“The facial skeleton defines the proportions of the face, soft tissues define the facial contour”
Profile correction procedures deal with changes in the projection of prominent areas of the facial skeleton as forehead, nose, cheekbone (malar bone) and chin. Profile correction may be required by augmentative or reductive measures. The entire forward or backward movement of the facial skeleton as the upper jaw, lower jaw, but also chin, cheekbone and orbit is possible. The nose is an independent unit that can be corrected by an open or a closed approach (see Aesthetic plastic surgery of the face). The chin correction (sliding genioplasty) allows forward or backward movement and is often combined with rhinoplasty. The art of a natural and outstanding result is the holistic consideration of the proportions of the face.
