Abstract:
Objective:To investigate the efficacy of pixel 2 940 nm erbium laser combined with vitamin B12 in the treatment of acne sunken scar.Methods:From July 2017 to June 2019, 96 patients with acne sunken scar were treated in the Department of Burn and Plastic Surgery of the Second People＇s Hospital of Jiaozuo City, Henan Province. They were randomly divided into two groups with 48 cases in each group. The control group was treated with routine therapy and the observation group was treated with pixel 2 940 nm erbium laser combined with vitamin B12. The therapeutic effects, acne scar weight score (ECCA), skin condition and adverse reactions were compared between the two groups.Results:The total effective rate of the control group was 77.08% (37/48), which was lower than that of the observation group 91.67% (44/48) ( P<0.05); The incidence of adverse reactions, pore and amethyst in ECCA score of the control group were (18.14±9.33), 18.75% (9/48), (32.25±8.41) and (18.24±5.12), which were higher than those of the observation group (26.45±12.60), 4.17% (2/48), (28.24±7.52) and (15.63±4.34) ( P<0.05), respectively. Conclusions:Pixel 2 940 nm erbium laser combined with vitamin B12 is effective in the treatment of acne sunken scar, with less adverse reactions and high safety. It is worthy of clinical application.
