Because it has been six months since the rhinoplasty surgery, most likely there are not going to be any automatic major improvements. Now, it is wise to wait a few months more if there is any question; it is not wrong to wait up to a year.
However, has your plastic surgeon considered the possibility that a nonsurgical revision rhinoplasty, consisting of using a filler to correct a depression, might not suffice? Without seeing you, it is difficult to tell. If the main problem is that some cartilage is "too high," the filler may not be appropriate because it might make the adjacent area too large.
However, if, in reality, one area is high because the adjacent area is low, then there is wisdom in filling the lower area to see if it meets the heights of the high area. The mountain looks shorter if you fill the valley next to it.
You should consider that and discuss it with your rhinoplasty surgeon. You could even have a "saline demo," whereby sterile saltwater, the same type that is used for intravenous infusions, is injected to show the predicted result of the ultimate filling. The saline will dissipate within an hour or two, but at least while it is there you will have a good idea if success can be achieved without another surgical session. It makes sense because:
It is an in-office procedure
There is no downtime
The results are what you see
Less guesswork is in play
Injection rhinoplasty not be appropriate for you, but it is something that you should consider.
