Why not to use injectable fillers for a Nose Job

 I’ve heard that injectable fillers can be used for rhinoplasty instead of surgery. However, it sounds like a lot of surgeons don’t support this. Is there some reason why this may be so and are there ever times when non-surgical rhinoplasty with fillers can be a good option?
 
The only time I suggest a non surgical nose job is when the bridge height needs to be built up conservatively or small depressions filled after a previous rhinoplasty.  Large amount of fillers should not be injected into the nose in order to not risk scarring or infection.  Permanent fillers should also be avoided during non surgical rhinoplasty for the same reason.
