In the before picture, you can see some white marks in the middle of her dorsum that are reflections from the flash, right where the hump was.  The marks are crooked, indicating that her nose was a little crooked in that area before surgery.  I mentioned in the section on nasal reconstruction that correcting a crooked nose is one of the hardest changes to make in rhinoplasty.  However, if the crooked area is small, and if it's on the hump, sometimes simply removing the hump removes the crookedness entirely.

We also know that her nose was shortened somewhat during her rhinoplasty, because we get a better view of her nostrils in the after picture.
