AbstractBackground Ablative CO2 fractional lasers have recently been introduced for burn scar treatment because of pronounced clinical outcomes with fewer treatment sessions than nonablative fractional laser.
Objective This study was conducted to observe clinical as well as histologic changes of burn scars after treatment with CO2 fractional laser.
Materials and Methods Eleven patients (one female and 10 males, aged 3159 years) with skin phototypes III to V with burn scars received 10 sessions of fractional CO2 laser treatments (UltraPulse Encore; Lumenis, Santa Clara,
CA, USA) over an average 5-week interval. Two passes were performed using the following parameters: deep FX mode, 12.530 mJ, with a density setting of 510 %. Clinical evaluations by three blinded dermatologists were obtained at baseline and at 6 months after the nal treatment via photographs using the Vancouver scar scale (VSS). Skin biopsies were done on four patients before and after treatment.
Results All patients showed clinical improvement in their scars with signicant decrease in VSS. Histologic ndings showed the changes in the upper dermis with newly formed dermal papilla. This characteristic upper dermis change
was presented as improvement in surface smoothness and skin tension clinically. Postinammatory hyperpigmentation and itching sensation were the most common adverse effects.
Conclusion Burn scar treatment by fractional CO2 laser is effective by forming new collagen bers mainly in the upper dermis.
