Three or four thousand. In rhinoplasty with prosthesis, according to the different materials of nasal prosthesis, the cost of silicone rhinoplasty is about 2000-5000 yuan, and that of augmentation with expander is 8000-20000 yuan. If you do total rhinoplasty or autologous cartilage rhinoplasty, the cost will be higher. In addition, prosthetic rhinoplasty will increase the chance of nasal infection. I suggest you do autologous rhinoplasty.
