Thank you for the question and pictures. Based on your photographs, you may be an excellent candidate for tummy tuck surgery at some point. Generally speaking, the “ideal” patient for tummy tuck surgery is one who has completed pregnancies, is medically/psycho socially/emotionally/financially stable, has an excellent social support system surrounding him/her, does not smoke, is capable of arranging enough recovery time and who has reached a long-term stable weight. Keep in mind, that tummy tuck surgery, of any kind, will not "get rid of" the previous (?cholecystectomy) scar. Also, patients who have had long transverse scars may experience problems with blood supply to the abdominal wall flap raised during tummy tuck surgery. A limited undermining tummy tuck operation (with the standard transverse incision) performed by a well-placed board-certified plastic surgeon will be your best bet. When it comes to cost of surgery, there may be many “variables” involved. The exact operation planned, the specific surgeon's credentials/experience level (or lack thereof), the specific geographic area you are looking at, the different operations available, the location of the procedure ( quality of surgery facility), type/quality of anesthesia provider… are some of the potential variables involved. You will find average costs of surgery listed on this website, and on individual plastic surgeon's websites as well. In regards to outcome of the planned procedure, more important than costs of the procedures will be careful selection of your plastic surgeon. I would suggest starting with the American Society of Plastic Surgery and/or the Aesthetic Society of Plastic Surgery to obtain a list of well experienced board-certified plastic surgeons. Then, I would suggest you visit a few surgeons whose practices concentrate on aesthetic surgery. ***Ask to SEE lots of examples of their work AND preferably speak/see patients who have had similar procedures done. Be very careful with your decision-making. You will find, while doing your due diligence, that there are many different “specialties” who will offer their services to you; again, I strongly recommend you concentrate on surgeons certified by the American Board of Plastic Surgery. When the time is right, seek consultation with well experienced board-certified plastic surgeons who can demonstrate significant experience (and safety record) achieving the types of outcomes you will be pleased with. Best wishes.
