has part has part characteristic of has modifier Abnormal morphology of the nasal alae Underdeveloped nasal alae The alae nasi are the lateral portions of the nose or the wings of the nostrils, which partly encircle the nostrils (nares). They are usually about the width of the columella, but vary greatly depending on the shape of the nostril. Note that individuals may be described as having a Cleft ala nasi, but have a severely underdeveloped ala nasi. In an underdeveloped ala the continuity of the tissue encircling the nostril is undisturbed while in a cleft it is disrupted. With severe hypoplasia of the nasal alae, the nasal tip may appear depressed.
