Introduction
Under normal circumstances, possible complications of breast augmentation may include implant capsule contracture, fat liquefaction and nodules, infection, abnormal breast shape, and sensory abnormalities. Complications are closely related to the surgical technique, procedural standards, and individual physical condition. It is recommended to choose a qualified medical institution and an experienced professional surgeon to reduce risks. A thorough preoperative assessment of one's health status and an understanding of potential complications are also advised.

Generally, possible complications of breast augmentation may include implant capsule contracture, fat liquefaction and nodules, infection, abnormal breast shape, and sensory abnormalities. A detailed analysis is as follows:

1. Capsular Contracture

After breast implant surgery, the body may generate a foreign body reaction, forming a fibrous capsule around the implant. If this capsule thickens and contracts, it can cause breast hardening, deformation, and even swelling and pain. In severe cases, surgical removal of the capsule or replacement of the implant may be required.

2. Fat Liquefaction and Nodule Formation

In autologous fat breast augmentation, if the transplanted fat does not survive well, liquefaction and necrosis may occur, forming hard nodules. Some nodules may persist long-term and may need to be differentiated from tumors; surgical removal may be necessary in some cases.

3. Infection

If sterilization is inadequate during surgery or injection procedures, local infection may occur, manifesting as breast redness, swelling, fever, and pain. Severe infections may lead to abscess formation, requiring antibiotic treatment or even implant removal and abscess drainage. Recurrent infections may leave scars.

4. Abnormal Breast Shape

Implant displacement, asymmetry in size, or uneven injection of autologous fat may lead to breast asymmetry, uneven positioning, or unnatural appearance, affecting aesthetics. In some cases, secondary surgery may be required for correction.

5. Sensory Abnormalities

Surgery may injure nerves around the breast, leading to numbness, tingling, or hypersensitivity of the nipple, areola, or breast skin. Most cases gradually recover, but some individuals may experience long-term sensory disturbances, affecting quality of life.

The complications of breast augmentation are closely related to the surgical method, procedural standards, and individual physical conditions. Choosing a reputable medical facility and experienced surgeon can help reduce risks. A thorough preoperative assessment of one's health status and understanding of potential complications are recommended. Postoperative care instructions should be followed carefully, and any abnormalities should be addressed by seeking timely medical attention.
