Unilateral syringomyelia does not usually require bilateral treatment, and the treatment may vary depending on the age and condition of the patient, such as testicular sheath removal. If one side of the syringomyelia has fluid and the other side has no symptoms, preventive surgery is usually not performed. In general, adults with syringomyelia who have no symptoms or a small amount of fluid can be left untreated and followed up regularly. If the amount of effusion is large or the symptoms are obvious, testicular syringomyelia can be removed and reversed. In case of traffic syringomyelia, the syringomyelia can be ligated in high position. It is important to note that congenital syringomyelia in infants may not be treated urgently with surgery, as it is often self-absorbed and subsides. If symptoms persist after the age of 1 year, surgery may be considered. Patients are advised to seek prompt medical attention if they feel unwell.
