CCD (cleidocranial dysplasia) is a kind of rare congenital skeletal dysplasia and deformity. It has rare clinical syndrome, such as forehead radius, small maxilla ofa cial, wide long distance eye, collapse nose, widening cranial suture, incompleted closure of the frontal, clavicle hypoplasia, increased range of shoulder motion and other abnormalities. Often accompanied by teeth hypoplasia or impacted, through a careful observation of the clinical morphology, case history and X-ray examination can confirm the diagnosis. 展开更多
