Revision rhinoplasty experts how can I smoothen out my bridge and make my nose smaller? (Photos)

Hi @LK19! I recommend seeing a revision rhinoplasty specialist for an in person examination. There are several options for you that can be determined after examination. Rib harvesting is sometimes necessary in revisions if the septum and supporting cartilage of the nose have been weakened. This will give more strength and support to the nose. Rib harvesting is fairly simple and commonly used in revision procedures. Best wishes, Dr. Nima!

Really, more photos are needed to do a good online consultation like this. It's usually possible to improve those irregularities, but lots of different views would help in understanding what's going on there, and also, importantly, to see what other changes could be made, as you said, to make a smaller nose.I usually think that on revision, it's good to make a nose smaller if possible, because then any remaining bothersome asymmetries or irregularities reside on a smaller nose, and thus are smaller and less noticeable.
Remember also that 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. The changes that your nose needs require advanced techniques, and skill that most plastic surgeons don't possess with expertise. For most noses, it's much better to not have surgery than to have inexpertly-performed surgery. Read my essay on how to stay out of trouble while selecting a rhinoplasty surgeon. And for those who have had previous surgery, it also discusses how to tell whether your first surgeon should be performing your revision. And it also discusses how to take photos that are best for online evaluations.
Your nose is also a perfect 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. I always email morphs to my online rhinoplasty consultations. When you see the surgeon's goals in the morphs, 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 large 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? And additional, full-face images would be needed for that.

Cadaver cartilage has been used duct in many patients but it’s long term outcomes are still unknown.  I would be concerned about irregular absorption and so avoid it as an onlayngraft and only use for underlying support.   Using your own rib should be a permanent solution.   Rib grafts can look bulky, and there are solutions to avoid or correct that.   The irregularities are fairly obvious and will get worse over the years in all likelihood.   I would recommend a revision rhinoplasty with an experienced surgeon using your own rib cartilage and probably some fascia overlying your temporalis muscle which will not leave a visible scar.
