Hi Poetsjasmine, Thank you for your question regarding how common are serious complications like necrosis after a full brachioplasty (armpit to elbow). Complications can occur with any type of surgery including an arm lift or brachioplasty. Necrosis is a medical term to describe cell death. Fortunately, necrosis is VERY rare after a full brachioplasty. Complications after an arm lift include wound break-down, bleeding, infection, numbness, seroma, hematoma, prolonged swelling (edema), lymphedema, restricted arm movement (tightness), asymmetry and poor scarring. These complications are much more common than necrosis. To minimize risks of all these potential complications including necrosis, you can take proactive steps. Please seek an experienced, board certified plastic surgeon with significant experience performing arm lifts. Do your research. Make sure they have performed at least 150 arm lift procedures. Make sure they have the before-and-after pictures to prove it. Carefully examine their before-and-after pictures and check their reviews on RealSelf. To minimize complications, after your arm lift, you must follow your plastic surgeons recommendations. Most complications can be avoided if you closely follow their post-op instructions. I hope that I have answered your questions regarding necrosis after an arm reduction. If you have any more questions regarding the arm lift, arm reduction, brachioplasty or arm crease fat grafting, contact an experienced plastic surgeon.
