Hello, That is a great question. A good surgeon for revision rhinoplasty is one who has first mastered primary rhinoplasty, then extended their knowledge to the issues that can go wrong and how to fix them. There is no certifications or badges for those who excel in revisions. In fact, having certain credentials doesn't guarantee a surgeon is good at rhinoplasty, it just ensure they have gone through the initial parts of adequate training. The mastery of this difficult surgery comes from continued hard work, care, and certain innate abilities. For any rhinoplasty, step one is to find someone board certified in either facial plastic surgery or plastic surgery, this will help narrow it down. Step 2 is to make sure they are truly a rhinoplasty specialists. Rhinoplasty should be a major part of their practice. This also does not ensure you are getting the right surgeon and some may do high volume, low quality... but again this is how you continue to narrow it down. The next step is to look through their web content, photo galleries, reviews, etc .... and see who you feel has the highest level of expertise. The last step is go to several consultations and evaluate the surgeons. Learn from what they are telling you. Get a feel for their feedbacks and knowledge. Compare what they tell you. Ask what their experience is with revisions and what level of satisfaction they have seen. See if they can show you an example of a similar case to yours. See if they are genuinely interested in achieving the best possible results. Then choose the one you feel most comfortable with based on all the information. Since you are looking at a revision, also think of what went wrong with the primary surgeon choice.Good luck!
