The nostril is the opening found on each side of the nose and that allows the entry and exit of air during breathing. The nostrils are surrounded by soft tissue and cartilage that form the structure of the nose and are separated by the nasal septum. The nares are important for respiratory function and can affect the quality of breathing if they are blocked or narrowed. In addition, the shape and size of the nostrils can affect the aesthetic appearance of the nose and the face in general. The correction of the nostrils may be necessary in the plastic surgery of the nose to improve cosmetic appearance and respiratory function. Common procedures that involve correction of the nostrils include rhinoplasty and septoplasty. It is important that the correction of the nostrils be performed by a Plastic Surgeon qualified and experienced to ensure safe and effective results.
