Characterised by abnormal development of cranial and nasal bones, craniosynostosis (premature coronal suture fusion), and other extracranial anomalies (limb polydactyly and syndactyly).
Many of the more profound craniofacial deformities occur secondary to craniosynostosis or premature fusion of one or more cranial sutures. Reconstruction of craniofacial structure is typically required when physical or mental well-being becomes affected. The pathogenesis, diagnosis, and surgical management of craniosynostosis are reviewed here.
Craniosynostosis or premature suture fusion is a wide spread disorder occurring in 300–500 out of 1,000,000 live births. In humans, premature closure of cranial base synchondroses or sutures followed by reduced growth of the skull along the rostral–caudal axes has been implicated in both syndromic and single suture craniosynostoses.
Postnatal growth occurs in two ways: at the sutures that connect the maxilla to the cranium and cranial base by surface remodeling.

Cranial sutures are deformable joints between the bones of the skull, bridged by of the bone-suture structure were developed in abaqus/explicit cae (simulia,.
Expansion forces at the sutures lead to expansion of bone and thus growth of craniofacial skeleton. Cranial vault increases in size via the primary growth of bone that happens at the suture. Sicher theorized that tissues such as periosteum cartilage and sutures are growth centers just like epiphysis of the long bone that allow the bone to form.
This allows the bone to enlarge evenly as the brain grows and the skull expands.
Mar 27, 2017 in humans, cranial sutures normally fuse between 20 and 30 years of one of the most commonly used growth factors for craniofacial bone.
Premature closing of the seams (sutures) between the bones of the skullcausing distortion and underdevelopment of parts of the skull and often the face (usually midface). Conditions resulting from this are separated into two major categories: single suture craniosynostoses—may occur spontaneously or may be inherited through autosomal dominance.

Craniofacial sutures are a ubiquitous feature of the vertebrate skull. Previous experimental work has shown that bone strain magnitudes and orientations often vary when moving from one bone to another, across a craniofacial suture. This has led to the hypothesis that craniofacial sutures act to modify the strain environment of the skull, possibly as a mode of dissipating high stresses.
Craniosynostosis is a condition in which the sutures close too early, causing problems with normal brain and skull growth.

Cranial sutures are fibrous joints providing a malleable quality to the head, allowing vaginal birth and growth of the brain during early development.
Undifferentiated cells between these osteogenic bone fronts form the cranial vault sutures, which function to keep the suture patent while allowing rapid and continual bone formation at the edges of the bone front until brain growth is complete. 10 sutures are fibrous “joints” that allow temporary deformation of the skull during parturition.
Throughout postnatal craniofacial development, sutures function as sites of bone growth, accommodating expansion of a growing brain.
Sutures are more than just fibrous joints between the bones in our skull. They are active growth sites that influence the development, growth and shaping of our face and cranium. When suture development is disrupted, craniosynostosis can result, a condition which is characterized by the premature closure of one or more cranial sutures before brain growth is complete and leads to an abnormally shaped skull.
Sutures are greatly involved in both normal craniofacial growth and developmental anomalies. Having clear parameters for defining their morphology is fundamental to properly investigate their physiological or pathological development. However, the current literature is lacking of well‐defined methods for the assessment of these structures.

Sutures are not merely articulations between bones they are primary sites of osteogenesis mediating much of the growth of the face and skull vault. In this chapter the development of sutures will be described including the origin of sutural tissues, the determinants of suture location, and suture morphology.
Cranial vault sutures, the fibrous tissues uniting the bones of the skull, are the major sites of bone growth along the leading margins of the cranial bones during craniofacial development, especially during rapid expansion of the neurocranium (baer, 1954). To function as bone growth sites, sutures need to remain patent, while allowing rapid.

Craniosynostosis is a congenital deformity of the infant skull that occurs when the fibrous joints between the bones of the skull (called cranial sutures) close prematurely. Due to this closure, the baby develops an abnormally shaped skull because the bones do not expand normally with the growth of the brain.
The overall bone development from cranial sutures occurs in a direction perpendicular to the long axis of the suture.
Craniofacial sutures are fibrous joints between bones of the skull. Within them, osteoblasts differentiate at the borders of a central suture mesenchyme and are incorporated into growing bone at osteogenic fronts in the highly regulated process of osteogenesis.

Abstract intramembranous bone growth is achieved through bone formation within a periosteum or by bone formation at sutures. Sutures are formed during embryonic development at the sites of approximation of the membranous bones of the craniofacial skeleton. They serve as the major sites of bone expansion during postnatal craniofacial growth.
