Contrary to what most surgeons think, revision rhinoplasty can be performed very soon after the initial surgery.
If there is a gross deformity, there is absolutely no reason to wait. This could be a poorly placed nasal implant, obvious crooked nose, inadequate reduction of dorsal cartilage or other circumstances.
If, on the other hand, you have a minor problem such as prolonged swelling or mild asymmetry, I agree that it is better to wait 6 to 12 months.
For gross abnormalities, I have performed successful revision as soon as 1 month after the initial surgery.
Looking at your frontal photo, I can see that you most likely have a "Polly beak deformity" which is a common mistake in rhinoplasty. Polly beak is when not enough cartilage is removed from the lower part of your bridge and your profile looks like a parrot beak , hence Polly beak deformity. Also the tip cartilages need to be revised. This is a situation, waiting will not do anything but prolong your frustration. This can be revised as early as 1 month post op.
Hope this helps,
