What are the surgical procedures required to reshape the nose?

Depends what is done: The basic steps of rhinoplasty include incisions to access the tissues beneath the skin, modification of the bridge (removing bone or cartilage or building this area up), refining the tip of the nose (with sutures, adding cartilage or by removing cartilage) and modifying the nasal bones with precise cuts. The specific details really depend on what the nose looks like and the cosmetic goals.
