A comparative study of efficacy of fractional carbondioxide laser and microneedling fractonal radiofrequency in the treatment of acne scars

Background: Severe acne scars results in permanent scarring and facial disfigurement causing physical psychosocial distress. Management of poses a therapeutic challenge for the dermatologists. Ablative lasers do produce significant improvement but associated with post inflammatory hyperpigmentation, prolonged recovery time scarring. Recently development fractional carbon dioxide laser microneedling radiofrequency has proven to be quite effective treatment scars. However, till date they have not been compared side by especially Indian population. Hence, we intend conduct present comparative study. Objectives: To compare efficacy Materials Methods: A total 30 patients (18-40 years) having atrophic scars, attending out-patient department at Department Of Dermatology, Venereology Leprosy, Adichunchanagiri Hospital Research Centre, B.G. Nagara were alternately allocated into group-A (fractional CO2 group) group-B (MnRF group). Patients both groups received four sequential treatments an interval 4 weeks between each session. Clinical assessment was done based on Goodman & baron grading system end 1 month after last session, comparison preoperative post-operative photographs. In addition, asked provide their opinion using patient satisfaction Visual Analogue Score (VAS). Results: At one session (4 sessions) Baron’s qualitative assessment, 3(20%) showed reduction 3 grades group B 2 (13.3%) A. 10(66.6%) 9(60%) which found statistically no
