[Application of fractional laser resurfacing in the treatment of superficial scar].
OBJECTIVE
To study the therapeutic effect, safety and risk of fractional resurfacing with ablative laser in the treatment of superficial scar.


METHODS
88 cases of superficial scar, including 66 cases of acne scar, 12 cases of burn scar and 10 cases of other scar, were treated. All the patients were treated with Pixel (Er:YAG 2940 nm, > or = 3 times), or Encore (Ultrapulse CO2 10600 nm, > or = 2 times), or a combination of Pixel and Encore( > or = 3 times).


RESULTS
The therapeutic effect of treatment was graded as medium when the scar was improved > 25%, as good when the scar was improved > 50%. The effective result was achieved in 80% of the patients. Good effect was achieved in 50% of the patients. There were 244 treatments of Pixel and 86 treatments of Encore. Persistent hyperpigmentation was happened in one case with Encore treatment, which relieved four months later. No other complication was happened.


CONCLUSIONS
The fractional resurfacing with ablative laser is an effective method for superficial scar, especially acne scar. It is mini-invasive with low risk. The key mechanism is the ability of enhancing the tissue remodeling induced by heat effect of laser.
