Meningocele repair is surgery to repair birth defects of the spine and spinal membranes. . For both meningoceles and myelomeningoceles, surgery consists of putting the spinal cord or nerve roots in their normal place and protecting them by closing the overlying meninges and skin.

A myelomeningocele should be closed within 24 hours of birth to prevent infection. A shunt is usually required to drain excess fluid. If the baby has fluid build-up in the brain, a shunt is usually put in when the myelomeningocele is repaired. Otherwise, most neurosurgeons wait about 3 days to place a shunt.

If hydrocephalus is present at birth and already causing problems, then the myelomeningocele repair and shunt are done at the same time.

After surgery, antibiotics are usually given to prevent infection.
