With the progress of society and the updating of people’s mindset and the continuous improvement of cosmetic technology, breast augmentation surgery is more and more accepted by women who love beauty. The rounded breast curve reflects the beauty of female form, and the full and proportional breasts with undulating peaks show the unique feminine body shape and beautiful curves, so women attach great importance to the shape of their breasts. Women with undeveloped or underdeveloped mammary glands, low and flat chest area, and lack of broad chest features can consider breast augmentation, that is, by placing breast implants to expand the volume of the breast, the shape of the full and proportionate, improve the female body shape, and shape the restoration of the unique curves of female beauty. At present, the most common method of breast augmentation is via pectoralis major muscle augmentation, and the latest technique is to do biplanar breast augmentation, however, the axillary approach, the posterior cavity of pectoralis major muscle is usually stripped under blind vision, so there is a lack in the accuracy of stripping. With the rapid development of modern technology, the latest endoscopic surgical assist technique has been born. The endoscopic instrument configuration mainly includes: imaging system, optical fiber, endoscope with different diameters and perspectives, and corresponding operating instruments. With the use of endoscopic display technology, the whole process of axillary approach breast augmentation can be visualized, the separation and hemostasis can be accurately performed, avoiding the blindness of operation, forming a thoroughly separated placement cavity and a better lower crease shape, which is more conducive to shaping and preventing the malposition and upward movement of breast implants, while avoiding damage to the sensory nerves that govern the nipple and areola, improving the precision of surgery and thus obtaining a better aesthetic effect. This improves the precision of the procedure, resulting in better aesthetic results. However, the implantation of breast implants will test the surgeon’s skills and experience because traditional breast augmentation surgery cannot see the situation inside the incision more clearly and comprehensively, especially the location of some blood vessels and breast tissue, which almost always depends on the surgeon’s experience to judge the operation, using endoscopic surgery-assisted technology for breast augmentation, which converts blind surgery The use of endoscopic surgery assisted technology converts the blind surgical stripping technique into a simultaneous visualization process, which makes the stripping cavity range more appropriate, the level more precise and clear, the surgical operation can be completed under stereoscopic visualization, which reduces the surgical trauma, is safer, the postoperative recovery is more comfortable and faster, feels natural, does not affect fertility and breastfeeding, no scar in the breast area, truly achieves the minimally invasive requirements, which is another crystallization of contemporary medicine and modern technology, and further improves the patient’s satisfaction. . Endoscopic-assisted breast augmentation requires expensive endoscopic equipment and instruments, which will increase the cost accordingly, and requires an experienced professional plastic surgeon familiar with breast endoscopic technology to operate. However, the application of modern technology has reduced the trauma of surgery, improved the precision of surgery and facilitated the shaping of a more perfect breast shape, which is a very good method.
