Cross Technique With 100 % Tca Versus Microneedling With Platelet Rich Plasma in Treatment of Atrophic Acne Scars –A Comparative Study

Introduction: Acne scarring is a common complication of acne which can have physical, social and psychological impact and signicantly reduced quality of life of the patients. Cross technique with 100 % trichloroacetic acid and microneedling are established treatment for scars, although the efcacy of microneedling with platelet-rich plasma has not been explored much. To compare the efcacy and safety of 100 % Aim And Objectives: trichloroacetic acid and microneedling with platelet rich plasma in treatment of atrophic acne scars. 16 patients with Method: atrophic scars were enrolled, divided into two groups. Group A underwent cross technique with 100 % Trichloroacetic acid and group B was treated with microneedling with topical application of platelet rich plasma. four sessions were given at an interval of 2 weeks. Goodman's Qualitative scale was used for the nal evaluation of results. Sixteen patien Result: ts were enrolled with a mean age of 24.00 ± 6.00 years. Both groups showed statistically highly signicant improvement in the degree of acne scars severity after treatment (p<.001). Subjectively 60% patient showed good response,20% showed very good response and 20% showed excellent response. Both modalities represent equally effective and safe treatment options f Conclusion: or atrophic acne scars with no statistically signicant difference in the degree of improvement (p =0.81). moreover, it was concluded that cross technique with 100% trichloroacetic acid is effective in ice pick and shallow rolling scars, while microneedling with platelet rich plasma is efcacious in deep rolling and box scars. However, considering side effects, microneedling with platelet rich plasma showed minimal post inammatory hyperpigmentation therefore it is a better modality for treatment of acne scars.
