Frontonasal dysplasia, also known as median cleft face syndrome, is a very rare disorder characterized by abnormalities affecting the head and facial (craniofacial) region. Major physical characteristics may include widely spaced eyes (ocular hypertelorism); a flat broad nose; and/or a vertical groove down the middle of the face. The depth and width of the vertical groove may vary greatly. In some cases, the tip of the nose may be missing; in more severe cases, the nose may separate vertically into two parts. In addition, an abnormal skin-covered gap in the front of the head (anterior cranium occultum) may also be present in some cases. The exact cause of frontonasal dysplasia is not known. Most cases occur randomly, for no apparent reason (sporadically). However, some cases are thought to run in families.
