Current state and exploration of fat grafting

Fat grafting has become one of the most frequently used techniques in plastic and reconstructive surgery. Many studies have focused on optimizing procedures, such as donor site selection, harvesting, processing, and grafting. Representative basic techniques include Coleman’s and “3L3M” techniques. A new technique called compartment-based targeted fat grafting (CTFG) has gradually been established based on anatomical findings of the facial and hand compartments. CTFG achieved precise restoration of the fat volume in the anatomical state. Cell-based fat grafting has introduced new fields involving tissue repair and regeneration, including facial rejuvenation and scar improvement, among others. In this review, we summarize the timeline for the development of fat grafting
