Brief Summary

Approximately 33 to 91% of severe burn victims will develop hypertrophic scars. Hypertrophic scars are defined as erythematous (red), raised and rigid scars that can cause pain and itching, among other things. They cause psychological distress and affect the quality of life of burn victims. Microneedling is a technique that uses an electrical device to create hundreds of microchannels that penetrate the skin layers. This study is interested in determining the effectiveness of microneedling in improving the pliability, thickness and erythema of hypertrophic scars. Each scar will receive up to 5 ACS-pen treatments followed by the application of cortisone (triamcinolone acetonide). Knowing that microneedling increases the absorption of products applied to the skin by about 80%, it is logical to think that creating these channels to the dermis and applying cortisone afterwards would have a beneficial effect on the hypertrophic scars of these patients.

Outcome Measures

Primary Outcomes (3)

  • Skin Erythema Changes

    Erythema index measure by Mexameter, values from 0 to 999. The erythema values are individual for each person and depend strongly on the ethnic group. The measurements are generally used to determine changes before and after a treatment.

    Baseline, before treatments #3, #4 and #5, post 6 weeks and 12 weeks

  • Cutometer Skin Elasticity Changes

    Skin elasticity measures (r0- Cutometer), mm

    Baseline, before treatments #3, #4 and #5, post 6 weeks and 12 weeks

  • Skin Thickness Changes

    Ultrasound skin measures, mm

    Baseline, before treatments #3, #4 and #5, post 6 weeks and 12 weeks

Secondary Outcomes (1)

  • Patient reported effectiveness of intervention

    Baseline, 12 weeks post intervention

Interventions

MicroneedlingPROCEDURE

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.
