Posterior cranial vault distraction is a treatment for intracranial hypertension in certain cases of craniosynostosis and faciocraniosynostosis. It allows the harmonization of the skull back and prevents turricephaly. This study presents the surgical technique.

Posterior cranial vault distraction osteogenesis consists of a circular osteotomy of the skull back. Four distractors are placed on the cranial flap without detachment of the dura mater. The distraction is carried out over nearly 1 month with an objective of 20mm. The technique's effectiveness is judged on the correction of the skull back shape and the disappearance of clinical and radiological signs of intracranial hypertension.

Posterior cranial vault distraction osteogenesis enables a large increase in cranial volume and a correction of the dysmorphic skull back. This easy surgery and the low rate of complications make this technique a main surgical approach in the management of faciocraniosynostosis.
