There are three main types of implants for rhinoplasty: i. Autologous rib cartilage, which can be taken in its own part, trimmed into the appropriate shape and placed in the nose. The advantage of autologous rib cartilage is that it is its own tissue and will not produce rejection, the disadvantage is that it requires a second surgery, increasing the recovery time and the risk of infection. Hyaluronic acid, hyaluronic acid is divided into small molecule, medium molecule and large molecule, large molecule hyaluronic acid has the best stability, it can be injected into the nose, the advantage is convenient and easy, the disadvantage is that the injection may be consumed, it needs 2-3 times of injection. Third, medical prosthesis, medical prosthesis is polymeric material, can be placed into the nose to modify the corresponding shape, the advantage is simple and easy to do, without secondary surgery, the disadvantage is that there is a possibility of rejection with the tissue, resulting in rhinoplasty failure.
