Keloid and hypertrophic scars occur in all types of skin, after bites, injections and inoculations, surgery and trauma. Some grow to a very large size. Keloids of the ear sometimes develop at a piercing site, and even after being removed, they can recur. To keep this risk to a minimum, the lesions are first shrunk and softened by a course of injections, and then removed with a combination of conventional and laser surgery. Results can be excellent.
