Roughly, from the studies, it seems that if you do not take steroids you have about a 15 in 20 chance of full recovery of the nerve function. But, if you take a steroid medicine, you have about a 17 in 20 chance of full recovery. So, taking a course of steroids does not guarantee full recovery of the nerve function. However, it increases the chance of full recovery compared to no treatment. You should start the course of steroids as soon as possible after the onset of symptoms; ideally, within 72 hours of symptoms starting. They may not have much effect if they are taken after this.
