Prosthetic breast augmentation is to make an incision around the chest, then implant the carved breast prosthesis into it, and finally sew it up to achieve the effect. The prosthesis material is made of silica gel. Prosthetic breast augmentation has the advantages of strong adaptability, extensive materials, high safety, strong agreement, simple method, reliable effect, satisfying personality, good effect and good compatibility. Most people think that "beautiful breasts" have the following characteristics: the shape is tall and straight, plump and symmetrical, and it is hemispherical; The breast position is higher, between the second and sixth ribs, and the nipple is located between the fourth rib; The distance between the two nipples is more than 20cm, the diameter of the basal surface of the breast is10-12cm, and the axis of the breast (the height from the basal surface to the nipple) is 5-6cm. Breast augmentation surgery is basically designed with reference to this standard, but the effect will vary from hospital to doctor. According to clinical experience, capsule contracture can be avoided and the effect of breast augmentation with prosthesis can be ensured as long as the following factors are avoided: 1. Because the change of hematoma after prosthetic breast augmentation is an important cause of capsular contracture, cosmetic plastic surgeons must be very clear about anatomy and avoid excessive trauma and hematoma during prosthetic breast augmentation. Drainage must be sufficient after prosthetic breast augmentation surgery. 2. It is an important measure to prevent capsular contracture to fully peel off the cavity during breast augmentation with prosthesis. 3. Effective and accurate massage after breast augmentation. 4. Try to use rough prosthesis in breast augmentation surgery. 5. Strict disinfection and aseptic control in breast augmentation surgery. 6. According to the patient's detailed situation, the implantation site of breast augmentation prosthesis should be selected as far as possible under the pectoralis major muscle. 7. Prosthetic breast augmentation surgery absolutely avoids the presence of foreign bodies such as talcum powder, gauze and thread.
