[Extra-periosteal mask-lift. Technical note].

Based on the work by Caix and Goin, it seemed logical to perform mask-lift by extra-periosteal dissection, as it is the adipose and cutaneous planes which are affected by age, while the periosteum is not distended. It is much more logical to directly displace the planes concerned by the operation rather than operating underneath the periosteum, a relatively poorly extensible barrier. Apart from the dangerous zone of the middle third of the zygoma, the frontal branch of the facial nerve is at no greater risk than during a forehead facelift. Extra-periosteal dissection does not raise any particular problems in the malomaxillary region.
