Usually foraminotomy is less invasive and recovery is faster, with full recovery taking about a month. Although minimally invasive surgery is less invasive, it is after all a surgical trauma and may cause spinal nerve edema. It takes about one month for the spinal nerve edema to subside and for the nerve to return to normal function. It is necessary to actively change the medication and disinfection to prevent infection of the incision at the later stage. For spinal nerve edema, local numbness should be treated with dehydrating agents and hormones, such as mannitol and dexamethasone, and nerve nourishing drugs should be applied to promote nerve recovery.
