The following are some of the possible situations that may occur during the surgery Please read carefully: 1. Incision scar: This surgery requires a skin incision, which will leave permanent traces later and may become more obvious due to scar growth. 2. 2. Residual gel of Omniderm (Ingel Farrer): Since the injected substance has no envelope and invades into the tissue, it is difficult to determine the injection level accurately, and the surgery definitely cannot remove the gel 100% completely. Such as (local redness, swelling, pain and itching, etc.) but generally this happens very rarely. 3. Post-operative breast shape change: Due to the removal of the gel and the removal of the mass, the breast may change in volume, size and shape, and there may be local depressions (especially in the left breast at the upper mass) or bilateral breast asymmetry. 4. Because of the large trauma to the breast and surrounding tissues, this surgery may affect the function of the breast and may damage the pectoralis major muscle. 5.The incision through the areola may affect the sensation of the nipple areola. (About 3 – 6 months can basically recover) 6, bleeding, formation of hematoma, infection 7, postoperative drainage (tube or piece) placed 1-2 days. 8, delayed healing of incision: incision tissue that is stuck with gel may lead to delayed healing of incision or even non-healing.
