Preoperative evaluation and surgical details of chin fat augmentation aiming at increasing the projection of the original mentum are scarcely reported. Herein, the authors systematically reviewed the application of fat grafting for chin augmentation in our institution from 2010 to 2014. This percutaneously multilayered fat-injection technology can be applied for chin augmentation for a subset of patients after strict selection, and the details of lipofilling technology and fat distribution vary depending on each individual patient's condition. Mentum can be augmented in the sagittal plane in different degrees, whereas the chin height seems unable to be effectively prolonged by lipofilling.
