Q: Would it be possible for cartilage to grow back? How does an ear look after the harvest?
A: When properly performed, ear cartilage harvest results in little to no change in appearance to the ear. The incision can be hidden in a crease behind the ear, and cartilage only from the center – which does not alter size, shape or appearance – is harvested.
