you could get more hypertrophic scarring than normal if i were you i would stock up on scar gel specifically strataderm to last the next 8 months and use it everyday post op, there are other things you could try like tretinoin, dermarolling with machine etc but the key thing is to do it while you are healing otherwise it will be harder to fix.
I would also make sure to use an oral corticosteroid for maybe 1 month or a few weeks post op like prendisone if you can get it prescribed while will also reduce the inflammation reaction to the surgery, trental is also used to limit scarring conditions like peyrnonies im sure it will also help post op but make sure you do it while you are healing
