Revision Rhinoplasty and Doctor
You can use your previous surgeon or another one if you like. The most important item is that the person who does your rhinoplasty is a revision rhinoplasty specialist. Almost a third of all rhinoplasties in the US have to be redone; however, revision rhinoplasty surgeons have a much lower rate (but they still have one). If you have a relationship with your previous surgeon, and you trust him, and if he feels comfortable with a revision rhinoplasty, then he might be fine. Do your research and see if there are others in your area and interview a couple of others to get a better feel.
Assuming your original surgeon is still in practice, he or she would best know your current anatomy since they've been there before. However, second opinions and consultation with other surgeons may reveal newer techniques or strategies that could only help you make a better decision to proceed. You want to optimize your choices and results with as much information and research you can reasonably obtain before committing to any procedure. This is perhaps the best way to prevent regrets afterwards.
