Pay attention to the white dots on the tip of the nose and to the more subtle white highlights on the nose in between her eyes.  Those dots and highlights are reflections from the flash.  The white dots on the tip are just a bit higher in position in the after picture, indicating that the tip of the nose was elevated during surgery.

In the after picture, the white highlights on her nose between her eyes flow down onto the nose a small distance, allowing you to see that her nose is narrow in the mid-dorsum.  In the before picture, you see less of those highlights flowing down the nose, because the before nose is wider and less angular.

The base view of her nose, view 9, also illustrates the narrowing of her nose quite well.
