Study Description
Brief Summary:
The aim of our study is to determine the effect of fractional photothermolysis laser in the treatment of burn scars.

Condition or disease Intervention/treatment Phase
Scar Procedure: Fractional laser treatment Procedure: Standard scar management Phase 1

Detailed Description:

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.

Arms and Interventions

Arm Intervention/treatment
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.
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.
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.

Outcome Measures

Primary Outcome Measures :
  1. Evidence of improvement in color and texture of burn scars, using digital colorimeter and digital photography. [ Time Frame: 5 months ]
  2. Adverse effects: pain, erythema, edema, hypopigmentation, hyperpigmentation, hypertrophic scar and keloid formation [ Time Frame: 5 months ]

Secondary Outcome Measures :
  1. Change in surface area and perimeter of burn scar [ Time Frame: 5 months ]
  2. Tissue pliability, elevation and flexibility with a digital piedemeter [ Time Frame: 5 months ]
  3. Change in collagen fiber organization and blood vessel density with a reflectance laser confocal microscope. [ Time Frame: 5 months ]
