The Anatomic Basis of Facial Aging and Facial Rejuvenation Techniques

Abstract

As we noted in the previous chapter, it is difficult to present a theory that encompasses all the changes that occur in the aging face. The different mechanisms causing these changes in each of the tissue planes are not yet known. However, the results of anatomic and radiologic studies have shown that it is a problem involving gravitational factors, the distention of supporting structures, changes in volume owing to bone resorption, and especially soft tissue atrophy and redistribution. In addition to these factors is the combination of different genetic factors and biochemical changes, which means that not everyone ages in the same way. The following summary enumerates the most significant changes that occur in the aging face.
