Fillers can help to temporarily correct a mildly crooked nose. However, you should get a proper assessment by a certified and experience aesthetic Dr who will be able to tell you all the options available and whether in your case, it is amenable to augmentation with fillers. For an extremely deviated nose, the best option is often surgical rhinoplasty.
Another option that can help to augment the nose is nose threads, which can be used singly or in combination with nose fillers. Both fillers and nose threads are not permanent. Nose threads last about 9-12 months,and depending on the type of filler used, nose fillers can last from 9-18 months.
