Scar revision and keloid removal 1 year after breast lift with implants - Nipple sensitivity? Suture options? (photos)

I had a breast lift + implants over a year ago. Although I am satisfied with size and lift position of my breasts, my scar did not heal properly. Throughout recovery, I developed multiple wounds along my areola and vertical scar, giving my scars a wide appearance. I was told I could have had a reaction to the dissolvable sutures. I also keloid on the bottom horizontal scar. I want to have my scars revised. Would I lose sensitivity in nipple area? Will I scar the same? Other suture options?
