closure, its progress and age relationship part 2 ectocranial closure in adult males of white stock.
Age estimation was based on tooth-wear patterns and Cranial Suture
have been principally interpreted as indicators of maturity in odontocete mammals, although it has been demonstrated that it is not possible to generalize their usefulness as maturity indicators, because each species seems to express its own pattern of cranial suture
closure across age or size (e.
These include: the inion process, the mastoid process, the frontal ridges, the dentition (Miles, 1958), the dental arch, the shape of the chin, the shape of the angular process, the zygomatic arch, the cranial sutures
, and the overall thickness of the cranial bones (Bass, 1971).
sup] recommended using easily palpable skull landmarks (such as zygomatic root, inion, and mastoid process), not cranial sutures
, to identify the locations of the transverse and sigmoid sinuses.
CCD is characterized by short stature, large head with frontal and parietal bossing, delayed closure of cranial sutures
and fontanels, hypertelorism with depressed infraorbital area, broad based nose with depressed nasal bridge and aplasia or varying degrees of hypoplasia of clavicles.
Neurocranial growth is largely determined by growth of the brain and reaches 90% of adult head size by age 12 months; growth slows and cranial sutures
are generally fused at age 24 months.
A cephalohematoma is blood collection under the periosteum of a given cranial bone and, due to this anatomic location, is confined by the cranial sutures
50) Hence Jagged1 maintains osteoblastic precursor cells undifferentiated and therefore it keeps cranial sutures
and craniometric points detected on MRI.
The condition involves premature closure of the cranial sutures
, either single or multiple, and may be simple or part of a syndrome (Table 2).
Craniofacial anomalies are grouped into two categories, those which involve failure of fusion or disruption of the embryological units leading to facial clefting, or those which involve premature closure of cranial sutures
leading to craniostenosis.
Craniosynostosis is premature fusion of one or more cranial sutures
, often resulting in an abnormal head shape.

of an infant's skull.
