What are the risks or complications involved in rhinoplasty (nose reshaping)?

Any surgical procedure carries with it three types of problems. The first is related to anesthesia; general, and less commonly local. The second category is common to all surgical procedures. This is the risk of bleeding, infection, loss of soft tissue, loss of skin, numbness, etc. The third is specific to the particular surgery being performed. In the case of rhinoplasty, this would be asymmetry, changes in appearance over time, etc.
