Nasal deformity may be either functional or cosmetic.
Functional describes nasal breathing blockages, snoring, decreased smell or taste, nose bleeds or chronic inflammation. A crooked septum (the middle section of the nose composed of cartilage and bone), scar tissue, collapse or weakening of structures in the nose. Cleft lip, cleft palate, nasal mass or anomaly are deformities present at birth and can be corrected by surgery. Nasal trauma may result in a fracture and deviation and change both the appearance and functioning of the nose. Some diseases can affect the appearance and function of the nose as well.
Cosmetic concern may involve patient perceptions about the symmetry, length and width or tip of the nose and may be changed through surgery.
