Surgical procedure for children with syringomyelia: I. Most children with syringomyelia are traffic syringomyelia, so the surgical incision is mostly chosen in the inguinal region, and the length of the incision is about 4 cm. Second, the incision starts from 2 cm above the midpoint of the inguinal region and ends above the pubic tuberosity, and the depth of the incision needs to reach the muscle layer. Third, after entering the muscular layer, the tendon membrane of the external oblique abdominal muscle is incised and the sheath of the lateral spermatic cord is found after separating the muscle. After opening the sphincter and confirming the traffic with the abdominal cavity, the sphincter is ligated. Fourth, if the effusion sheath cavity of the scrotum is large, the secretory layer in the sheath cavity will be destroyed after aspiration of the effusion to avoid postoperative recurrence. V. Checking that there is no active bleeding in the surgical field and that there is no secretion or oozing of blood from the sheath cavity, the incision can be closed and the skin sutured in sequence.
