Craniometaphyseal dysplasia is an extremely rare genetic disorder characterized by distinctive abnormalities of the head and facial (craniofacial) area, impairment of certain nerves (cranial nerves) that emerge from the brain, and malformations of the long bones of the arms and legs. In infants and children with craniometaphyseal dysplasia, there may be overgrowth and/or abnormal hardening of certain bones of the skull (cranial hyperostosis and/or sclerosis) and overgrowth (hypertrophy) of craniofacial bones, resulting in widely-spaced eyes (ocular hypetelorism), an abnormally wide nasal bridge, an enlarged lower jaw (mandible), and a "leonine" facial appearance (leontiasis ossea). Compression of certain nerves emerging from the brain (cranial nerves) may result in loss of some motor function (paralysis) in the facial area (cranial nerve palsy) and hearing loss (conductive and/or sensorineural hearing impairment). In addition, in individuals with the disorder, the long bones of the arms and legs may develop abnormally, resulting in unusual "club-like" flaring or broadening of the end portions (metaphyses) of the bones (metaphyseal dysplasia). In some cases, craniometaphyseal dysplasia may be inherited as an autosomal dominant genetic trait; in other cases, the disorder may have an autosomal recessive mode of inheritance.
