How soon after rhinoplasty can I get injectable filler in my nose?

In general, fillers in the nose within 6 months of a rhinoplasty procedure are not a good idea at all. Preferably, patients would wait 12 months to see the final results of a rhinoplasty before considering ANY additional treatment, including surgery. Fillers can work well to camouflage a dorsal hump, augment different areas of the nose, correct small asymmetries, etc, but do not work well to correct a severely crooked nose, especially a crooked tip.
I also agree that fillers in the nose are not a good idea if a revision rhinoplasty is considered any time soon. I perform quite a few non-surgical nose jobs, but would probably recommend against it in this case.
Be sure to discuss your concerns with your surgeon, and be patient during the healing process.
All the best,

I would recommend you seek consultation with a board certified facial plastic surgeon or general plastic surgeon who specializes in revision rhinoplasty.  This is not a situation to jump into hastily, and filler may or may not be the answer.  Filler when used in “nonsurgical rhinoplasty” can camouflage small irregularities (think spackle when painting a wall) but generally cannot be used to correct large deformities like you describe.
Best Wishes.

You should not get fillers on nosed. Let everything settle and get revisional advice from your surgeon. Rhinoplasty revisions are not very predictable.
