ABSTRACT
The aging process affects all the tissues of the face in different ways. The skin loses elasticity, fat reabsorbs, muscles lose tone and volume, and the bone loses volume, which leads to descent and increasing laxity of the overlying soft tissues that rely on it for support. Based on this knowledge, the most effective method of facial rejuvenation would also include restoring lost bony volume. While there is yet one satisfactory means of achieving this, an alternative is to restore the conditions of the soft tissues and the relationship between the soft tissues and the existing skeletal volume. To achieve this effectively, a deep plane approach is required.
