2. Three-stage prosthesis: the columella of nose is divided into two parts, plus the back of nose, * * * is three parts.
3. Two-stage prosthesis: the back of the prosthesis is hard (equivalent to the hard bone part of human nose), and the nose head and columella part of the prosthesis are soft (equivalent to the cartilage part of human nose), which is divided into two parts as a whole; But sometimes the tip of the nose is not delicate enough, blunt and unsatisfactory.
4. Three-stage prosthesis: the columella of nose is divided into two parts, plus the back of nose, * * * is three parts. Rhinoplasty prosthesis accurately depicts the complete nose shape, heightens the bridge of the nose, narrows the tip of the nose and raises the tip of the nose. Rhinoplasty prosthesis works fine. According to different parts of the bridge of the nose, rhinoplasty prosthesis materials with different softness are selected. The back of the nose is moderately soft and hard, the nose column is hard, and the tip of the nose is getting softer and softer, which is a line with the traditional characteristics of China.
5. Segmented prosthesis: The whole prosthesis is equivalent to nose, nose column and nose back, all of which are a whole. That is, L-shaped or willow-shaped rhinoplasty, but the effect of nasal tip is not good, and sometimes even infection or prosthesis wear.
