Background:
In recent years, fractional ablative lasers at low density have proven to be the centerpiece in a multimodality approach to treating hypertrophic burn scars.
Objective:
To determine the safety and efficacy of fractional ablative erbium-doped yttrium aluminium garnet (Er:YAG) laser in the treatment of hypertrophic burn scars.
Methods:
Eleven patients received 3 fractional ablative Er:YAG laser to hypertrophic burn scars at 400 to 800 μm, density 11%, no coagulation, and single pass at 4-week intervals.
Results:
Overall, average improvement was noted to be 2.27 of 3 as determined by blinded observers. A significant improvement was noted in all measured parameters including dyschromia, atrophy hypertrophy, vascularity, and texture.
Conclusion:
This is a pilot study showing the safety and efficacy of fractional ablative Er:YAG laser treatment is a safe and effective treatment modality in the treatment of hypertrophic scars.
