Thank you for your question regarding the fact that you are five weeks after your brachioplasty and still unable to lift your arms over your head. This is not normal. However, you are still healing. It takes six to eight weeks to heal form a brachioplasty fully. Even then, some patients are not entirely healed. Since you lack the range of motion, you need to stretch this area. Once you are given clearance from your plastic surgeon, II aggressively stretches this area. I would wait til you're well healed. This can take 6-8 weeks after a brachioplasty. The best exercise would be to extend your arms over your head. Then grab your wrists. Then pull your wrists and slide your elbow behind your head. Flex from side to side at your waist. You should feel a pull in your armpit. You are pulling and stretching the good scar tissue. This is what you need. It would be best if you were very aggressive with this motion. Other exercises that can help include hanging from a pull-up bar, putting your arm over a chair, and holding a gallon of milk for an extended period. If these conservative measures do not work, you may need a physical or occupational therapist. These professionals can help with a range of exercises. If all else fails you may need either an injection of steroids or possibly even revision surgery. However, revision surgery is exceedingly rare. For now, I would focus on aggressive range of motion exercises at home and consider a physical therapist. I specialize in arm lifts. I hope that I have answered your questions regarding the arm reduction. If you have any more questions regarding the arm lift, arm reduction, brachioplasty or arm crease fat grafting, please contact my office. Since a brachioplasty or arm lift surgery is a difficult procedure, please seek an experienced, board certified plastic surgeon with significant experience performing these types of arm lifts. Do your research. Make sure your chosen plastic surgeon has performed at least 100 arm lifts. 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. Sincerely, Dr. Katzen.
