Is it worth getting a second rhinoplasty to make my nose even smaller? (Photo)

Hello,
Thanks for your question. Looking at your photos, it may not be possible to safely reduce the size of your nose further without compromising something important. Your skin looks like it may be fairly thick, but that could only be confirmed in person. Scar and changes in blood supply may limit how small the nose can go. If you seek revision rhinoplasty, make sure you work with a specialist in revision rhinoplasty to have the best chance of getting close to what you want. Good luck,Dr. Shah

I made a computer morph of your nose, and an animation of the morph, to show the changes that are possible for your nose in truly expert hands.
Generally, if your nose has a basically good shape, it's not worth doing a revision to make a tiny tweak. But if you wanted a bigger change, such as elevating the tip noticeably, and bringing the tip back closer to the face, and lowering the bridge, then those changes together would add up to a difference that you might consider worthwhile.
I tried to make a morph to show some of that, but really, a photo of a nose needs to have the entire face in it, for context. The nose is part of the face and the face helps to show what the nose should look like.Did the morph seem to address your main concerns? I could modify it to your taste if you wish. Some people might want more of a distinct concavity in the bridge, for example.
You should understand that the changes I demonstrated in my morph try require advanced techniques, techniques that most plastic surgeons cannot handle.  Be sure to read the section in the "Learn more" link on how to stay out of trouble while searching for a rhinoplasty surgeon, and read the essay on how to tell whether your previous surgeon should be performing your revision. Rhinoplasty is an exquisitely difficult operation to get right, and you should only have surgery if you are able to make yourself very confident in your surgeon's skills. 
Your nose is also a good example of why computer imaging is mandatory in rhinoplasty. You need to know exactly what the surgeon is planning to accomplish -- what features he thinks he can change, and by how much he thinks he can change them. When you see his goals, you'll know whether he has an eye for an attractive nose, and whether he shares your opinion of what constitutes an attractive nose. You'll also know whether the changes he proposes are enough to be meaningful to you, and whether he understands your wishes enough to address all of your priorities. How would you ever get that figured out without the morphs?! But remember, you're not hiring him for his skills with the computer. The doctor must then show you his before and after photos to prove that he can actually accomplish what he draws on the computer.
In your case in particular, you need to find a surgeon who understands all of the issues I mentioned, and how they fit together, and who can actually accomplish them in surgery. 
Finally, at the *very* bottom of the "Learn more" page is a link to instructions on taking and sending photos that are comprehensive and useful for an online consultation like this, in case you'd like a more complete evaluation.
