Saddle rhinoplasty

Generally, the saddle nose is more severe, and there are many defects in the bone or cartilage of the nose. Saddle rhinoplasty precautions: 1. In the past, intranasal incisions were mostly used to cut the skin between the side septum and the nasal column, and then enter the subcutaneous tissue of the back of the nose. However, in addition to the intranasal incision, there is one less surgical scar on the outside of the nose. There are few other advantages when the tip of the nose cannot be raised. The incision on the bottom of the nose is actually not significant. In terms of disinfection or surgery, It is superior, especially for installing "l" shaped models. There are two commonly used extranasal incisions. One is to make a straight incision along the nasal column from the tip of the nose; the other is to make a "t" incision along the front edge of the nostril. It can be used as needed in actual operation. 2. Use small scissors to reach the back of the nose from the incision and cut while peeling to separate the adhesion between the nasal bone and the subcutaneous tissue on the back of the nose. From the upper eyebrow to the maxillary bone on the outer side of the nose, the nasal bone and the subcutaneous tissue must be completely relaxed. 3. If it is a fusiform model, you can put it in and observe the correction of the nose shape. First of all, you should pay attention to whether the base of the model and the depression of the saddle nose bone are suitable. . If the substrate is not suitable, the model is likely to be distorted and deformed. If it is too large or the substrate is not suitable, it can be modified appropriately; if it is too small, it can be replaced by a larger model. 4. If the "l" model is used, it should be separated in the middle of the septum column to the bottom of the nasal column, and straight down to the maxillary nasal spine. If the transplantation model is autologous cartilage, the septal mucosa should be separated and then placed in the model. If it is a soft plastic model, you can fold it down and put it in. The pillar of the nasal column can also be folded up and put into the nose and then released. Note that although the model has a pillar in the nasal column, the tip of the nose of the model should not be lifted when the tip of the nose is pressed, but the tension should not be too large, otherwise it may hinder the blood supply of the skin on the back of the nose and cause the model to wear out. Especially plastic models are more likely to cause surgical failure. Therefore, if the tension is too large, you can take out the model and trim it down until there is no tension at all and it is more suitable. 5. If the correction of the nose shape is satisfactory, the incision skin can be sutured with silk thread. Cover the back of the nose with a little gauze. Use the back of the nose (can be made of dental proofing glue or aluminum sheet) and tape to fix the shape of the nose.
