[Concept and technic of malleable subperiosteal onlay. Toward a new dimension in facial rejuvenation surgery].

We believe that rejuvenation of the shapes and volumes of the face is just as important as "tightening of the skin and muscles". In this way a more complete rejuvenation effect is obtained which is better perceived by others. The SMO technique provides a solution by the use of malleable coral microgranules, which may constitute the first biomaterial of a new generation of plastic and malleable onlays. In this context, a more general volumetric concept of ageing is developed, leading to a modification in our consultation and our treatment. Most importantly, this approach opens a whole new field, that of preventative treatment of facial ageing, which will no doubt be multidisciplinary.
