The shape of the nose varies significantly with different races, and the different shapes of the nose are the result of the struggle between human beings and nature. In terms of biological evolution, the warmer the climate, the wider the nostrils and the shorter the bridge of the nose. For example, the nose of African blacks is wide and flat, just to breathe a lot of warm and humid tropical air. The colder the climate, the narrower the nostrils and the sharper the nose.
When studying a person's nose, what we observe is not an isolated nose, but from the forehead, eyebrows and eyebrow arch, through the midfacial structure, and then the nose, upper lip and mandible; And chin; Make an overall observation.
The contour of the external nose consists of curves in different light and different positions, which are not only needed by surgical artists when planning plastic surgery; It is also an important standard curve to evaluate the effect of plastic surgery. The interruption or deformation of these curves will lead to the change of nose shape. Only through surgery can the distorted curve of the external nose be restored to match the aesthetic curve below, and the appearance can be natural.
There is a big contrast before and after nasal plastic surgery, which requires the success of the operation and the good cooperation of postoperative nursing.
