Recurrence of traffic syringomyelia needs to be observed first, and surgical treatment needs to be considered if the condition does not resolve. Traffic syringomyelia is a phenomenon in which the syringomyelia protrudes from the sheath and does not close, causing the syringomyelia sac to communicate with the abdominal cavity, resulting in a buildup of fluid in the syringomyelia sac. If a child under 1 year of age has a recurrence of traffic syringomyelia after treatment, it can be observed. This is because there is a possibility of spontaneous healing. If the effusion gradually decreases over time, then surgical treatment is not necessary. If the recurrence of syringomyelia is followed by a gradual increase in fluid over time, then timely surgical treatment is needed. If traffic syringomyelia occurs after the age of 2 years and the syringomyelia continues to increase, surgery is recommended. If traffic syringomyelia recurs after surgery, then another surgery is needed in a timely manner. It is important to seek medical attention after a recurrence of traffic syringomyelia, and it is up to the doctor to decide how to treat it and whether to treat it with observation.
