Generally speaking, when a foreign body (such as a silicone prosthesis) enters the body, the immune cells in the body will recognize the foreign body, and then form a thin connective tissue membrane around the foreign body to separate the foreign body from the body tissue. This is a capsule.

After augmentation rhinoplasty with L-shaped silicone prosthesis, fibrous tissue capsule is formed on the surface, which is thickened and tightened continuously, and the pulling nose tip is shorter and shorter, that is, capsule contracture. If capsule spasm occurs, the prosthesis will be deformed and it is easy to appear celestial phenomena.

When this happens, costal cartilage is the first choice for repair.
