Types of Chiari Malformation

10. Other Possible Interventions

Other interventions depend on the type and severity of the Chiari malformation. Infants with myelomeningocele may need surgery to reposition the spinal cord and close the defect. Often, a surgeon will perform this procedure while the baby is still in the womb, as this is more effective. While hydrocephalus is commonly treated with a shunt, another option is third ventriculostomy. A small hole is made in the bottom of the third ventricle that allows the flow of cerebrospinal fluid, relieving pressure.
