Nasal exposure
People's nostrils can be exposed. Generally speaking, the exposed area should not exceed 1/3 of the actual nostril area, but be greater than 1/3. Nose size is mainly manifested in the following two aspects: 1, and the two nostrils are different in size and may be congenital. For example, patients with cleft lip and palate (commonly known as rabbit lips) are often accompanied by nostrils of different sizes. Acquired nostrils vary in size and can be caused by diseases, trauma, burns, scar contracture and other reasons. Correct the size of the nostrils. Large nostril plastic surgery needs to design a plan. 2, anterior nostril stenosis and atresia Nose stenosis and atresia not only affect breathing, smell and development, but also affect the development of the entire face. Besides congenital factors, nostril stenosis and hemispheric occlusion are mostly caused by acquired factors such as trauma, burn, scald or infection. Anterior nostril stenosis or occlusion, especially scar stenosis or occlusion, requires plastic surgery in appearance.
