If you had 3 rhinoplasties and still are unhappy, as I am sure you are, it may be more beneficial to have an experienced rhinoplasty surgeon evaluate you and give you another opinion about what to do. I have done many revision rhinoplasties and the anatomy is very different. After 3 operations, it can be even more difficult to fix the problems because of the scarring that is there. Good luck!
Revision rhinoplasty is one of the most challenging surgical procedures that there is for the rhinoplasty surgeon. A bump that persist for over 14 months postoperatively is unlikely to resolve and will require surgical correction. Without the surgical record, the ability to examine your nose and the operative report from your surgeon it is impossible to speculate on the cause of your bump. Scar tissue, a misplaced cartilage graft or cartilage graft that has been distorted by scarring are the most likely causes. I would ask your surgeon if grafts were used in your nose. If you decide to have your revision surgery done with a different surgeon make sure that you take copies of your operative notes and preoperative photos with you for the consultation. If the bump is scar tissue it may respond to steroid injections. This can be unpredictable and should be pursued with caution. Good Luck.
