Steroid injections

Steroid injections


Corticosteroid injections can be used for the prevention and treatment of raised scars, like keloids and hypertrophic scars and are normally the first-line option.

Corticosteroids suppress inflammation and mitosis while increasing vasoconstriction in the scar resulting in flattening of the scar and reduction of pain or itchiness of the scar.

The specific corticosteroid for keloid and hypertrophic scar treatment is Triamcinolone acetonide suspension (Kenalog) 10 to 40 mg per mL is injected intralesionally, which, although painful, will eventually flatten 50 to 100 percent of keloids, with a 9 to 50 percent recurrence rate. Newer keloids are more responsive to therapy than older, established lesions.

Procedure


  1. You will have a detailed medical consultation and examination by our experienced doctor prior to the treatment.
  2. Topical or local anaesthetic may be applied/ injected to help reduce discomfort of the injection prior to the steroid injection. Alternatively, Lidocaine (Xylocaine) anaesthetic may be combined with the corticosteroid to lessen discomfort.
  3. Steroids will be injected into the scar tissue.
  4. The treated areas will be covered with plasters which should be kept on at least one hour.
  5. Review appointment will be scheduled for one month after the treatment.

How many injections will I need?

The exact number of steroid injection sessions needed is difficult to determine.

It is recommended you should have an injection once a month until the keloid is completely flattened. Then you can observe if the keloid grows back. If it starts to grow back, you may need to have the steroid injection to maintain the flattening effect. Depending on the severity of the keloid, most of the keloid that has been treated shouldn’t recur. However, if it does to start to grow back, you may need further injections every few months or years.

You may expect some discomfort at the treated areas for the first one to two days. Mild swelling of the scars can be expected next day. Then the scar will gradually flat down over the next four weeks that you will see the maximum result of the injection.

Risks and complications


Common risks and complications are just temporary for steroid injection including local side effect like discolouration, telangiectasia ( visible of small capillary blood vessels ), thinning of the skin and depression/ dip on the treated area and around the area. It is very rare that it becomes a permanent effect. These temporary complications usually disappear a few months after you stop the injection.

Other therapies


Other therapies with limited studies include intralesional verapamil, fluorouracil, bleomycin, and interferon alfa-2b injections. Although all of these have results comparable or sometimes superior to corticosteroid injection and silicone sheeting, the optimal keloid therapy remains undefined. Combinations of therapies have proved superior to individual approaches.
