Amelioration of Chiari type 1 malformation and syringomyelia following posterior calvarial distraction in Crouzon's syndrome--a case report.

Multisutural craniosynostosis as seen in Crouzon's syndrome can result in raised intracranial pressure, Chiari malformation (CM) and syringomyelia. Posterior calvarial distraction (PD) is a technique for addressing cranio-cephalic disproportion, and this case report describes the reversal of both CM and syrinx in a 6-year-old child who underwent PD initially for raise intracranial pressure.
