Can Rhinoplasty be fatal? I know there is always a risk but is it classed as a dangerous procedure?

The 4 most important things that you should be aware of in order to have the least likely occurrence of a serious problem coming up during an operation would be the following: 1. Using a hospital based ambulatory surgical facility that has a good reputation in your area. 2. Having an excellent team of anesthesiologist who's abilities are well known to the surgeon. 3. Having an adequate and detailed preoperative medical clearance carried out in a timely way prior to the surgery. 4. If you do have any significant pre-existing medical conditions they should be treated if necessary and if necessary the surgery could be delayed or cancelled until those medical problems are adequately resolved so that they would now affect the outcome of your surgery. Such issues include checking for thyroid disease, bleeding tendencies and allergies to anesthesia and medications. 

In general, rhinoplasty is very safe and if you are healthy the risk is extremely low. Best of luck.
