Abstract
Autologous fat transfer (AFT) has been proposed as a possible treatment for scar tissue and its associated symptoms. Its effectiveness's evidence is yet unidentified though. The aim of this meta-analysis is to evaluate the currently available evidence on the efficacy and safety of autologous fat transfer in treating post-burn and post-traumatic scars using a validated scar measurement tool. This study performed a systematic literature review in November 2023 using the following electronic databases: MEDLINE, SCOPUS, Directory of Open Access Journals (DOAJ), PUBMED, and Google Scholar. The following key terms were included: (Fat grafting OR Autologous fat transfer) AND (body scars OR body burns OR body wounds) AND (Efficacy OR Safety OR satisfaction). We evaluated articles according to predefined quality criteria. The following data wereincluded during the extraction period: patient demographics, indications for AFT, the number of AFT sessions, follow-up periods, and changes in the Patient and Observer Scar Assessment Scale (POSAS) scores, which contain both the patient and observer components. This study included 1326 patients and 23 published articles. A total of 14 prospective studies, 7 retrospective studies, and 2 Randomized clinical trials studies were evaluated. These 23 articles came from diverse global locations; the earliest was published in 1992, and the most recently published in 2022. Our findings demonstrated significant enhancements in scar characteristics from both patient and observer perspectives. Overall, AFT holds promise as a valuable treatment option for scar-related conditions as it enhances scar quality ,contributing to improved patient outcomes and satisfaction. This journal requires that authors assign a level of evidence to each article.
