[Facial fat: descriptive and functional anatomy, from a review of literature and dissections of 10 split-faces].

The aim of this study is to describe the anatomy of the fat in the face, based on a review of the literature and dissections of 10 half-faces. The facial fat can be divided in two layers. The first-one is superficial, between the skin and the superficialis fascia. Its function is essentially protective and its morphological implications are major, especially according to the facial aging. The other layer is deep, under the superficialis fascia. Its principal function is mechanical and its morphological implications are less important. This layer is made of several fat pads in continuity, excepted the buccal fat pad which is separated from the others by its own capsula. The other fat pads are the intra orbialis fat pad, the sub orbicularis oculi fat pad (SOOF), the retro orbicularis oculi fat pad (ROOF), the galeal fat pad and the temporal fat pad.
