Is lower facelift less effective when done with chin bone shaving due to the amount of swelling? (Photos)

im scheduled to have FFS this summer, and this includes chin contouring by bone shaving method. My lower face has much laxity, jowls and underchin connent and make jawline very weak. My question is, would it be benefial to have a lower facelift at the same time as the chin bone shaving? I know with the chin contour there is a lot of swelling for some months after, and i worry that would affect the tightness and overall result of the lower facelift. Should i have the lift preformed after healing?
