Treatment for Chiari 1 malformation (CIM): analysis of a pediatric surgical series

Research output: Contribution to journalArticlepeer-review


Children may present a peculiar picture of CIM, as syncopes and acute paraparesis. In a series of 99 children operated for CIM at FINCB there were no major surgical morbidity nor mortality. The preoperative symptoms improved more in this pediatric series than in the adult cases treated at the same institution in the same period; a reason could be the shorter duration of symptoms and another the children plasticity. An untreated nonsyndromic craniosynostosis was present in 10 cases. In our hands, the results of the limited extradural decompression were poor. In some CIM associated with psychiatric symptoms an unexpected improvement was observed after tonsilar resection. The associated Syringomyelia reduced in more than 80% of children and disappeared in a significant number. The rare associated tethered cord (5%) needed a double treatment, detethering by itself being insufficient to treat also tonsillar descent. The clinical symptoms are often more serious in children than in the adults, but the results of surgery, especially on the syrinx, are better.
