The rounded breast curve reflects the beauty of female form, and the plump 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. 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. Women with undeveloped or underdeveloped mammary glands, low and flat chest area, and lacking the characteristics of women with wide chest can consider breast augmentation, i.e., by placing breast implants to expand the volume of the breasts, make the shape full and proportional, improve the female body shape, and shape and restore the unique curve beauty of women. Breast augmentation is now one of the most common procedures performed in plastic and cosmetic surgery. Since the 1980s, Watanabe first proposed “subpectoral breast augmentation”, and this procedure has been widely used. However, in the axillary approach, the posterior cavity of the pectoralis major muscle is usually stripped under blind vision, so there is a lack of precision in the stripping. With the rapid development of modern technology, the birth of the latest endoscopic surgical assistance technology, its application in plastic surgery, regarded as microvascular anastomosis, craniofacial surgery, tissue expansion and other technologies, known as another milestone in the development of plastic surgery. 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 cutting-edge display technology, the whole process of axillary approach breast augmentation can be visualized, accurate separation and hemostasis can be performed, avoiding the blindness of the 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 the operation and thus obtaining a better aesthetic effect. This improves the precision of the surgery and leads to better aesthetic results. Breast augmentation with endoscopic surgical assistance technology converts the blind surgical peeling technology into a synchronous visualization process, which makes the range of peeling cavity more appropriate, the level more precise and clear, and the surgical operation can be completed under three-dimensional visualization, which reduces the surgical trauma, is safer, has a more comfortable recovery after surgery, feels natural, does not affect fertility and breastfeeding, and has no scar in the breast area, which truly meets the requirements of minimally invasive, and is another contemporary medical and It is another crystallization of contemporary medicine and modern technology, which further improves patient satisfaction. At the same time, the endoscopic technology further improves the effect of the umbilical incision approach for breast augmentation, and this incision is suitable for saline refillable breast implants. Endoscopic-assisted breast augmentation requires expensive endoscopic equipment and instruments, which will increase part of the cost accordingly, and it needs to be operated by an experienced professional plastic surgeon familiar with breast endoscopic techniques. However, the application of modern technology has reduced the trauma of surgery, improved the precision of surgery, and facilitated the creation of a more perfect breast shape, which is worth adopting.
