[Midface region: functional anatomy, ageing process, indications and concentric malar lift].

Functional anatomy indicates the specificities of the most mobile zone of the face. Ageing process analysis, with the help of CT scan and MRI, confirm the validity of the Face recurve concept: the repetition of the contraction of certain fascicles of the mimic muscles is responsible for the deep fat diminution. For the first time, two fascicles of the orbicularis oculi muscle, malar part, are demonstrated to cause the recession of the inferior orbital rim and of the mid part of the malar bone. Medical and surgical indications are differenciated, depending on the palpebral and midface skin excess. In case of noticeable skin excess, the concentric malar lift can remove vertically the major part of it, reposition the deep and superficial fat at it's original location and weaken the age marker fascicles. Restoration of the periorbital bone volume could be a challenge in the future.
