Fractional Photothermolysis for the Treatment of Burn Scars

Phase 1

• Conditions: Scar

• Registration Number: NCT01005992
• Lead Sponsor: Clinica las Condes, Chile

Brief Summary

The aim of our study is to determine the effect of fractional photothermolysis laser in the treatment of burn scars.

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.
