Since most documented syringomyelia cases are associated with CLM, the treatment of this disorder is as described under Chiari treatment. In general, the treatment of syringomyelia is aimed at restoring normal CSF flow patterns by addressing the underlying causative disorder. In cases of compression, decompression is warranted either by cranioplasty in the case of CLM, laminectomy in the case of herniated disc disease, tumor removal in cases of neoplasia, and cyst drainage in the case of intracranial or spinal cysts. Syrinx shrinkage is as gradual as its formation and in some cases can take as long as years. Most patients will experience some decrease in syrinx volume as early as 6 months after surgery.
