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.
