2. Separate the skin and subcutaneous tissue near the cartilage, and separate the nasal periosteum near the superficial surface of the nasal bone. All the way to the base of the nose You can also cut the periosteum with a scalpel and then separate it. 3. Nasal septum plasty (1) submucosal resection can be used for simple cartilage deviation. Make an imaginary line (called a safety line) from the lower edge of the nasal bone to the nose, and then you can remove the bone and cartilage without saddle nose due to excessive resection; (2) In recent years, it is generally believed that the less cartilage excision, the better the surgical effect. Therefore, we only cut the cartilage in the shape of "mouth" and "field" in the curved part, without separating the opposite mucoperiosteum, separating the mucoperiosteum of a nasal septum, and retaining the cartilage of the nasal septum, which is pushed by the convex side. Straighten the nasal septum (3) According to the deviation of the bridge of the nose, in some cases, it is necessary to loosen the bone continuity around the nasal septum and the bridge of the nose, only separate and cut off, and try not to cut off the cartilage. The main supporting force of the lower part of the bridge of the nose is the cartilage of nasal septum. There are two fixed points at the lower part of the bridge of the nose. The upper fixed point is at the joint of the upper part and the nasal bone, the lower fixed point is at the vomerosal bone and the nasal spine, and the lower edge of the nasal septum is attached to the vomerosal groove, which is a weak point, so that the lower part of the nasal septum is easy to shift and fall off to the L side. Especially congenital crooked nose. Therefore, many people adopt the "swingingd00roperation" proposed by Metzenbaun, that is, free the mucoperiosteum of the vomer, cut off the cartilage from the vomer, remove the fibrous tissue in the vomer groove, and cut off the uneven cartilage, so that the 65,438+0 cartilage flap with one mucoperiosteum turns to the center. Cartilage is reset in the vomeroid groove. If the vomeroid is skewed, it is called "turnstile operation". It should be cut at the joint of nasal base and moved to the midline. Incision connection with lateral nasal cartilage, vertical plate of ethmoid bone and nasal bone; Cut off the sharp rectangular protrusion and the vertical plate that breaks the ethmoid bone, so that the downward skew can be corrected. If the lower edge of the nasal septum cartilage is too long, it needs to be trimmed to make the nasal septum cartilage just reset on the vomerosal groove. In order to prevent dislocation again, a hole can be drilled on the plough bone, the lower end of cartilage can be sutured and fixed with stainless steel wire or nylon wire. (4) In some cases, after exposing the cartilage cone, the dorsal cartilage of the nasal septum should be cut from the dorsal edge of the nasal septum to separate the mucoperiosteum and the calling membrane on both sides. Then cut off the connection with the vertical plate of ethmoid bone and vomer (but keep the connection at the angle of ethmoid vomer), so that the cartilage of nasal septum is semi-free. Then, according to the bending degree of the nasal septum, a cartilage plate relaxation incision or a small part of cartilage wedge resection is made on the corresponding two sides to correct the cartilage of the nasal septum. The crooked nose is mainly manifested in the bridge of the nose below the junction of the nasal bone and the lateral nasal cartilage, and the width of the nasal cartilage on both sides is different. Therefore, one nasal cartilage can be cut off on the wide side to make the width of the two nasal cartilage equal, and then sutured with silk thread.
