The fontanelles may remain open until adulthood, but the sutures often close with interposition of wormian bones. Bosses of the frontal, parietal, and occipital regions give the skull a large globular shape with small face. The characteristic skull abnormalities are sometimes referred to as the "Arnold head" named after the descendants of a Chinese who settled in South Africa and changed his name to Arnold. More than 100 additional anomalies may be associated, including wide pubic symphysis, dental abnormalities, short middle phalanges of the fifth fingers, delayed skeletal maturation, hearing deficiency, and mild mental retardation in some cases. Major Features Head and neck: Brachycephaly with bossing of the frontal, parietal, and occipital bossing give the head a large globular appearance with a small face because of smallness of the maxillary and zygomatic bones and relative prognathism. Additional abnormalities include open fontanels; open cranial sutures; calvarial thickening in the supraorbital part of the bone, squama of the temporal bones, and the occipital bone; wormian bones filling suture lines, occasional absence of the parietal bones, faulty development of the foramen magnum, and dysplasia of the paranasal sinuses and mastoids.
Extractions: Radiographic signs include: Skull has wormian bones and delayed or absent closure of the fontanelles Clavicles - total or partial absence of one or both clavicles Pelvis - absent or dysplastic pubic bones, femoral neck dysplasia, wide SI joints, iliac hypoplasia Hands - long 2nd metacarpal and metatarsal, short distal phalanges DDX: References: See References Chapter.

Extractions: Cleidocranial Dysplasia ( cleido = collar bone, + cranial = head, + dysplasia = abnormal forming) , also known as Cleidocranial Dysostosis and Marie-Sainton Disease, is a condition characterized by defective development of the cranial bones and by the complete or partial absence of the collar bones (clavicles). Characteristics include: Delayed closure (ossification) of the space between the bones of the skull (fontanels) Premature closing of the coronal suture Protruding jaw (mandible) and protruding brow bone (frontal bossing) Wide nasal bridge due to increased space between the eyes (hypertelorism) High arched palate or possible cleft palate Short stature Scoliosis of the spine There is no link between anything the mother did or did not do while she was pregnant and the occurrence of Cleidocranial Dysplasia. It is transmitted as an autosomal dominant trait. The cause is not yet known, but several chromosome abnormalities have been linked with this syndrome, including chromosome 6p21.

Cleidocranial dysplasia (CCD) is a genetic (inherited) disorder of bone development which is characterized by: Absent or incompletely formed collar bones (the "cleido-" part refers to the clavicles, the collar bones). A person with this condition can bring his/her shoulders together or nearly so; and Typical cranial and facial abnormalities with square skull, late closure of the sutures of the skull, late closure of the fontanels (the soft spots), low nasal bridge, delayed eruption of the teeth, abnormal permanent teeth, etc. How does a person acquire CCD? The disorder is transmitted genetically in an autosomal dominant manner. This means that one parent with the condition has a 50:50 chance of passing CCD to each of their children. Boys and girls are equally affected. What is the molecular genetic basis for CCD?

Other characters Cleidocranial dysplasia, a rare congenital defect characterized by deficient ossification of bone, particularly mid line bone formed in membrane. The condition is transmitted as an autosomal dominant trait with widely variable phenotypic expression. The classical site of the abnormality is the clavicle which may show a spectrum of radiographic appearances ranging from hypoplasia of the mid third of clavicular shaft to complete absence of the clavicle. This clavicular dysplasia is most prominent in the lateral aspect of the clavicle. Clinically the shoulders droop forward and are excessively mobile. Children with complete bilateral absence of the clavicle can approximate their shoulders anteriorly ( Fig.1 ). Radiographs may show a range of other abnormalities. The head may be large with frontal bossing, delayed or absent closure of fontanelle ( Fig.2 ) and widened sutures with persistent metopic suture and multiple Wormian bones. Permanent teeth may be delayed in eruption and maldeveloped, the palate may be narrow and high arched and the sinuses hypoplastic. The thorax may be narrow and bell-shaped with incomplete ossification of the sternum. There may be absent or dysplastic pubic bones with resultant pubic diastasis ( Fig.3

Other characters Cleidocranial dysplasia, an autosomal dominant disorder with numerous clinical findings, including mild shortening of stature, large brachycephalic head, small face, and high, arched palate with delayed eruption of supernumerary teeth. In addition, the patient may have genu valgum and short fingers. Radiographic features reveal poorly ossified skull, widening of the sutures and multiple wormian bones. In some patients the foramen magnum is deformed, and basilar impression is often evident. Absence of the clavicle (partial or total) may be observed ( Fig.1 ). Other findings include hypoplastic scapula, bell-shaped thorax and pelvic changes (delayed ossification of the pubic bones, a wide symphysis pubis and narrow iliac wings). Coxa valga or coxa vara deformity may also develop, and in some cases spina bifida occulta is present. The hands and wrists also may be involved.
