The supporting structure of the nose consists of nasal bone and nasal cartilage. Among them, there are two nasal bones, and the nasal cartilage includes two lateral nasal cartilages, two alar cartilages, a nasal septum cartilages and some smaller accessory cartilages. The integrity of these structures is the basis of maintaining the shape of the nose. Through the skin of the nose, we can observe the outline of these structures.

Nasal bone is two rectangular bone plates, thick on the top and thin on the bottom, narrow on the top and wide on the bottom. The upper end of nasal bone is tight and the lower end is slightly separated, and the combination line coincides with the median sagittal line. The nasal bone is connected with the nasal tip of the frontal bone upward, the frontal process of the maxilla on both sides, and the lower end of the nasal bone is connected with the lateral nasal cartilage horizontally downward at the lower edge of the orbit. Viewed from the side, the nasal bone is slightly concave backward from the anatomical nasal root point, and then walks down and forward at the most concave part of the nasal root, and the midline is connected with the cartilage of the nasal septum. It can be seen that the skeleton of the nose is actually composed of the nose bone, the frontal process of the maxilla and the nose of the frontal bone. The surface morphology of the frontal bone nose is as follows: the eyebrow arches on both sides naturally extend to the frontal nasal spine, and the eyebrow arches are prominent, and the frontal bone in the center of the eyebrow arch is relatively depressed, showing a "V" shape with a wide opening; The frontal process of maxilla is supported on both sides of nasal bone and connected with lateral nasal cartilage below nasal bone.
