Summary: The chin makes up the central unit of the face and neck, and is a significant factor in facial harmony and aesthetics. Historically, correction of microgenia required surgical intervention with a sliding genioplasty, or placement of a permanent implant. However, these techniques require more extensive surgical intervention, prolonged downtime, with higher costs and complications. Furthermore, chin rhytides and descent of chin fat lead to an aged appearance of the chin and lower face that is difficult to correct with a chin implant alone. Autologous fat grafting in facial rejuvenation has expanded in its application and can serve as an effective technique to correct and enhance chin aesthetics, including lateral chin hollowing, asymmetry, mild microgenia, and correction of deep labiomental sulcus or a bifid chin. This article and accompanying video demonstrate the authors' technique for chin augmentation and refinement with autologous fat.
