Microneedling for Burn Hypertrophic Scars

A 5% lidocaine anesthetic cream will be applied to the scar to be treated and will be wrapped with an occlusive dressing (saran wrap) for 30 minutes prior to the procedure. The same scar will be subjected to the ACS-Pen treatment at a depth of 1.5 mm or less depending on the results of the thickness measurement performed prior to treatment. Within 5 minutes after the microneedling treatment, a thin layer of triamcinolone acetonide and 2% xylocaine (1:3 ratio) suspension will be spread over the scar. The physician will then gently massage the product into the microneedling columns. The same amount will be used for each subsequent treatment. The patient will also be given a small amount of hydrocortisone 2.5% (low potency corticosteroid) to be applied to the treated site at 12 hours and 24 hours post-treatment.
