Slightly Asymmetric / Palpable Cheek Implants - How Difficult to Revise?

Had the surgery done only a few days ago, midface rim implant. RHS implant is almost imperceptable to touch & hard to know where bone ends/implant starts, which is great. Inner edge of LHS however is quite palpable near inner nose which suggests non swelling related asymetry. LHS seems to be higher than RHS, and I think I can see it through the skin. How difficult is it to revise? Implant is medpor and screwed in. With Local anes possible? Would swelling be same as orig surg?
