[Subperiosteal face lift or "mask-lift"].

The subperiosteal facelift is, as its name indicates, a deep technique essentially adapted to the upper two-thirds of the face. It is performed via a bicoronal incision, often associated with a vestibular incision, which allows frontal, maxillary, malar, zygomatic and orbital dissection. Section of the superficial leaflet of the temporal aponeurosis reveals the DMAS (Deep Musculo Aponeurotic System) which can be used to raise all of the soft tissues of the face while protecting the frontal branch of the facial nerve. Elevation of the tissues of the face is essentially vertical and acts on the forehead, temporal region, gaze and cheekbones. Current incisions allow maximal preservation of hair and avoid ascension of the sideburns. This technique is particularly indicated in relatively young subjects.
