This book deals with a special form of facial rejuvenative surgery, which considers the three-dimensional anatomy of the face and benchmarks it against biomechanical models of the face. Traditional approaches to the ageing human face have been based on a two-dimensional approach. The authors, however, consider the human face using a three-dimensional platform that reflects height, width and depth and thus defines spatial divisions or pilasters. The anatomically accurate and bio-physically based three-dimensional computational models, originally used to simulate facial expressions and subsequently in the dynamic evaluation of the various soft tissues, offer a valuable new tool for surgical techniques.
