The revision rate for even the best surgeons is 10-20%. I didn't realize it was so high before surgery. I went to a top surgeon and still need a small revision (shaving the bone down on one side with possible second osteotomy). We all tell ourselves that it won't happen to us or that if we go to the BEST surgeon it won't happen, but it still can. Unfortunately, even if you've healed well from surgery before, you may not heal well after rhinoplasty.
Some forms of rhinoplasty are more predictable than others. A tip-plasty without osteotomy (bones broken) may be relatively reliable. However, having an osteotomy as I did can increase your risk for complications. My bones didn't heal properly although they looked fine after cast removal and now I still have soreness many months later.
While it's important to do your homework, know that you may still need a "touch up" as 10-20% of all rhinoplasty patients do within 2 years after surgery. The lowest revision rate that I've ever heard of is 7% for one particular surgeon but he uses silicone filler to correct asymmetry and doesn't consider that a revision. Be prepared for it to not be a one-step process. Although I know 5 colleagues that had perfect surgeries with my surgeon, my nose was the one that didn't heal well. Even the best surgeons have patient that don't heal well. It's a myth to believe that going to the best, most experienced surgeon will ensure that you heal without problems.
