Hello, Thank you for your question regarding how long you should keep your arms elevated after an arm lift or brachioplasty. Arm elevation is important to decrease arm edema or swelling. Since the upper arm is tightened, fluid gets trapped in the lower arm (forearms) and hands. Generally, I suggest arm elevation for two weeks after an arm lift or brachioplasty. During this time, your hands, forearms, and upper arms will be bandaged with an Ace bandage. The Ace bandage will also aid in eliminating fluid and swelling. Your elbows should be straight with your hands elevated above your heart. Your upper arm or elbows should be on one or two pillows. However, if there is still swelling two weeks after your arm lift or brachioplasty, you will need to continue arm elevation. Once the arm lift incision is completely healed, I would suggest arm compression garments for 6 to 8 weeks. This will also help to minimize fluid accumulation and also help to flatten the scar. If you have any other questions regarding the arm lift or brachioplasty, please contact my office. Sincerely, Dr. Katzen
