Syringomyelia (/sáµ»ËrÉªÅÉ¡ÉmaÉªËiËliÉ, -É¡oÊ-/) is a generic term referring to a disorder in which a cyst or cavity forms within the spinal cord. This cyst, called a syrinx, can expand and elongate over time, destroying the spinal cord. The damage may result in pain, paralysis, weakness, and stiffness in the back, shoulders, and extremities. Syringomyelia may also cause a loss of the ability to feel extremes of hot or cold, especially in the hands.
Surgery types include: Treating Chiari malformation. If syringomyelia is caused by Chiari malformation, your doctor may recommend surgery that involves enlarging the opening at the base of your skull (suboccipital craniectomy) and expanding the covering of your brain (dura mater).
