The techniques of the midface rejuvenation develop with the understanding of the aging appearance and the development of the facial anatomy. The earliest form of rhytidectomy only removed a piece of redundant skin, but failed to achieve significant long-term benefit. To achieve a more durable benefit, numerous adaptations of face-lift techniques are devised, including SMAS face-lift, malar fat elevation and extended supraplastysmal plane face lift.
