In the before picture, the cartilages that form the tip of her nose are fully present.  Above the tip cartilages is the divot resulting from loss of some tissue in that area.  Above the divot, her nasal bones are in their normal position.

If you know where the nasal bones normally reside, you can see their outline in the before picture above.  If you'd like to find out more about the location of the nasal bones and how they are addressed during surgery, check out that chapter of the rhinoplasty surgery tutorial (the surgery tutorials contain explicit photographs taken during surgery).
