myelotomy

Limited midline myelotomy for the treatment of pelvic visceral cancer pain (Gildenberg and Hirshberg, 1984).

As a result, "'punctate midline myelotomy'" was introduced around the world as a new surgical procedure for the treatment of visceral pain residual to cancer and refractory to conventional treatment.

Further studies showed that this model, when combined with a lumbar spinal cord myelotomy leads to the hindbrain herniation characteristic of the Chiari II malformation and that in utero surgery restores normal hindbrain anatomy by stopping the leak of cerebrospinal fluid through the myelomeningocele lesion.
