The recurrence rate varies from hospital to hospital and from surgeon to surgeon, but generally speaking, the recurrence rate is less than 5%. In general, the recurrence rate is less than 5%. Experienced surgeons can reduce the recurrence rate to less than 1%. The causes of recurrence after foraminoplasty are very complex and are related to the selection of the case, the location and severity of the herniated disc, and the degree of thoroughness of the herniated disc removal during the surgery. In addition, it is also related to the patient’s age, occupation, lifestyle, weight, and co-morbidities. If the surgery is complete and the patient pays attention to maintenance after the surgery, the possibility of recurrence is very small. The surgical effect can be maintained for a long time. Individual patients have relapsed in about three days after surgery at an outside hospital. It is very rare for a patient to require reoperation after laminectomy.
