Revision surgery is unusual but may be desired for several reasons. Most revisions should be done after 9-12 months. One cause for revision surgery are “dog ears” at the ends of the incisions. These are small folds of excess skin that do not flatten over time. They can be excised, suctioned or both. Now, since you are well past this 12 month period there should be plenty of availability for a revision. Scars may widen or continue to be red and elevated. These may require laser treatment or injection with kenalog and 5-FU. Excision and reclosure may help some scars. Other treatments are available as well. Excess fat or loose skin may require liposuction and skin excision to obtain the best result. Now, the best thing to do would be to seek out a local board certified plastic surgeon for a consultation on what procedures would provide the best results that you are looking for. Good luck.
