Cephalometric findings in three cases of cleidocranial dysostosis

Three cases of cleidocranial dysostosis, involving one boy and two girls 13 to 15 years of age, were analyzed cephalometrically. All the cases were characterized by real maxillary prominence in addition to mandibular prognathism. Although the skeletal development of the face in the present cases was atypical rather than typical of cleidocranial dysostosis, the possible individual variation should be noticed when a person with abnormal skeletal development is analyzed cephalometrically for diagnostic purposes.
