Pros and cons of fat injection in the nose?

Fat is a large particle. I have not used it to soften irregularities after nose surgery. The filler I like is Juvedrem Ultra. This filler is placed carefully with a very small needle, allowing for very exact placement. If a patient chews through it, meaning it does not last very long, I would suggest using the Juvederm Ultra Plus. I would seek out an experienced injector in your area, As a national trainer for Allergan I have taught Doctors and nurses from around the world on how to use fillers, this is definitely more of an advanced procedure. The scar may respond to the filler or may need a revision. If considering a revision, I would wait a year from your initial surgery.

Fat graft to the nose are not ideal. A filler like Radiesse, Bellafill, Restylane or Juvederm would be a better option. See link below for examples

Fat might be a bit tricky to work with in the nose. I often will use HA's like restylane or perlane to modify irregularities.

Fat transfer will most likely be of limited usefulness for what you described. Fillers may be a much better option. Fat transfer is an excellent choice for giving overall diffused volume enhancement, but it is not nearly as effective for small-sized contour corrections.Sometimes more definitive procedures, including cartilage grafting, which is a more standard approach in revision rhinoplasty surgery, are better options.  I suggest getting a second opinion from a board-certified plastic surgeon who specializes in rhinoplasty surgery. Secondary rhinoplasty surgery can be one of the most complex and difficult procedures to perform.Best of luck,Mats Hagstrom, M.D.

Fat transfer is not a very good solution in most cases, due to poor "take" problems. Many other filler options exist, as well as minor revision surgery. The columellar scar can be revised if it has been at least 6 to 12 months since the original procedure. Hope this helps!
