Abstract
Laser therapy has become a valuable treatment option for hypertrophic burn scars. Improvements in scar symptoms have been achieved using the ablative fractional carbon dioxide laser as well as the pulsed dye laser. However, research regarding the use of laser therapy among pediatric patients remains limited. Thus, the aim of this study was to investigate the effectiveness of using laser therapy to improve hypertrophic burn scars in a pediatric population using a comprehensive scar assessment protocol.
A pragmatic, single-center, prospective observational study was conducted at a tertiary pediatric hospital. Twenty participants with hypertrophic burn scars were included. Laser procedures were administered at approximately two month intervals and scars were evaluated at five time-points over one year using the Vancouver Scar Scale, the Patient and Observer Scar Assessment Scale, conventional ultrasound, ultrasound elastography, and a multi-probe skin analysis device.
Seventy-one laser procedures were performed with most participants receiving treatment with both the ablative fractional carbon dioxide laser and the pulsed dye laser at the same session (83%). From baseline to study completion, significant improvements in all scar measures were observed (p < 0.05). In particular, improvements in overall scarring and in specific scar properties including thickness, stiffness, and colour were found (p < 0.05).
To our knowledge, this is the most comprehensive study to date to evaluate the effect of laser treatment on hypertrophic burn scars in a pediatric population. Our findings suggest that laser therapy is a beneficial treatment for burn-injured children as evidenced by the improvements in subjective and objective scar assessment measures.
