So what does a prominent anterior nasal spine do to the appearance of the nose?  The person above has a typical large anterior nasal spine.  His anterior nasal spine is contributing to the excess projection of his nose, holding it too far forward, out away from his face.  In the after picture above, the nose has been deprojected back closer to his face.

He also has what we call "tethering" of the upper lip.  Compare the curve that the profile line of his upper lip makes in the before pictures above and the after pictures below.  I have traced that profile in blue on the diagrams at right.  The position of his prominent anterior nasal spine, under the skin, is drawn in black.

With tethering of the upper lip, as we trace the skin of the lip from the mouth up to the bottom of the nose, the lip's profile pulls forward in a curve until it blends with the base of the nose.  


In the after pictures, the upper lip is fairly straight, and it meets the bottom of the nose at a more distinct angle, instead of curving forward to reach the base of the nose.
