The revision will only involve adjusting the tip and the size of the nostrils.
In NYC a tip rhinoplasty is probably between $6000-$10000, but that is a range. Every surgeon is different.
Tip work is often rather complicated and revisional work is always harder than the primary procedure from the surgeon's point of view. This is not typically a discounted area even though the size of the "real estate" is rather small. Since this is a revision, it points up the importance of finding someone with the same vision as you and whose plan seems well considered and unhurried. Unfortunately, I would not expect to find a price lower than what you paid initially.
