| Abstract | ||||
| Background: Hypertrophic Scars result of abnormal wound healing due to an inflammatory process within the wound and are mainly constituted of fibroblasts formation, neoangiogensis and substantial deposition of collagen. HS likely arise during a few months in high tension area and can persist along the margins of the original wound. While, hypertrophic scars arise after various injury mechanisms, surgeries are considered to be one of the major causes. Objective: The aim of this study was to evaluate the efficacy of low energy carbon dioxide laser therapy in management of hypertrophic surgical scars in comparison to the standardized high energy modes in regards of scar ablation and patient satisfaction. Methods: This study is a prospective and a comparative that compared traditional High energy with Low Energy fractional CO2 laser in treatment of Hypertrophic post surgical scars. This study was conducted between April 2021 and March 2022 at the Laser Unit attached to plastic surgery Department, Ain Shams University. The study included 40 patients (N=40), all of which were complaining of post Abdominoplasty hypertrophic scars and were divided blindly into 2 groups. In group I (n=20), they were treated by standard high energy fractional CO2 laser therapy. In group II (n=20), they were treated by lower energy modes than group I. Both groups were treated by Syneron/CANDELA CO2RE® laser machine and both groups were evaluated by 3 different observers using the VSS score once before starting sessions and twice on 2 separate occasions after completion of sessions. Patients in both groups evaluated themselves by POSAS score. Results of both groups were compared in regards to mean age, history of Abdominoplasty, history of massive weight loss, post-session complication, skin quality, mean POSAS and VSS scores before and after. Conclusion: In this study, we have concluded that high frequency fractional CO2 laser offers greater results in regards to scar ablation. On the other hand, the low frequency fractional CO2 laser scar ablation is likely to offer moderate results. Overall, this selection of frequencies allows the physician options to customize the appropriate care for their patients according to their patients’ needs and circumstances. | ||||
