First of all, I am very sorry you have to deal with this. I am sure this is very stressful and disappointing.
I understand how unhappy you must be. You don't walk to walk around feeling very self conscious about your nose. Given this, the only reasonable option for you is to have a temporary filler injected so that the scoop deformity of your nose is covered. Make sure that a temporary filler is used, and not something like Radiesse which will last a long time.
I usually wait 6 -12 months before I will perform a revision on somone who had a deformity caused by another surgeon. Yes, 12 months would be ideal. However, I also consider the emotional distress experienced by the patient. If it is something that is an obvious deformity, I believe it deserves earlier intervention.
The injection of the fillers should be timed so that it will be absorbed by the time you are ready for a revision. Then, a permanent solution to your problem, such as a graft, can be used.
