Above left we see the
situation after removing the hump. The skin was not disturbed. The
bone and cartilage comprising the hump were taken off.
But see what
happens if we were just to quit there: the skin, when it conforms to the
new shape of the nose, will show an unattractive flat spot along the
dorsum. The nose now looks too wide, and all we did was to take off the hump.
The mathematicians
would say that a cross section of the nose has the approximate shape of a
triangle, and by taking off the hump we have truncated that triangle,
leaving ourselves with only the wide base. We now need to narrow that wide
base so the nose doesn't look too wide when we are done with surgery.
