We narrow that arch by
placing sutures across the cartilage. The technique is diagrammatically
represented above. The black line represents the tip
cartilage, seen edge on from the base view, with the dome at the top. The red line is a
suture that we placed below the dome, connecting the columellar portion of the
cartilage with the lateral portion. When we tie that suture, shortening
the length of the red line, the columellar and lateral portions of the tip
cartilage are pulled closer to each other, and the arch at the dome is
tightened.

The photos above show
the first pass of the suture to accomplish this narrowing. The forceps
(green) at the top of the picture are holding the tip cartilage in a
tightened, narrowed position for the needle (white) and the thread (light
blue). The bottom edge of the tip cartilage is highlighted in red, showing
you the tightened arch of that cartilage.
