Breast reduction surgery is used for patients with breast enlargement to reduce breast volume, reduce breast weight, reshape the appearance of the breast and restore the patient’s physical and mental health. The operation is relatively simple, with the operating surface within the breast and at the soft tissue level, and does not interfere too much with human function, but it is more traumatic for the breast. However, clinically, breast reduction surgery will also have certain surgical risks, the corresponding surgical risks are as follows: 1. After breast reduction surgery, some patients will have blisters, hematoma, infection, etc. Some patients will also have nipple sensory loss, and even complete necrosis of the nipple and areola. In case of nipple and areola necrosis, the patient can be given a skin graft for repair. Therefore, in clinical breast reduction surgery, physicians should pay attention to the operation to reduce the risk of necrosis after surgery; 2. Once this occurs, debridement treatment can be taken to remove the granulation tissue, followed by flap repair. However, it should be emphasized that possible complications should be actively prevented after surgery, and these conditions should be dealt with in a timely manner to avoid affecting recovery.
