1. Infection: The main manifestations are redness, swelling, fever and pain, which can occur soon after operation or at any time after operation. Without systemic symptoms, subacute or chronic infection is difficult to diagnose; If the symptoms do not subside after proper treatment, it is recommended to take out the artificial breast in time.

2. Asymmetry or sagging: Asymmetry is caused by the following reasons: incorrect choice of prosthesis shape and size, capsular contracture, hematoma, prosthesis rupture, thoracic asymmetry and breast tissue asymmetry. In addition, after breast augmentation, breasts will droop over time like natural breasts.

3. Abnormal nipple and breast sensation: Breast augmentation through areola incision may cause local temporary or permanent paralysis or hypersensitivity of nipple or areola.

4, artificial breast rupture: artificial breast is lifelong unsustainable, and ruptured artificial breast usually needs to be removed and replaced. However, the hidden rupture of artificial breast is usually asymptomatic, and the causes of rupture include surgical instrument injury, intraoperative or postoperative trauma, excessive extrusion, excessive exercise, close contact with the body, aging of materials and so on. Therefore, it is best to have a regular physical examination so as to find problems early.

5. Capsule formation and contracture: The formation of capsule around the prosthesis after operation is the normal physiological response of the body to the implantation of foreign bodies in soft tissue. It exists in all patients to varying degrees, and it can be thin or thick, which varies from person to person. Capsule contracture will increase the difficulty of detecting breast cancer.

6. Prosthesis exposure: The improper size and position of the artificial breast and its mismatch with the cavity may lead to the displacement, torsion or exposure of the artificial breast after operation. If it is implanted in the wound site, the incidence of exposure will increase.

7, hematoma: careful hemostasis is the key to prevent postoperative hematoma, do not implant artificial breast when bleeding is not controlled. Huge hematoma, breast enlargement, tenderness, tissue discoloration, etc. If left untreated, it will lead to the later exposure of artificial breast and secondary capsular contracture.
