrificed. The others are rotated axially in a medial direction. Internal table corticotomies must be performed at two levels to recurve the flattening and to obtain a curve in the coronal plane. In this two techniques the pericranium and dura-mater must be carefully teated to obtain a better adaptation of the new bone shape and to permit the spontaneous reossification.
