Hello, Thank you for reaching out with your concerns about the scars from your arm lift, arm reduction, or brachioplasty. After reviewing your history and pictures, it's essential to determine the nature of your scars. If they are raised, bumpy, and extend beyond the original wound boundaries, they are likely keloids. If they don't exceed the scar limits, they are probably hypertrophic scars. While keloids and hypertrophic scars differ slightly in their nature, the treatment for both is quite similar. There are various treatment options for both keloids and hypertrophic scars. These include injections of prednisone or 5-fluorouracil (5FU), microneedling, dermabrasion, laser treatments, radiation, and surgical excision. Since you are one year post-surgery, most plastic surgeons would suggest either fractional laser treatment or surgical excision as the most appropriate options. Fractional laser treatment works by disrupting the scar tissue and facilitating the formation of new, healthier skin. This process may require multiple sessions, typically around five or six, to achieve the desired results. On the other hand, surgical resection of the scar provides a more definitive solution. Both arms can be treated simultaneously or in stages. During the resection, the scarred area is numbed with local anesthesia, and the scar tissue is surgically removed. Given your history of scars widening, the use of permanent sutures might be recommended to ensure better healing. This procedure can be performed under either local or general anesthesia, depending on your preference. I hope this answers your question about managing hypertrophic or keloid scars following an arm lift, arm reduction, or brachioplasty. Wishing you the best of luck with your treatment. Sincerely, Dr. Katzen
