[Anatomical basis for rejuvenation surgery]

The understanding of the face anatomy is mandatory before to be able to appreciate the different surgical techniques of face lifting. Despite numerous controversies and anatomical variations, we can find in the literature several keystone works that allows us to understand that the soft tissues of the face are not only a superposition of layers but also a tridimensionnal structure with a fibrous system that links the different layers. This structures creates a mix loose spaces, fat and retaining ligament that can be describe in a quite systematic manner. This systematisation can help the surgeon during the surgical procedure to search and find the area where there is no danger and alert him around the retaining for example, which is where we can often find a vessel or a branch of the facial nerve that we want to avoid. This article summarizes these anatomical knowledge.
