Surgical literature is severely lacking in anatomo-clinical descriptions of facial aging. Only a few authors provide minor reports on the pathophysiology of aging in order to propose methods of correction. It therefore appears important to start with a diagnosis of the lesions as precise as possible in order to be able to perform the most appropriate treatment. We propose a semeiological analysis of the face, not only stage by stage but layer by layer, starting with the skin, then the fat, muscle and bone. We will then consider the methods which appear to be the most suitable for correction of the various structures concerned by aging within the framework of a total facial reorganisation. We will conclude with a presentation of surgical cases describing the surgical techniques used, with respect to a semiological analysis from each case.
