An intralesional steroid injection involves a corticosteroid such as triamcinolone acetonide injected directly into a lesion on or immediately below the skin. Intralesional administration of corticosteroids treats a keloid or hypertrophic scar directly. In contrast to topical steroids, intralesional steroids:
Bypass the barrier of a thickened stratum corneum
Reduce the chance of epidermal atrophy (surface skin thinning)
Deliver higher concentrations to the site of the pathology.
The procedure of this treatment involves injecting intralesional steroid solution into the abnormal skin and aims to improve the appearance of the keloid scar as well as relieving symptoms such as itching or pain.
We perform intralesional injection of a steroid. No special preparation is required, and a local anaesthetic is not needed. Depending on the size of the area to be treated, you may need several injections. This type of treatment can work alongside laser treatment for keloids.
