Breast pigmentation and loss of sensation in the lower portion of the breast are possible side effects following breast reduction surgery. Here's some information about these issues:1. Breast Pigmentation: Changes in pigmentation, including darkening or lightening of the skin, can occur after breast reduction surgery. This is typically due to the redistribution of tissue and changes in blood flow to the area. In some cases, pigmentation changes may resolve over time as the tissues heal and settle. However, in other cases, pigmentation changes may be permanent. It's essential to discuss any concerns about breast pigmentation with your plastic surgeon before undergoing surgery.2. Loss of Sensation: Loss of sensation, including numbness or decreased sensitivity, in the lower portion of the breast is a common side effect of breast reduction surgery. This occurs because the nerves in the breast tissue are unavoidably disrupted during the surgical process. Sensation may gradually return over time as the nerves regenerate, but it's not guaranteed. Some patients may experience permanent changes in sensation following breast reduction surgery.It's important to note that every individual's experience with breast reduction surgery is unique, and outcomes can vary. Factors such as the surgical technique used, the extent of tissue removal, and individual healing patterns can all influence the likelihood of experiencing pigmentation changes and sensory changes.If you have specific concerns about breast pigmentation or loss of sensation after breast reduction surgery, I recommend discussing them with your plastic surgeon. They can provide information and guidance based on your individual circumstances and help address any questions or uncertainties you may have. Additionally, they can offer recommendations for managing these side effects and optimizing your overall surgical outcome.
