People are always worried about what it will look like and that is understandable. The cosmetic result will vary a bit based on the skill of your surgeon. There is a bit of an art to it. I think my son's butt looks normal. His crack might look slightly shifted at the top. It's hard to explain and I don't have pictures. You will want to make sure you find a surgeon who people on this site have vouched for. That is your safest bet. The recovery time is different based on the severity of the disease and the location of the cysts and sinuses. All problem areas will be corrected in the surgery. It sounds like your son may be on the easier side in terms of recovery. I would think after two weeks he should be feeling pretty good.
