Saddle shape correction is the best way to improve saddle shape at present. There are two kinds of materials used in saddle nose correction: autologous tissue and substitute: autologous or allogeneic costal cartilage and ilium can be used as autologous tissue; Molded silicone rubber is usually used as a substitute. Mainly to restore the normal shape, the surgical steps are as follows: 1. Preparation before saddle nose correction: the size and shape of the implant should be estimated, and the wax pattern should be prepared in advance if necessary as a reference for trimming the implant during correction. 2. Incision: make a bird-shaped incision along the edge of the tip of the nose and the alar; In recent years, transverse incision of upper lip groove or medial incision of nasal cavity has also been adopted. 3. Stripping: cut the skin or mucosa and subcutaneous tissue, and then use thin scissors to make invisible separation to the root of the nose; The cavity formed after peeling is based on the correct placement of the implant, which is convenient for postoperative fixation and achieves the expected shape. If the level of stealth anatomy is under the periosteum, it is easier to fix the graft. Do not pierce the skin when peeling. 4. Implantation of filler: After the implant is properly trimmed, it is best to put it into the wound for fixation at one time. If there is any difference, measure the position and quantity of trimming, and trim it slightly after taking it out. 5. Suture and pressure dressing: tightly sew in situ, and put the rubber tube lined with oil gauze into the nostril; The back of the nose was bandaged and fixed with pressure. The saddle nose deformity has been corrected. That's the introduction of saddle correction. I believe you have got some idea through the above introduction.
