ABSTRACT
Objective:
To observe the efficacy and adverse reactions of fractional radiofrequency (FRF) in the treatment of facial acne scars.Methods:
Fifty-seven patients with facial acne depressed scars were enrolled with the nature of Dreno scars as the diagnostic criteria. They were treated with lattice radiofrequency. The treatment heads were arranged in a matrix with a treatment area of 1.2 cm ×1.2 cm, an energy density of 80-100 mJ/pin, and an interval of five-seven once a week. And they were followed up and evaluated for the clinical efficacy and adverse reactions 6 months after the last treatment. Scoring was carried out according to the ECCA weight scores, and the efficacy judged according to complete improvement, significant improvement, moderate improvement, and mild improvement.Results:
After 3 times of fractional radiofrequency treatment of 57 patients, the effective rate was 44 cases, accounting for 77.2%; the ECCA weight scores before and after treatment were 65.9±25.0 and 47.7±20.2, respectively; the difference was statistically significant ( t=13.92, P<0.001); At the same time of improvement, 32 cases of patients' complexion, fineness of pores, and skin elasticity had been improved to varying degrees, and patient satisfaction was high. Adverse reactions were mainly mild burning sensation, erythema and edema, and some patients had pale yellow exudate, etc, which could be relieved in 5-7 days.Conclusions:
Fractional radiofrequency treatment of facial acne scars is safe and effective, with short recovery period, few adverse reactions and high patient satisfaction.
