Many of the issues you describe (bleeding, infection, death) are risks of any surgery. This risk depends on patient health, type and length of procedure and the setting of the operation. Rhinoplasty is usually performed on healthy individuals under general anesthesia in an outpatient surgery center. In these cases, risk is exceptionally rare. You have to discuss your personal risk with your surgeon who knows your health status, etc. Risk of an undesired cosmetic outcome also depends on surgeon skill, specialization, and the complexity of the nose. Of course, patient expectations are also important since some patients may be unrealistic. In revisions, traumatic and congenitally disfigured noses, the risks are higher. Again, this is something to discuss with your surgeon who should be able to give you a clear assessment of your risk. Meet with at least two or three surgeons and determine who best communicates with you about your questions. Always go with a facial plastic surgeon or plastic surgeon who specializes at least 25% of their practice to rhinoplasty. Talk to others in your community who have had nasal surgery with the surgeon (although one may be a great breast or eyelid surgeon, noses are completely different). In general, the greatest risk a patient takes on the day of their surgery is in the car riding to and from the surgery center.
