What is the safest way to remedy after a failed REVISION rhinoplasty?

Unfortunately, it looks like some more work is needed to smooth out the irregularities. A well performed revision should make a nice improvement, but it has to be done by someone with extensive experience. If you don't want surgery, then fillers and maybe silicone may be able to make a nice improvement.

You appear to have several indentations and irregularities, likely because you have thin nasal skin. If you are looking to avoid further surgery, depending on your examination, microdroplet Silikon-1000 maybe considered for achieving a smoother nasal appearance, however, this would not lead to a narrower nasal appearance. I hope this helps and I wish you well moving forward. Sincerely, Dr Joseph

When a surgeon misses your goals for your rhinoplasty by such a large margin, twice, there is a communication or conceptual problem there, and giving him a third opportunity is not reasonable -- there would be little chance for success. From this one photo, it does appear that improvements are possible. But you should also know that a third-time revision is quite difficult technically, and the great majority of plastic surgeons would not be able to approach the operation with expertise. So I wouldn't give up, but you need to re-vamp your method for choosing a surgeon, and definitely not use a surgeon based only on his verbal assurances or a referral from someone else or a board certification.
