Injectable cartilage shaving to correct surface irregularities caused by revision rhinoplasty?

I am not aware of surgeons in the USA injecting fine pieces of cartilage to correct surface irregularities. I have had good success with fat grafting to correct minor irregularities, which I prefer to filler because it is long lasting.  Conceptually the idea is interesting of injecting cartilage particles, but in practice I have concerns about how predictable the results are.  For significant irregularities an open approach with diced cartilage in a  fascia wrap would be more predictable.

Crushed, diced, and shaved cartilage has been used for years to help improve irregularities in the nose for revision rhinoplasty. What is newer these days is injectable filler material, such as Restylane (hyaluronic acid), that is being used in the office as a tool in primary and revision rhinoplasty. Any rhinoplasty with cartilage is surgery, whereas the injectable fillers is non-surgical.If you haven't already, then speak with a plastic surgeon to help determine appropriate options for you.Best,Dr. Chaboki

I know of no specific surgeons using this technique in the US.  Most would recommend for minor irregularities some sort of filler.

 The concept of using finely diced cartilage in rhinoplasty has been around for quite some time.  In recent years, we have been expanding the repertoire for this procedure in a variety of ways.   I have been using finely diced cartilage often with autologous fascia to smooth out irregularities along to bridge of the nose for many years.  Personally, I prefer the surgical approach to do so rather than an injectable approach. I feel this affords me greater control over the outcome
