Abstract

Background: Scarring and facial disfigurement caused by severe acne can cause significant physical and psychosocial distress, particularly in adolescents. In treating acne scars, dermatologists face a therapeutic challenge. Ablative lasers Erbium YAG lasers or carbon dioxide lasers are effective, but they are associated with erythema, post-inflammatory hyperpigmentation, a longer recovery time, and scarring. With the introduction of fractional carbon dioxide lasers, acne scar treatment has become much more effective. PRP contains growth factors, which helps to speed up the natural healing process. As a result, combining fractional CO2 laser with platelet rich plasma has resulted in significant improvement of acne scars with good cosmetic results and skin rejuvenation. Through this study, we intend to assess the efficacy of fractional carbon dioxide laser with platelet rich plasma versus fractional carbon dioxide laser alone in the improvement of facial acne scars.
Objectives: To compare the efficacy of fractional carbon dioxide laser with and without platelet rich plasma (PRP) in treatment of facial acne scars.
Materials and Methods: A total of 30 patients (18-40 years) with facial atrophic scars who attended the out-patient department at the Department of Dermatology, Venereology, and Leprosy, Adichunchanagiri Hospital and Research Centre, B.G. Nagara were randomly assigned to groups A (fractional CO2 with PRP group) and B (fractional CO2 group). Patients in both groups received four sequential treatments, with a four-week interval between each session. A side-by-side comparison of preoperative and post-operative photographs was used to assess the clinical improvement of atrophic scars one month after the last session, using Goodman and Baron's qualitative and quantitative grading system. Furthermore, patients were asked to provide feedback on scar improvement using the patient satisfaction Visual Analogue Score (VAS).
Results: Based on Goodman and Baron’s qualitative assessment one month after the last session (4 sessions), 13.33 percent (2) of patients in group A showed reduction by three grades compared to 6.66 percent (1) patient in group B, and 60 percent (9) of patients in both groups showed scar reduction by two grades. Based on Goodman and Baron’s quantitative assessment one month after the last session (4 sessions), 20 percent showed very good reduction in group A compared to 13.3 percent in group B, and 40 percent showed good reduction in group A compared to 33.3 percent in group B. [p=0.732, not statistically significant]. Patients treated with fractional carbon dioxide laser with PRP in group A had a slightly better mean percentage reduction of post acne scars at one month after the last session (4 sessions) compared to patients treated with fractional carbon dioxide laser in group B [75.83 vs 69.34 percent; p=0.72 which was statistically not significant]. At one month after the last treatment session (4 sessions), 66.67 percent (10) of patients in Group A were very satisfied with the treatment, compared to 46.67 percent (7) of patients in Group B. After four treatment sessions, the mean Patient Satisfaction VAS Score in Group A was 2.0, compared to 1.7 in Group B [p=0.000082, which was found to be statistically significant].
Conclusion: The result of this study shows that combination of fractional CO2 laser with intradermal PRP is slightly more efficacious than fractional carbon dioxide laser monotherapy in management of facial acne scars. Patients receiving fractional carbon dioxide laser with PRP were more satisfied with the treatment outcome.
