[Conservative cervico-facial facelift. Concept and preliminary results].

A new cervico-facial facelift is presented, taking into account the cervico-facial cutaneomusculo-aponeurotic unit (CMAU) comprising skin, subcutaneous adipose tissue, superficial musculo-aponeurotic system and the particular mechanism of cervico-facial ageing. The undermining, limited to the parotido-masseretic region, is not subcutaneous, but immediately submusculoaponeurotic. The advantage of this facelift is to replace all of the CMAU over the underlying musculo-aponeurotic or osteo-periosteal planes, without modifying superficial relations. The cutaneous detachment preserves the natural appearance of the face and avoids the classical complications of facelift.
