There is a certain chance of recurrence after syringomyelia surgery. Possible reasons for recurrence are: 1. If the patient has congenital syringomyelia but manifests as testicular syringomyelia and simply makes an incision in the testicle and does surgery for syringomyelia, there is a greater chance of recurrence after surgery. Because of congenital syringomyelia, which is an unclosed sphincter, the surgical incision should be chosen in the lower abdomen, i.e., the fistula should be ligated at the root in order to prevent recurrence. If the congenital fistula is not noted and the incision is simply made in the scrotum, there is a high probability of postoperative recurrence.2. Surgery usually chooses complete removal of the sphincter, and the chances of postoperative recurrence are very small. If the previous traditional surgical sheath reversal is used, the chances of postoperative recurrence are relatively high. Because sphincterotomy is performed, removal of the excess sphincter disrupts the secretory function of the sphincter and the chance of recurrence after surgery is very low. If syringomy is performed, the sphincter is only turned and sutured, the secretory layer that secretes fluid is still present and not removed, so there is a certain chance of recurrence after surgery.
