A 2-millimeter-wide
chisel is introduced, and the first of the two cuts in the right nasal bone is
being made, corresponding to the black arrow in the diagram at the top of this
page. The chisel cut starts at the midline, and extending into the bony pyramid. In the diagram, the bone is pink and the cartilaginous pyramid
is blue.
You learned a little
earlier in this chapter that we remove
the hump before performing the osteotomy. You can tell that
the hump has already been taken off in these pictures because we have an excellent view of
the top, or dorsal surface, of the septum, highlighted in white in the diagram
above right. Compare these two images with the two pictures just above
them, in the middle of the page. In the previous two photos, which show
the nose right after skeletonization but before removing the hump, the septum is not yet visible, because the hump hasn't been taken off to
expose the septum yet.
