Different ethnic groups have different nose features, which are adapted to their facial features. As the name implies, the nose facing the sky means that the nostrils are upward, the nostrils are much exposed, and the bridge of the nose is short. Nose facing the sky is a unique nasal deformity in Asia, which is mainly the result of poor development of nasal bone and cartilage. On the surface, you can see that the whole nostril is always short of nose length; On the side, the nose and lip angle are too big. Xiamen Meilai experts said that the shape and size of nostrils are surrounded by alar, columella and root of nose, which is related to the length of these three structures and the radian of alar. There are often three deformities in the nose: nostril, nose head and nose columella. Because nasal surgery requires high skills from doctors, the risk of choosing a local formal medical plastic surgery institution is relatively small.
