Insights
Fractional laser therapy, with or without pulse dye laser, improved hypertrophic burn scars in children. Treatment showed significant benefits for scar pigmentation and vascularity across most body regions, aiding pre-treatment counseling.
Area of Science:
- Dermatology
- Pediatric Surgery
- Regenerative Medicine
Background:
- Hypertrophic burn scars in pediatric patients often require intervention.
- Laser therapy is a recognized treatment for burn scars, but its efficacy varies by body region and prior treatments.
- Limited data exists on the effectiveness of laser treatment for pediatric burn scars based on specific anatomical locations and previous therapies.
Purpose of the Study:
- To evaluate the effectiveness of fractional CO2 laser therapy, with or without pulse dye laser, on pediatric hypertrophic burn scars.
- To analyze treatment outcomes stratified by body region and prior burn wound management.
- To provide data for improved pre-treatment counseling for patients and families.
Main Methods:
- Retrospective study of 99 pediatric burn patients treated between 2018-2022.
- Utilized fractional CO2 laser, with or without pulse dye laser, for scar treatment.
- Assessed scar improvement using the modified Vancouver Scar Scale (mVSS) scores, analyzing changes by body region and scar characteristics.
Main Results:
- A total of 332 laser sessions were administered.
- Significant improvements were observed in mVSS scores for anterior trunk, arms, and legs.
- Key scar components, including pigmentation and vascularity, showed significant reductions (p < 0.001), alongside overall mVSS score improvement (p < 0.001).
Conclusions:
- Fractional laser treatment, alone or combined with pulse dye laser, is effective in improving pediatric hypertrophic burn scars.
- Treatment benefits are evident across multiple body regions, particularly in reducing pigmentation and vascularity.
- These findings support the use of laser therapy and aid in setting patient expectations regarding outcomes.
Abstract:
Paediatric patients with hypertrophic burn scars benefit from laser treatment, but this treatment's effectiveness on burn wounds stratified by specific body region and prior burn wound therapy has not been fully evaluated. We performed a single center retrospective study of pediatric burn patients, treated with fractional CO2, with or without pulse dye, laser between 2018-2022. We identified 99 patients treated with 332 laser sessions. Median age at the time of burn injury was 4.0 years (IQR 1.7, 10.0) and 7.1 years (IQR 3.6, 12.2) at the time of first laser treatment. In the acute setting, 55.2 % were treated with dermal substrate followed by autografting, 29.6 % were treated with dermal substrate alone, and 9.1 % underwent autografting alone. Most body regions showed improvement in modified Vancouver Scar Scale (mVSS) score with laser treatment. mVSS scores improved significantly with treatment to the anterior trunk (-1.18, p = 0.01), arms (-1.14, p = 0.003), and legs (-1.17, p = 0.015). Averaging all body regions, the mVSS components of pigmentation (-0.34, p < 0.001) and vascularity (-0.47, p < 0.001), as well as total score (-0.81, p < 0.001) improved significantly. Knowing the variable effectiveness of laser treatment in pediatric burn scars is useful in counseling patients and families pre-treatment.

The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...
