Ear cartilage rhinoplasty is the transplantation of autologous cartilage tissue to the nose in order to elevate the external nose, and the donor cartilage is often taken from ear cartilage, nasal septum cartilage or rib cartilage. Ear cartilage rhinoplasty has the advantages of good tissue compatibility, solidity and no rejection reaction, but there are certain risks, as follows: 1, incision scar: after cutting the auricular cartilage, there may be an incision scar, and if there is hyperplasia, it can lead to unattractive, and it is generally recommended to cut the auricular cartilage behind the ear or in the groove of ear, so as to make the scar more invisible; 2, abnormalities of the nasal head or the cartilage is visible: the cartilage transplantation is generally The survival rate of cartilage transplantation is high, but due to individual differences, uneven survival of cartilage may occur, and the absorption of cartilage may lead to abnormalities or cartilage in the nose; 3. Nasal contracture, deformity, hardness: after reduction of the nose and implantation of ear cartilage, scar proliferation may lead to contracture, deformity, hardness; 4. Adhesion: uneven survival of cartilage may lead to adhesion; 5. Calcification: ear cartilage is an elastic cartilage, and it will be calcified and absorbed, but the degree of calcification will not be very large. Calcification: ear cartilage is an elastic cartilage, which will be calcified and absorbed, but the degree of calcification will not be very big; 6, other: ear cartilage may be exposed in the nose, and may be extruded with the bones of its own nasal columella, which will lead to the exposure of the incision of rhinoplasty or the situation of the nostrils not being rounded and smooth. After rhinoplasty with autologous ear cartilage, it is strictly forbidden to touch the surgical incision with hands, and avoid the incision getting wet, minimize the activities to prevent the position of the prosthesis from moving, and at the same time, it is necessary to prohibit spicy and stimulating food, smoking and alcohol, in order to facilitate the recovery.
