Nora,
The answer is it would depend. I have done fat grafting for a nose on one occasion and it worked quite well, but it was a generalized depression from an injury and not a rhinoplasty defect. We would just have to look at your concerns and decide whether fat grafting would be an option. I have also used Restylane for post rhinoplasty defects. It works quite well, and while you do have to repeat the treatment it lasts about a year. Let us know if we can help you further.
