The specific which breast augmentation is good, according to the patient’s personal situation, especially the specific situation of bilateral breasts to choose, rather than blindly choose a way to adjust, there are mainly two clinical ways of implant filling and autologous granular fat injection, which can be selected under the guidance of doctors: 1. Implant filling: If the thickness of tissue under the skin of bilateral breasts is more than 2cm, and the applicant wants to have a more upright breast shape, silicone implants can be chosen for filling. Through the armpit, areola or submammary fold skin, choose one of them for the peeling of the cavity after the mammary gland or after the pectoralis major muscle, and place the silicone implant into the middle of the cavity, which can achieve immediate breast enlargement effect. However, since silicone implants are biological materials, some people have rejection or allergic reaction to this material, which may cause an increase in local exudate and contracture of the envelope; 2.Autologous granular fat injection: If the subcutaneous tissue of the breast is very little, accompanied by the phenomenon of sagging, the subcutaneous fat can be super-infused with local anesthetic in the parts where local fat accumulation is more obvious, such as the abdomen or thighs, buttocks, etc. The aspirated fat particles will be processed and filled into the subcutaneous, mammary glands and muscles of both breasts, so that the volume of both breasts can be increased, which can also achieve good breast augmentation effect. Autologous fat particles for breast augmentation may form nodules of different sizes under the skin or in the mammary glands, and if the nodules are large, they may need to be removed surgically again. Therefore, the clinical choice between breast augmentation with silicone implants or breast augmentation with autologous granular fat injection can be made according to the patient’s bilateral breast development conditions and the patient’s personal wishes. However, it should be noted that there may be complications after surgery, such as local bleeding, hematoma, skin petechiae, and also wound infection may occur, so you should follow the doctor’s instructions for regular review after surgery.
