The soft tissue should also be reduced when doing a Chin reduction? (photos)

I've been to 4 plastic surgeons in Seoul, for consults and all have said it's unnecessary to remove the excess tissue when doing chin reduction. But I believe I have a lot of tissue on the ball of my chin, it's obvious when I smile and protrudes from my chin. From these pictures, I'd like another opinion, if possible. Should I trust them? Maybe they just have a different style than in the USA? If I follow through with the surgery here, how difficult is removing the tissue later, if need be?
