Even for the areolar incision, most of the operations are performed under blind vision because of the small incision, which increases the chance of vascular and nerve damage and blood loss, and the corresponding fibromuscular strips are not completely disconnected, thus affecting the smoothness of the lines around the breast. Using modern endoscopic technology, the blind surgical peeling technique is converted into a simultaneous visualization process, which not only reduces the trauma of breast augmentation surgery, but also significantly improves the accuracy and safety of the surgery, thus greatly increasing the degree of acceptance of the surgery by the candidates. The operation can be completed under stereoscopic visualization, the level is more precise and clear, the bleeding point is found in time to stop bleeding, the post-operative swelling and petechiae can be reduced, and the incidence of post-operative contracture of the pericardium can be reduced. The postoperative period is more comfortable and quicker to recover, feels natural, and does not affect fertility and breastfeeding. The separation under visualization can be done in two planes as needed to make the shape of the lower part of the breast more perfect. At the same time, the peel range can be accurately positioned and more in line with the preoperative design to ensure the symmetry and consistency of both sides of the breast augmentation form perfect. When separating to the lateral border of the sternum, meticulous separation and identification can effectively protect the skin penetration branch of the internal thoracic artery from being damaged, further improving the safety of the operation. The 4-5 intercostal nerves can also be avoided during the lateral separation to protect the nipple sensation. In the axillary incision, the placement of the teardrop-shaped prosthesis is difficult by feel alone, but it is easy to place the prosthesis in place by endoscopic observation. The reliability of the umbilical incision for breast augmentation can also be significantly improved with the aid of an endoscope.
