Usually laminectomy is less invasive and recovery is quicker, with full recovery taking about a month or so. Because minimally invasive surgery is less traumatic, but after all, it is surgical trauma and may cause spinal nerve edema. It takes about one month for the spinal nerve edema to subside and for the nerves to return to normal function. In the later stage, you need to actively change the medication and disinfection to prevent the infection of the incision. For spinal nerve edema, local numbness symptoms need to apply dehydration and hormone treatment, such as mannitol, dexamethasone, and need to apply nutritive drugs to promote nerve recovery.
