Another issue with usage of intra-lesional steroids is the size, length and thickness of the needle used to inject the keloid lesions. Some physicians falsely believe that a large and thick needle should be used to inject large keloid lesions. This belief comes from the fact that injecting some old and dense keloid lesions is a rather difficult task. In treating keloid lesions, the smaller and thinner the needle is, the less damage it causes to the keloid tissue. Dr. Tirgan only uses the smallest and thinnest needles, those that are used to inject insulin under the skin. With this method, Dr. Tirgan is able to inject any keloid.
For severe cases, the keloid can surgically excised and given x-ray treatments to the site immediately afterwards, usually the on the same day. This works in about 85% of the most severe cases. Electron beam radiation can be used, which will not go deep enough to affect internal organs. Orthovoltage radiation is more penetrating and slightly more effective. There have not been any reports of this causing any form of cancer in many years of use, but it is very expensive. Silicone pads and creams are sold over the counter for use on keloids. These do benefit hypertrophic scars but will not cure a true keloid. However, they can reduce pain, swelling and itching from a keloid. They usually take 3 months or more to work.
