Your surgeon is correct. Restylane may be an option in some cases to fill in minor depressions as a non surgical revision rhinoplasty. Restylane to the nose is not permanent but the nonsurgical rhinoplasty injections are inexpensive and quick and may be easily repeated once or twice per year. Other options would be cartilage or fascia placement in an actual surgical revision rhinoplasty. Regardless, the nose continues to change throughout your life and slight contour irregularities may develop.
