Hello, and thank you for your question regarding your armpits not healing well after an arm lift. Incisions in the armpit are notorious for poor healing. Poor armpit healing is partially due to the anatomy of the armpit or axilla. The armpits contain sweat glands, hair follicles, and lymph nodes. Interruption or partial sweat gland removal can lead to poor healing and armpit infection. The armpit hair follicles can harbor bacteria in the hair shaft and cause infection. Removal or disruption of the lymphatic vessels can also cause poor wound healing. In addition, the medical-grade garment or ace wraps, used to keep bandages in place, can also rub against the armpit and cause wound breakdown. Additionally, the armpit is susceptible to wound breakdown because of the joint's mobility. You'll need to follow up with your plastic surgeon regarding their preferred method of wound closure. Because the armpit wounds are open, the open wounds should not be closed. If your armpit wounds we surgically closed, you might develop an infection, which could cause further opening of the armpit incision. Surgically closing the armpit could also cause slow healing. Typically, most armpit incisions are left to heal with a technique called healing by secondary intention. That means the depth of the wound heals first, and then the edges come together. Bacitracin or Venelex are good topical creams to accelerate healing. Alternatively, mupirocin can be used in patients who are highly susceptible to MRSA infections. If the wounds are deeper, they may require wet-to-dry dressings with normal saline or Dakin's solution. Supplemental modalities to accelerate wound healing include hyperbaric oxygen. Hyperbaric oxygen supplementation forces oxygen into the tissues and promotes wound healing. Regarding systemic products, most plastic surgeons would encourage extra vitamin C, zinc, and magnesium. These have been medically proven to accelerate wound healing. Most plastic surgeons suggest that you do not place silicone on open wounds. This will slow wound healing. Thank you for your question regarding your armpits not healing well after an arm lift. I hope I have answered your question regarding what to do about armpit openings and wounds after an arm lift. If you have any questions regarding the arm lift, arm reduction, or brachioplasty, please get in touch with an arm lift expert. Since a brachioplasty or arm lift surgery is difficult, 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 150 arm lifts. Make sure they have the before and after pictures to prove it. Please carefully look over their before and after pictures and check their reviews on RealSelf. Sincerely, Dr. Katzen.
