The patient’s grandmother told me not to let her niece be unable to lift her hand after the operation, because her niece is an art teacher and needs to lift her hand to draw on the blackboard every day. The post-operative recovery is still satisfactory! So why did this art teacher’s grandmother have such a concern? One of the core concerns of many young patients now is whether there will be scars under the armpits after surgery, and whether they will spend money to cure the armpit odor but leave two permanent earthworm-like scars? In fact, this is only one of them, only in some patients with obvious scars will occur, the clinical more patients show not the thick and dark scars raised in the skin, but the contracture of the scar in the subcutaneous tissue leads to flap folds, serious will produce a significant hanging feeling. Some patients cannot lift their upper limbs after surgery, and have severe pain after lifting to a certain angle; some thin patients will tell you that “I can see a tendon being pulled up in the armpit and the inner side of the upper arm”, but after examination, I found that it is a tendon stretched by the scar in the armpit; some other patients have the skin in the armpit area wrinkled up in layers after surgery These are all caused by the scars under the flap and are much more likely to occur than the surface scars. So how can this be avoided? This involves a lot of surgical details, including the thickness of the flap trimming, the flatness of the fat level (muscle surface) below the flap trimming, the tightness around the flap, the presence of blood and fluid under the flap after surgery, the evenness of the pressure bandage, etc. These skills are in the hands of your surgeon, and all you can do is to cooperate with your surgeon to do a good job in the post-operative restorative function exercise. I once met a timid girl, more than a month after the incision, because of fear and afraid to move the upper extremities, afraid of “incision cracking”, and her surgeon did not guide her functional exercise, resulting in serious scar pulling under the armpit. In summary, the prevention and remedy of axillary scar growth after axillary odor surgery is a discipline, especially the prevention of scars under the flap, which requires considerable attention from surgeons and patients!
