Fractional Photothermolysis for the Treatment of Burn Scars
Fractional Photothermolysis for the Treatment of Burn Scars
The aim of our study is to determine the effect of fractional photothermolysis laser in the treatment of burn scars.

One of the main problems in the management of burned patients is the treatment of post-burn scarring. Frequently this scars cover large areas, tend to retract, present pigmentary changes and are disfiguring, producing significant life quality impairment.

Unfortunately, there are very few therapeutic options for treating these scars, which can be secondary to reconstructive surgery or after spontaneous healing. In the last decades most reports in scar treatment have included, pressure garments, chemical peeling, dermabrasion, ablative and non-ablative laser therapy and surgery with varying degrees of success. There is only one report treating burn scars with fractional laser, with good results.

The aim of our study is to determine the effect of of a second-generation erbium-doped 1,550-nm fractional photothermolysis laser (Fraxel SR laser, Reliant Technologies Inc.) in the treatment of burn scars.

Interventional
Phase 1
Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Scar
  • Procedure: Fractional laser treatment
    A complete treatment will consist in four laser sessions with a second-generation erbium-doped 1,550-nm fractional photothermolysis laser (Fraxel SR laser, Reliant Technologies Inc at 1-month intervals. Treatment will be delivered with a 15-mm tip and concomitant air-cooling system (Zimmer MedizinSystems, Irvine, CA). Fluence and treatment level will be registered on every session and will be adjusted according to patient tolerance.
  • Procedure: Standard scar management
    The standard treated scar arm consists of a similar lesion in an equivalent location in the same patient or the half of a lesion that is suitable to be divided (size at least 4% body surface area). This arm will be managed only with standard burn treatment modalities.
  • Experimental: Laser treated scar
    The standard treated scar arm consists of a similar lesion in an equivalent location in the same patient or the half of a lesion that is suitable to be divided (size at least 4% body surface area). This arm will be managed only with standard burn treatment modalities.
    Intervention: Procedure: Fractional laser treatment
  • Active Comparator: Standard scar management
    The standard scar management arm consists of a similar lesion in an equivalent location in the same patient or the half of a lesion that is suitable to be divided (size at least 4% body surface area). This arm will be managed only with standard burn treatment modalities.
    Intervention: Procedure: Standard scar management
