LAM FACIAL PLASTICS

Hi, Dr. Lam. I'm an asian patient that had twice rhinoplasty surgeries and a lower lip reduction within 3 years. At first the surgeon recommended me to take some of the cartilage from the right ear to rebuild the bridge to taller ,and reshape my bigger nose tip. A year later, the result wasn't what I expected. I went back to have the second surgery to had my nose look more straight and have a higher bridge. This time the surgeon took some of the cartilage from my rib, also there are two to three pins are still inside my nose to support the bridge and hold up the tip. The final result wasn't really satisfied me still.
Now, there is my questions: 
1) now i can feel a thumb sized dent in the right on the top of the bridge and my nose leans to the left right top of the bridge. When the time I got second  nose job done, there was a plaster cast stick on the bridge to straighten it. I knew it there was a fingerprint pressed on the top of the cast on my nose.
do you think was it a mistake that the cast was squeezed too much on the right side by someone who put it on?
2)If so, could it fix by revision? 
3)Do you think how many percentage of  human error occur on this kind of situation?

Thank you very much!

do you think was it a mistake that the cast was squeezed too much on the right side by someone who put it on? i can't say because i was not there but i always say i do not treat feel but i treat look. in other words if you can principally feel it then that is something i do not think is worth managing it.
2)If so, could it fix by revision? sure, but it could probably more easily fixed with an injectable, whether temporary or permanent.
3)Do you think how many percentage of human error occur on this kind of situation? truly i have no idea in your case.
