Some Great Options--Keloid Scar Removal on Earlobe: lasers, surgery
There are a few options: this can be surgically excised then treated with radiation (one dose) or 5fu/steroid injections. Or alternatively, lasers can be used such as pulsed dye and fraxel which can often give improvement without surgery. See an expert. Best, Dr. Emer.

Avoid radiation treatment. I would suggest a conservative Hidef approach with Plato's scar Serum, Kenalog IIT, and scar modulation.
