Breast augmentation surgery with silicone implants remains the most common and effective solution for patients with small breasts. When choosing silicone implants for placement, many patients are confused by the various shapes of implants available; not only that, but some doctors’ opinions are also specious. Some patients just say in general terms that I want to raise my breasts from an A cup to a C cup. The cup is the standard when choosing underwear, A cup and C cup each in the end how much ml who can not say. Doctors are trying to save time by applying 220 ml of medium-surge hairy surface implants, resulting in some underfilling and some overfilling, and patients are still dissatisfied with the second surgery to replace the implants. How to choose a more scientific prosthesis? 1, combined with the patient’s own conditions, that is, personalized. Personalization is not only height and weight, but also includes the width of the chest, which is an important indicator of the diameter of the breast base. If the diameter is very large and the implant is small, it will not fill; on the contrary, the diameter is very small and the implant is too large, the implant will form folds in the cavity. Too large prosthesis will make the surface of the tissue thinning, and long to form a thick hard film, the prosthesis exposed, the shape is not good. 2, the elasticity of the breast skin. Breast skin loose can be placed a larger prosthesis, and vice versa, the placement of large prosthesis will make the skin over-stretching pain, and in the long run skin thinning, prosthesis sagging. Pre-operative examination can be forward traction nipple, you can also measure the maximum extension distance from the nipple to the lower wrinkle wall. 3, breast prosthesis surface soft tissue thickness. Use a clip to pinch the soft tissue, if the measured tissue thickness is less than 2cm, you can place a teardrop-shaped prosthesis to make the post-operative breast shape more natural. Too thin soft tissue coverage will be visible or palpable after surgery to the outline of the implant, to improve this symptom after breast augmentation can also be filled with autologous fat on the surface of the implant. Breast prosthesis surface soft tissue thick, placed round prosthesis and teardrop type prosthesis postoperative effect are similar, there is no need to spend a lot of money to place the teardrop prosthesis. 4, how to choose the degree of protrusion of the prosthesis. Generally want to increase the protrusion of the prosthesis to make the chest high idea most of the end in failure. Because too large protrusion will cause the soft tissue in front of the prosthesis thinning, the rear of the chest concave, long-term look not only will reduce the protrusion, the prosthesis outline is also easy to show. High protrusion prosthesis is used for breast breastfeeding after glandular atrophy, mild sagging of the breast patients. 5, glossy or hairy surface is good. Smooth prosthesis is soft and easier to place, but after placement the prosthesis can be rotated in the envelope, easy to form the envelope, need to massage; hairy surface prosthesis is the opposite, slightly hard, not easy to form the envelope, do not need to massage, slightly laborious to place. Prosthesis selection is complicated, but mastering the above points will be easy to see the day.
