Anatomie du vieillissement craniofacial

Abstract

The aging of the face is not limited to the cutaneous ptosis. There are changes interesting the sub-cutaneous tissues, masticators muscles and facial skull. The cutaneous aging is characterized by a skin atrophy and a loss of elasticity. The superficial musculo-aponevrotic system get loose as the orbital septum. Some cutaneous muscles are invaded by sub-cutaneous fat and the masseter muscle shows thicked aponeurosis. Maxilla and mandible aging is caused by edentulousness. There is a bone resorption and a loss of height of the lower third of the face.
