The nostril is a rare disease, the nostril from the histology is the whole nostril, the nose back to the pharynx, to the larynx, down the channel process there are two holes corresponding to the anterior nostril called the posterior nostril, so the anterior nostril, if large, generally does not affect breathing, does not affect the other physiological functions of the nasal cavity, can not do special treatment. The nostril is formed by the two sides of the nose, and the nasal column, which is the structure separating the two nostrils in the middle, and the upper lip around the phase. If it is necessary for plastic surgery or trauma that causes some scars, you can have the anterior nostril reduction surgery. The surgery is actually very simple, as long as a part of the anterior nostril is removed and sutured, and the left and right sides are symmetrical. But if for some special aesthetic requirements, to carry out the relevant aesthetic measurement, plastic surgery requires special treatment, so do more delicate.
