Putting ear cartilage on the tip of the nose is to prevent the silicone prosthesis from toppling out. If the silicone prosthesis is placed without ear cartilage, because of excessive tension, the silicone prosthesis in the nasal head area will have contracture of the peritoneum, and the tip of the nose can be toppled out of the nose with the contracture force increasing gradually, and putting the ear cartilage can prevent toppling out. Under normal circumstances, if there is no infection or the tension is not big, it will not come out. If there is inflammation, redness, swelling, and tissue infection in the nose, the silicone gel prosthesis will come out from the infected place after the ear cartilage is absorbed, and the redness of the nose can appear when the tension is particularly high.
