title: Application of microautologous fat transplantation in the correction of sunken upper eyelid.
abstract: BACKGROUND
  Although fat grafting has been clinically applied by surgeons in esthetic and reconstructive surgery, it has widely evolved in processes such as harvesting, processing, and placement of fat, using the fat-grafting procedure, which dates back over 100 years. Surgeons frequently use fat grafting to recontour, augment, or fill soft-tissue defects, facial wrinkles, or skin problems such as depressions or scars. However, fat grafting has not been thoroughly understood and has not been conclusively standardized to ensure superior clinical results.
  
  
  METHODS
  This study was intended to determine the role of microautologous fat transplantation (MAFT) under evidence-based medicine, particularly in accurate delivery of small fat parcels. The research method involved the conceptualization of MAFT and the development of an innovative surgical instrument for fat placement. Clinically, 168 patients with sunken upper eyelids with multiple folds underwent this procedure.
  
  
  RESULTS
  The major findings suggested that MAFT exhibits promising clinical results and offers a superior guideline for fat placement. Details of the technique and theoretical implications are also discussed.
  
  
  CONCLUSIONS
  The therapeutic effects of MAFT and the long-term clinical results of patients with sunken upper eyelids with multiple folds indicated satisfactory outcomes. Based on the results, MAFT offers an alternative option to surgeons for performing fat grafting and provides a more favorable option for the benefit and welfare of patients by reducing the potential complications.
