Piece of Cartilage in Nostril After Rhinoplasty, Can this be Fixed? (photo)

This is sort of difficult to explain, but after rhinoplasty I've had a piece of something - seems like cartilage - in my left nostril. It runs down the inside of my nose like a scar, and the largest piece is bendable so it sticks out. Also, on the left side, there is a lack of 'growth' or support where the nostril meets the dividing skin between the two nostrils (hopefully that makes sense). What is going on here? Does this happen naturally to other rhino patients? Can it be fixed?
