First, is the prosthetic breast augmentation surgery painful? Intravenous anesthesia can be used in prosthetic breast augmentation surgery, which avoids the fear of patients under local anesthesia. Combined use of epidural anesthesia for analgesia is a well-known anesthesia method used in caesarean section, and the operation process is stable and safe. Even for people who are sensitive to pain, there will be no obvious pain after giving powerful painkillers. Second, is breast prosthesis harmful to human body? Medical silica gel is a kind of organic silicon compound polymer, which is non-toxic and harmless to human body and does not cause cancer. At present, it has been widely used in various medical fields, such as silicone valves in cardiac surgery, aqueducts in neurosurgery, artificial joints in orthopedics, catheters and so on. Moreover, the removal of the breast prosthesis is also thorough, which eliminates people's worries. Third, how to choose the size of breast prosthesis? Once the shape of the implant is decided, the next problem is to choose its size. The bigger a woman's breasts are, the more beautiful they are. This formula is perfect: standard bust = height x0.53, and the bigger the implant, the better. It will be limited by body size, existing skin elasticity and breast tissue volume. These factors will prevent the breasts from expanding to the size you want. The skin must be elastic enough to completely cover the implant during the operation. If the implant is too large for the volume of skin and corresponding tissues, it may leave adverse consequences that can be detected by naked eyes or touched under the skin, which will damage the effect you want to achieve. 4. Do you need hospitalization or rest for breast augmentation with prosthesis? It is best to stay in hospital 1~2 days after operation, and you can resume your daily work after one week. If you want to perfect your curve through breast augmentation surgery, you must find an experienced professional plastic surgeon and carefully design and operate according to everyone's needs in order to achieve satisfactory results.
