The surgical procedure for pediatric syringomyelia is a sheath removal and sheath flipping procedure performed under general anesthesia, which is the most routine and effective surgical procedure. After satisfactory anesthesia, a 2cm incision is made in the scrotum, layer by layer to the testicular sphincter layer, the sphincter is extruded outside the scrotum, the excess sphincter is cut out, the two sides of the sphincter are flipped and sutured, the spermatic cord and testis are fixed to the meatus, and the operation is over. After the surgery, attention should be paid to whether there is bleeding from the scrotum and whether there is complication of acute testicular and epididymitis, and the recovery can be normal five days after the surgery.
