Seroma after breast reduction
Seromas after breast reduction, or any surgery, are very frustrating. It sounds like you are now left with a seroma cavity that needs to heal. Packing it with iodoform is a fine so long as it is helping and the drainage is slowing and the cavity is getting smaller. Getting an ultrasound at this point will only confirm the existence of fluid in there. If this is not getting better, it may be time to have a "washout" of the cavity. You would be taken back to the OR, the area would be re-opened, the seroma capsule that is there would be removed, the tissues would be debrided and re-closed, likely over a drain. I would not attribute this to poor surgery skills, as all plastic surgeons get seromas. However, if it is never a bad idea to seek a second or third opinion.
