Hello Loving802781, Thank you for your question regarding a 57 pound weight loss and is an arm lift the right procedure for bat wings? Thank you for your history and your pictures. First, we should analyze your pictures to determine the best procedures. According to your pictures, you have moderate cutis pleonasmus (excess skin) and moderate dermatocholosis (loose skin) with stretch marks (stria). Also, you have arm lipodystrophy (excess fat). Because of your excess skin, arm liposuction alone is not the best answer. Therefore, you need excision of arm skin. There are six types of arm lifts or brachioplasties: crescent or mini, modified longitudinal, T-incision, longitudinal with the scar in the bicipital groove (between the biceps and triceps in the inner arm) , longitudinal with the scar along the back of the arm (triceps), and complete upper and lower brachioplasty with an incision from the armpit to the lateral wrist. Most plastic surgeons would recommend a longitudinal with the scar in the bicipital groove with arm liposuction. Your arm reduction would take about 3 to 4 hours under general anesthesia. No drains are required. Plan on a 2 to 3 week recovery. You will need to wear your compression garments for about 6 weeks. I hope that I have answered your questions regarding the arm reduction, and specifically a 57 pound weight loss and is an arm lift the right procedure for bat wings? If you have any more questions regarding the arm lift, arm reduction, brachioplasty, arm scar revision, or arm crease fat grafting, contact an experienced plastic surgeon.
