Too Soon to Have Rhinoplasty After Non-surgical Nose Job?

The Radiesse may have dissolved, but if not your surgeon may see it during your rhinoplasty.  It would probably be okay to go ahead with the procedure, just make sure the Radiesse is replaced with cartilage or bone during the rhinoplasty.  Good luck!

Rhinoplasty requires accurate evaluation of nasal contours at the time of surgery to obtain the desired result and the difference of a millimeter or two is noticable. Radiesse usually lasts about a year in relatively immobile locations such as the nose and I would advise waiting the full year to avoid any unexpected contour changes later.

I would wait until the product has dissipated fully. This may take 9 to 18 months. Having surgery prior to this will make it difficult for your surgeon to determine the proper height of the graft. Waiting will lead to a more successful surgical outcome.
It would be difficult if not impossible to remove the particles after injection as they would be dispersed in the tissues of the skin.
