'Unstable nose'. Are there any options to reduce the size?

Hello! I underwent rhinoplasty 4 years ago, because I didn't like the straightness and size of my nose. I was very excited before the surgery, but superdisappointed afterwards. My nose still looked the same. Although I tried to accept this, I'm still super unhappy with my nose. I contacted the clinic and they said that the instability of my nose was the reason why they couldn't do anything. Is this really possible? If yes, are there other options to reduce the size of my nose?
