Otoplasty reversal - should I do a skin or cartilage graft? (photos)

Dear madam ,sir i had an otoplasty about 4 years ago and my ears were overcorrected , my surgeon said its hard to fix so i saw some others surgeons and they suggest two different ways to go 1.skin graft 2.cartilage graft so i m confused which way to go bcoz i ve heard skin graft might leave too much scars but according to few docs its the only way at my case as all skin was revomed at privios surgery
