What risks can occur by fixing a crooked nose in rhinoplasty? (Photo)

After my rhinoplasty a few years ago My nose from the front is crooked/dented to the left side with asymetrical nostrils I also have breathing issues I want to get a revison to fix my nose from the front but I heard that it’s very difficult to fix a crooked nose, I’m afraid it will get worse And I get unpredictable issues Like bumps, increased Internal scar tissues, fibrosis pollybeak, perforation etc. Are my concerns justified?
