Thank you for your questions regarding a crescent arm lift, arm reduction, or brachioplasty. Based on your history of weight loss and genetic history of large arms, I would not suggest a crescent arm lift. I would STRONGLY suggest arm liposuction to be combined with a full brachioplasty. In your case, I would suggest an incision from the armpit to the elbow for full elimination of excess arm skin and fat. I believe if you just do arm liposuction with your weight loss history, genetic history, and current weight, that you would be left with excess, hanging arm skin. Therefore, your arm skin and fat needs to be removed. The crescent arm lift in your situation would not be enough. You need arm skin and fat removed from the armpit to the elbow. The cost depends on your geographic area. The best place to find the cost for a procedure in your area would be to use this website, RealSelf. Enter the location and procedure of your choice and local prices will appear. When seeking arm surgery please seek an arm lift specialist.
