Observation of the clinical therapeutic effect of ultra pulsed carbon dioxide lattice laser on acne scars
Objective To analyze the clinical effect of ultra pulsed carbon dioxide lattice laser on acne scars. Methods 106 patients with acne scars were divided into a control group and an observation group according to a 1∶1 ratio using a random number table method,with 53 cases in each group. The control group received conventional treatment,while the observation group received ultra pulsed carbon dioxide lattice laser treatment based on the control group. The clinical efficacy,occurrence of adverse reactions,and scar severity were compared between the two groups. Results The total clinical effective rate of the observation group was 94.34％,which was higher than 81.13％ of the control group,and the difference was statistically significant (P<0.05). The incidence rate of adverse reactions in the observation group was 9.43％,and the difference was not statistically significant compared with 7.55％ in the control group (P>0.05). Compared with before treatment,the scores of skin thickness,color,softness and vascular distribution in both groups were significantly improved after treatment;in the observation group,the skin thickness score was (0.61±0.22) points,the color score was (0.61±0.21) points,the softness score was (0.71±0.12) points,and the vascular distribution score was (0.74±0.19) points,which were lower than (0.98±0.31),(0.81±0.23),(0.79±0.22),and (1.42±0.26) points in the control group;the difference was statistically significant (P<0.05). Conclusion Ultra pulsed carbon dioxide lattice laser scheme in the treatment of acne scars can improve the scar severity,ensure the effectiveness and safety of treatment,and is worth learning from and implementing.
