Beauty is the pursuit of all women. It is widely recognized that one of the important standards of female beauty is to have full, proportionate and elastic breasts. However, due to congenital or acquired reasons, not all women are able to have the ideal breasts, which often causes inconvenience and even great mental pain. Fortunately, all of this is not irreparable, and modern plastic surgery has made it possible to treat all types of breast deformities significantly and effectively. A moderately full breast is a symbol of femininity. Most of the causes of microtia in women are due to congenital dysplasia, and a few are also seen as atrophy after breastfeeding, etc. Breast augmentation is a safe and convenient procedure, which simply involves placing artificial material under the breast or pectoralis major muscle to augment the breast. The surgery requires a small incision 3-5 cm long in the axillary crease, areola or inframammary fold, which is very concealed after healing. There are two main types of breast implants in common use: silicone gel implants and saline-filled implants. The former has a better feel and appearance, but is slightly more difficult to place, and the adverse effects of silicone gel on the human body have not been confirmed, but are still debated; the latter is easier to place and remove, and is safer. It is worth mentioning that there is now a method of breast augmentation through liquid silicone rubber injection, although it seems faster and less traumatic, but once the complications arise, the consequences are serious, so it is not worth advocating.

Breast enlargement is often accompanied by breast sagging in varying degrees. Severe hypertrophy and sagging of the breasts can cause hunchback, eczema of the skin under the breast, etc. Depending on the cause, it can be classified as hyperplastic, obese and youthful hypertrophy; and depending on the degree of hypertrophy and sagging, it can be classified as mild, moderate or severe. The purpose of plastic surgery is to restore the normal and moderate volume and shape of the breast. The specific steps include removing the enlarged and loose skin, removing the overgrown breast tissue, and lifting the nipple areola to its normal position while preserving the lactation function of the breast as much as possible. There are various methods of surgery, the more common ones being the vertical double-tip method and the horizontal double-tip method. The breast is considered to be the second female sex characteristic. The absence of a breast due to a tumor or trauma can be excruciatingly painful. This emotional trauma can be remedied by breast reconstruction. Reconstruction after mastectomy for breast cancer can be done immediately or after the end of radiation or chemotherapy. If a modified radical surgery is performed, in which the pectoralis major muscle and a moderate amount of skin are preserved, immediate expander plus breast prosthesis reconstruction can be performed. After a few months of treatment, including skin expansion, implant placement, and areola nipple reconstruction, the procedure is completed. If a standard radical surgery is performed, breast reconstruction can also be performed using a latissimus dorsi muscle flap or a rectus abdominis muscle flap, both of which can achieve satisfactory results. There are many other types of breast reconstruction, and the methods are constantly evolving and improving. At the same time, each person’s cultural background and their own requirements are different, so in order to achieve the most satisfactory results, a professional place with a skilled physician is a wise choice.
