Many people think that the nose bone needs grinding if it is too wide. In fact, this method can't improve this problem very well. Because the nasal bone is thin, even if it is filed off, the amount of removal will be small, so its width will not be reduced. In this case, it is necessary to artificially break the nasal bone and then pile it inside to narrow it. Because nasal bone plastic surgery does not use prosthesis, there will be no foreign body sensation and unnatural phenomenon, which can be said to be a good method. The method of narrowing the nasal bone: narrowing the nasal bone, osteotomy from the paranasal line: separating the nasal bone from the nasal septum on both sides, usually doing osteotomy twice on both sides of the nasal septum. These two incisions are not in the midline, so they are called paramidline. The midline osteotomy is commonly used, that is, the nasal bone is separated at the internal seam. Paramidline osteotomy usually has two surgical methods, through mucosa or from above. When there is no nasal septum operation, that is, when the nasal septum is normal or it is dangerous to open the nasal septum, paranasal osteotomy is performed through the nasal vestibular mucosa. Another method is to separate the nasal bone from the above through an intercohondral incision. Both methods were performed along the subperiosteal incision of the nasal cone. Surgical features: this type of nose can only be improved by simple rhinoplasty, but if the width of the nose root is changed, the nose will look big and stupid. By improving the inclination of the nasal bone, narrowing the nasal bone can not only improve the height of the bridge of the nose, but also narrow the back of the nose, tighten the alar and make the nose beautiful, which can be described as killing two birds with one stone.
