Dear C, Cosmetic surgery is purely elective. You want the surgery rather than you have to have it medically. As such, cosmetic surgery should have the minimal complication rate as possible. In a recent article that was based on data from insurance company that covers only cosmetic surgery, the complication rate when combining Tummy tuck and other procedures is increased by 2 or 3 times. (when the combination is of tummy tuck and liposuction , the complication rate is X 10). Full tummy tuck surgery can range between 4-6 hours and face lift surgery can range between 3-5 hours or more if eyelids and neck surgery are included. According to the anesthesia literature, surgery that lasts over 6 hours , has significantly higher rate of complication. Finally, the quality of the surgical outcome of the combined 2 procedures can be significantly compromised due to surgeons physical and mental fatigue. The advantages of combining the 2 procedure are one recovery and cost saving. However, your safety is more important and additionally, if you have to have corrective surgery, those advantages disappear ! So, if you were my patient, I would have separated the 2 procedure into 2 sessions. Always, consult with experienced board certified plastic surgeons, who perform surgery in accredited surgery center for your safety. Most importantly, check the before and after pictures in the photo gallery, to make sure that they are numerous, consistent and attractive. Best of luck, Dr Widder
