I have not, but I know people who have, and unless you go to a plastic surgeon it is still going to look bad because your cartilage is already damaged. They put you under a local anesthesia and they scrape the crystals out of your ear, it makes the ear less puffy, but if the cartilage is damaged and it usually is, then the ear is still going to look weird. A good plastic surgeon, from what I understand, can make your ear look normal but it is expensive and your insurance will not cover it because it is considered cosmetic.
