How Likely Will Potentially Deadly Risks from Rhinoplasty Occur?

Hi Tiger Fan,
Are those the LSU or Auburn Tigers? I think I know Coach Miles.
The risks that you are concerned with are miniscule. In today's litigious and greedy society it is necessary to cover all of the possible untoward events that may occur when undergoing any type of procedure. There have been incidents where a surgery is cancelled for one reason or another, the patient is at home at the time of the scheduled surgery, and suffers a coincidental fatal heart attack. Fortunately the benefits of your rhinoplasty surgery will far outweigh the very remote risk of the complications that concern you on your informed consent.
As surgeons we wish that we could give every patient a 100% guarantee, but for the complications that you are concerned about, it's just under 100%, in the 99% range. The only thing that surgeons can guarantee is that they will show up for your surgery, and even that is not 100% as I had a colleague who suffered chest pain on his way to the operating, and had a small myocardial infarction himself.
If you are in the hands of a competent, well trained surgeon, you minimize your risks to the point where you need not worry about them. As comedian George Burns answered his heart surgeon just before his bypass to the question, "Mr. Burns, you look so relaxed for someone about to undergo surgery, are you worried?"...."No sir, I'm going to be asleep, you're the one who should be worried"
Be well and enjoy your new nose.

The risk of complications and death following rhinoplasty surgery is extremely low.  This is especially true if the procedure is performed in a fully accredited certified outpatient surgery facility with an anesthesiologist in attendance.  The safety margin is even better when the procedure is performed by a board certified plastic surgeon.  

I have successfully performed hundreds of rhinoplasty surgeries throughout my career, and, luckily, have not encountered a single instance when a risk of death was present. Still, it is important to be in good overall health before committing to a rhinoplasty. Any health issues that are hereditary should be clearly translated to your doctor. If you are concerned primarily after signing off on the list of complications that you mentioned, this is a common practice that many physicians require of their patients before operating and should not be a reason for worry.
