Breast augmentation is a common procedure in plastic and cosmetic surgery, and silicone gel implant breast augmentation is predominant in breast augmentation. 1.What is an implantable breast prosthesis? Breast implant is a kind of synthetic tissue substitute that is surgically implanted into the chest body to achieve breast enlargement and shape improvement, mostly in the form of a capsule, consisting of capsule wall (all of which are elastomer silicone rubber) and the content injected inside the capsule. 2.What are the types of breast implants? According to the content of the prosthesis, can be divided into silicone gel, saline, PVP hydrogel, vegetable oil and other types. According to the shape of the prosthesis, it can be divided into disc shape, anatomical shape; the same volume of the prosthesis can be divided into high convex, medium convex, low type. According to the structure of prosthesis, it can be divided into single capsule type, double capsule type and so on. With the advancement of materials and technology, silicone gel breast implants are almost exclusively used nowadays and there is enough evidence to prove their safety. Hydrogel and vegetable oil types have been eliminated, and saline-filled implants are rarely used because of gradual leakage and poor feel. 3.Where are the surgical incisions for breast implant placement? Armpit, areola, inframammary fold. The inframammary fold is rarely used because it is easy to expose scarring. The incision in the armpit is the most hidden. 4.Where are breast implants usually implanted? Breast implants can be implanted behind the pectoralis major muscle, behind the breast tissue, or bi-planar. What is biplane? It means that most of the implant is behind the pectoralis major muscle and the protruding part is behind the mammary gland, so that the edge of the implant can be covered by the pectoralis major muscle, and at the same time, it can have a perfect shape. The bi-plane method needs to be supported by endoscopic equipment hardware. 5.How to choose the size and shape of breast implant? The patient’s physical condition and the patient’s aesthetic point of view and requirements are the basis for choosing the size and shape of the breast implant. Full communication with the surgeon before surgery is crucial. The patient’s requirements are the main basis but should not exceed their own physical conditions. 6.Is the effect of breast implant lifelong? The current implants, especially the high-grade implants, have no life limit. However, the effect of breast augmentation is not lifelong, it will change with the patient’s body type. For example, if the implant is implanted before pregnancy, the breasts will change drastically after giving birth and breastfeeding, and the effect of breast augmentation will also change. 7.Is breast augmentation surgery more painful? Yes, it is. Therefore, it is best to use general anesthesia and add analgesic pump after surgery. It is not recommended to perform this surgery under local anesthesia, as the pain is relatively strong. 8.Do I need to massage the silicone gel implant after surgery? There are glossy and hairy prosthesis. Glossy prosthesis is easy to cause periosteal contracture, only Korea is still using it. Nowadays, most of the prosthesis used is hairy face prosthesis, which greatly reduces the incidence of contracture. Gross-surface implants not only do not need to be massaged, it can be said that massage should be prohibited. 9.How long does it take to recover after breast implant surgery? Generally one week after surgery to remove the stitches, does not affect daily activities, such as driving a car. However, it is forbidden to lift the upper limbs and support the upper limbs with force within one month. By two months, you can resume any sports.
