The Scientific and Clinical Evidence Supporting Limited Delamination, Extended Deep-Plane Rhytidectomy: Introducing a New Paradigm-The 3-Zone Biomechanical System of the Face.

Objective comparison of facial rejuvenation techniques has remained challenging. This paper aims to integrate evolutionary, anatomic, histologic, and biomechanical evidence to support the limited delamination, extended deep-plane rhytidectomy technique. In addition, the paper introduces a novel 3-zone biomechanical system to understand the behavior of the face challenging the antiquated 5-layer model. It discusses the benefits of limited delamination, a variable, lateral deep-plane entry point, and the importance of different soft tissue types in facial rejuvenation surgery. Overall, the limited delamination, extended deep-plane rhytidectomy represents the most anatomically correct methodology for reversing facial aging.
