Liu Hongwei, an expert in chest plastic surgery at the Health Management Center of Guangzhou Overseas Chinese Hospital, said that it usually takes 5-7 days to take stitches after the wound is healed. Silicone prosthesis plastic surgery incision: areola four-sided incision or nipple four-sided incision: the two are the same, but the scar is hidden around the areola or the junction between nipple and areola is different, but the disadvantage is that some mammary glands and more nerves need to be destroyed, and the possible infection rate is relatively increased. Four-sided navel incision: published in the United States more than ten years ago, but few users. The main reason is that the path from incision to breast is the longest, and there may be groove marks under the skin between navel and breast in thin patients. Tissue dissection is the most uncertain and destructive of all surgical methods, and it is impossible to determine whether the breast implant is above or below the pectoralis major, which requires long-term follow-up. Axillary incision is the most commonly used method, and the scar can be as small as two centimeters and hidden in the folds. Unless the physique is special and the scar is not obvious for a long time, it is the fastest method for experienced doctors, but the disadvantage is that the surgical stripping process is carried out blindly, the tissue damage is great and it is difficult to stop bleeding.
