RESUMO
BACKGROUND: 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. METHODS: 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 were included 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. RESULTS: 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. CONCLUSION: 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. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.

RESUMO
Fires in operating rooms are rare yet devastating incidents. There are guidelines for the prevention and management of surgical fires; however, these recommendations are based on expert opinion and case reports. Almost all surgical procedures have an oxidizer (oxygen, nitrous oxide), an ignition source (such as a laser or "Bovie"), and a fuel, which together make up the three elements of an operating room fire. Our review analyzes each fire component to decide on the most effective clinical approach for reducing the risk of fire. We investigate the incidence, risk factors, legal repercussions, preventive strategies, and the precise management of fires in the operating room, with a particular focus on plastic surgery procedures. In addition, we share insights from our own experiences and propose guidelines based on our findings to enhance safety and response measures in surgical settings. Fires most commonly occur around the head, neck, and upper chest. High-risk procedures include tonsillectomies, tracheostomies, laryngoscopies, and facial/neck surgeries. Checklists help ensure proper precautions are taken, like using moist towels and lowering oxygen concentration. If a fire erupts, prompt removal of the oxygen source and irrigation are critical. From our experience, fires spread rapidly and can cause severe burns and inhalation injuries. We share illustrative cases of surgical fires at our institution over the past decade. Our review underscores the importance of fire prevention and preparedness through safety protocols, equipment maintenance, staff training, and maintaining situational awareness. More research is needed to quantify risk factors and determine optimal management strategies when fires do occur.
