ello, Thank you for your question regarding whether developing a hole under your armpit after an arm lift is normal, how can you repair the problem and how did the hole occur? Thank you for your history and your pictures. First, developing a hole under your armpit after an arm lift is not normal. However, developing a hole is very common after an arm lift, especially in the axillae or armpit. There are many reasons for developing a hole in the armpit after an arm lift. The armpit has hair follicles, which harbor bacteria. Pre-operative shaving or armpit surgery can cause infections and skin breakdown, leading to a hole. Also, in the armpit region are lymphatic channels and nodes. These can become damaged are result in creating a hole. Also, you may have moved too much in the post-operative period, leading to the area opening. You may have rejected a suture in the area that may have come out already or may still be inside you. Also, the post-operative garments may have rubbed this area, leading to wound breakdown. As you can se, many causes can lead to a hole under your armpit after an arm lift. In the end, in your case, we may never know the real reason. Next, let’s analyze your pictures. You have a Class 1 wound that is irritated, but is not infected. Now, let’s discuss treatment. Most plastic surgeons would treat this area conservatively with topical antiseptics (such as Betadine) and antibiotic ointments (such as Bacitracin or Mupirocin). Another approach would be more aggressive. This would include a small surgical procedure. In the office, the armpit hole would be locally anesthetized. The hole would be surgically removed, and the defect would be closed with sutures on the outside. The sutures on the outside would minimize infection. Whether you proceed with the conservative or aggressive approach, this armpit hole will heal. It just depends on how you and your chosen armlet plastic surgeon want to proceed. Most plastic surgeons would not recommend applying deodorant. Good luck. I hope that I have answered your question regarding whether developing a hole under your armpit after an arm lift is normal, how can you repair the problem and how did the hole occur? Since an arm lift can be a challenging surgery, please seek an experienced, board-certified plastic surgeon with significant experience performing these types of lifts. Do your research. Make sure they have performed at least 150 arm lift procedures. Make sure they have the before-and-after pictures to prove it. Carefully examine their before-and-after photos and review their RealSelf profile.
