Breast augmentation refers to the application of good quality and suitable size implants in suitable locations such as under the glands or under the pectoralis major muscle to increase the volume of the breast, improve the shape and symmetry of the breast and make it feel good. It is generally suitable for women who are thin and have insufficient fat content and have certain requirements for breast shape, the details of which should be evaluated after the doctor’s interview at the hospital. Although breast implants are convenient, beautiful and one-time, they also have certain disadvantages. Don’t think of implants as lifelong, aging may occur within a certain period of time and may involve the removal of the problem. The retention time varies due to various reasons, such as trauma, extrusion, and aging of the human body. Currently, statistically, good quality prosthesis can be maintained for at least 10-20 years. The specific retention time of its shape needs to be determined by changes in the shape of the breast, such as the supporting tissues, fat, skin, and the understanding of aesthetics of the breast will change over time, making the original better breast augmentation effect less desirable. In addition, after breast augmentation, it is recommended to review once a year (physical examination + ultrasound) and MRI examination if necessary. The FDA recommends MRI examination every 2 years after 3 years of surgery, and according to the domestic situation, it is recommended that MRI must be done once in 8-10 years, and every 2 years thereafter, so that problems can be detected in time and solved as early as possible. If there is contracture or deformation of the prosthesis, the prosthesis should be removed or replaced in a timely manner.
