How can i fix a?keloid scar as a result of ear piercing?

Several options...: First, you need to make sure it is, in fact, a keloid. If it is, there are several options. We have had very good results with surgically removing the keloid and then performing a series of steroid injections directly into the operative wound starting about three weeks postoperatively. Other options include pressure treatment and low dose radiation. See a plastic or facial plastic surgeon.

Injection: Keloids from ear piercing can be treated with injections, and pressure earrings. If inadequate the keloid can be excised, and injected. There is a 50% recurrence rate. In addition to excision radiation can be used to cut the recurrence rate.
