Summary

Burn scars can sometimes heal in a way that causes them to become thick, raised, and stiff. These scars may itch, feel uncomfortable, limit movement, and affect how the skin looks. Because of this, many burn survivors look for treatments that can help improve both the appearance and the symptoms of their scars.

One treatment that has shown promise is fractional CO₂ laser therapy. This laser creates tiny openings in the scar tissue that help soften the scar and stimulate the skin to remodel itself. These openings can also help medications applied to the skin reach deeper into the scar where they may work better.

A steroid medication called triamcinolone (TAC) is commonly used to treat these scars. Another medication, called 5-fluorouracil (5-FU), has been shown in prior studies to work well when combined with steroids, but it is usually given by injection, which can be painful and sometimes causes side effects.

In this study, we will look at whether delivering these medications through the laser openings can improve scars more effectively. Each participant's scar will be divided into two halves. One side will receive both medications, and the other side will receive the steroid alone. By comparing the two sides of the same scar, we hope to better understand whether adding 5-FU provides additional benefit.

Interventions

DEVICE

Fractional Ablative CO₂ Laser

Fractional ablative CO₂ laser treatment will be applied to assigned hypertrophic burn scar segments to create microthermal treatment zones and facilitate laser-assisted delivery of topical/intralesional study medication.

DRUG

Triamcinolone Acetonide

Triamcinolone acetonide will be administered to assigned hypertrophic burn scar segments following fractional ablative CO₂ laser treatment as part of laser-assisted corticosteroid delivery.

DRUG

Fluorouracil (5-FU)

Fluorouracil will be administered in combination with triamcinolone acetonide to assigned hypertrophic burn scar segments following fractional ablative CO₂ laser treatment to evaluate whether adjunctive 5-fluorouracil improves scar outcomes compared with triamcinolone acetonide alone.
