Maxillary expansion is one of the earliest methods of obtaining space used in the field of orthodontics. Maturing craniofacial sutures along with the increase in bone density and rigidity are main causes of high resistance of the maxilla to transversal expansion forces applied to the midpalatal suture through orthodontic appliances. Fifty-three patients, with a mean age of 16.4 years and a diagnosed transverse plane orthodontic anomaly were included in this study and divided in two groups: male group and female group. Cone-beam computed tomography (CBCT) was used for measurements conducted in order to determine bone density before and after jaw expansion in different segments of the midpalatal suture: anterior, middle and posterior. In males, slightly higher bone density values were observed in the midpalatal suture than in females before and after maxillary expansion, with average values ranging from 128.5 Hounsfield units (HU) to 672.9 HU. Bone density along the maxillary suture plays an ...
Metopism is the condition of having a persistent metopic suture, or persistence of the frontal metopic suture in the adult human skull. The premature fusion of cranial sutures named craniosynostosis, it is simple when only one cranial suture is involved and compound when two or more cranial sutures are involved. Metopism is the opposite of craniosynostosis. The main factor of the metopic suture is to increase the volume of the anterior cranial fossa. The frontal bone includes the forehead, and the roofs of the orbits (bony sockets) of the eyes. The frontal bone has vertical portion (squama) and horizontal portion (orbital part). Some adults have a metopic or frontal suture in the vertical portion. In uterine period in right and left half of frontal region of the fetus there is a membrane tissue. On each half a primary ossification center appears about the end of the second month of the fetus. Primary ossification center extends to form the corresponding half of the vertical part (squama) and ...
CRANIOSYNOSTOSIS. Craniosynostosis is a birth defect of the Skull (which may affect the Brain) that is characterized by the premature closure of one or more of the fibrous joints between the bones of the Skull (called the cranial sutures) before Brain growth is complete. While the premature fusion of the cranial sutures results in disproportionate growth of the cranial bones, it may also affect the growth of the facial bones. When a suture is fused there is no growth in a plain perpendicular to the line of the suture. The abnormally shaped Skull that results is due to the Brain not being able to grow in its natural shape because of the closure. Instead it compensates with growth in areas of the Skull where the cranial sutures have not yet closed.. The Skull has two different components, the first of which forms the vault of the Cranium and is called the membranous part. The other portion, the chondrocranium forms the Base of the Skull. After a certain age there is little likelihood of ...

During craniofacial development, the Hedgehog (HH) signaling pathway is essential for mesodermal tissue patterning and differentiation. The Hedgehog family consists of three protein ligands: Sonic Hedgehog (SHH), Indian Hedgehog (IHH), and Desert Hedgehog (DHH), of which two are expressed in the craniofacial complex (IHH and SHH). Dysregulations in HH signaling are well documented to result in a wide range of craniofacial abnormalities, including holoprosencephaly, hypotelorism, and cleft lip/palate. Furthermore, mutations in HH effectors, co-receptors, and ciliary proteins result in skeletal and craniofacial deformities. Cranial suture morphogenesis is a delicate developmental process that requires control of cell commitment, proliferation and differentiation. This review focuses on both what is known and what remains unknown regarding HH signaling in cranial suture morphogenesis and intramembranous ossification. As demonstrated from murine studies, expression of both SHH and IHH is critical to the

This study provides normative values of anthropometric cranial indices that are clinically useful for the evaluation of multiple types of craniosynostosis and introduces 2 new indices that are useful in the evaluation and management of metopic and bicoronal synostosis. The authors hypothesize that normative values of the new indices as well as for established measures like the cephalic index can be drawn from the evaluation of CT scans of normal individuals. METHODS: High-resolution 3D CT scans obtained in normal infants (age 0-24 months) were retrospectively reviewed. Calvarial measurements obtained from advanced imaging ...
The joints between the craniofacial bones (sutures) are vital for proper brain and craniofacial development and have recently been identified as a niche for stem cells. The Centers for Disease Control and Prevention, National Birth Defects Study has published data suggesting that environmental exposures including maternal thyroid diseases, maternal nicotine use, and use of selective serotonin reuptake inhibitors (SSRIs) in pregnant mothers may exacerbate incidence and or severity of craniofacial anomalies including craniosynostosis. Craniosynostosis is a birth defect defined as the premature fusion of the suture(s) of the skull occurring in 1:1800-2500 births. A proposed mechanism of craniosynostosis is the disruption of the balance of proliferation and differentiation of cells in the perisutural area leading to bone overgrowth. The newly identified stem cell population characterized as Gli1+ may be the target of pharmacological exposures that result in aberrant craniofacial growth. For these ...

The extent to which cranial bones will be able to go is considered controversial and research of your existence and diploma of cranial motion have yielded blended results.[14] Cranial sutures are the parts during which the eight cranial bones are joined. Through infancy, the cranial bones will not be rigidly fused to each other,[22] but are in its place certain with each other by a membrane often called a fontanelle the place two sutures be a part of. Concerning the 1st and 2nd year of lifetime, the cranial bones begin to move jointly and fuse as a standard part of progress.[14] Studies inspecting the age of the closure from the cranial sutures have noted combined results ...

There are four major sutures and one of them is the coronal suture. These sutures are what connect the brains frontal, temporal, parietal and occipital bones. Though it looks like the brain is one large bone, there are actually a number of major bones in the brain that are connected together. These bony plates covering the brain are being held together by a fibrous material which is called sutures. In this article, what we will be discussing about is the coronal suture and its function..

The upper jaw holds the key in many ways to facial beauty and proper function of the lower face and teeth. It should be wide and full to accommodate all fourteen normal teeth (excluding third molars) in proper alignment and provide proper lip support. When the patient is giving a full smile, he or she should not show an excessively gummy smile or expose dark triangles between the teeth and the cheeks. This result can be accomplished with slow maxillary expansion (SPE), as the cranial sutures, including the mid-palatal suture, remain viable throughout life.. The following case is a good example of the use of FFO to expand the maxilla to an ideal shape to create a handsome, movie star smile. This patient was 16 years old when treatment began. He had substantial crowding of his front teeth. His upper jaw was narrower than what is considered ideal. Traditional orthodontics typically would have recommended the removal of four first bicuspid teeth and then straightening of the remaining teeth with ...
Craniosynostosis. It often is related to the development of the bones of the skull but can also involve the surrounding tissues of the scalp. The borders where these plates come together are called sutures or suture lines. Diseases or conditions that cause an abnormal increase in the pressure within the head can cause the sutures to spread apart. Consult with your doctor for an accurate diagnosis. The result is a symmetrically shaped head. Other tests that may be required are blood tests and a spinal tap. The larger anterior fontanelle lies at the intersection of the sagittal, coronal, and metopic sutures and closes by the end of the second year. There is no one definitive method for preventing suture separation. We just noticed today that my baby has what seems to be a separation of the skull on the left side of her head, running at a slight angle vertically. Correspondingly, the size of the cranium of an infant born at term is 40 percent of adult size; by seven years, this increases to 90 ...

Predicated on our results, we hypothesize that both and could end up being implicated in the pathogenesis of CS in human beings. However, further research are had a need to establish the precise pathomechanism underlying advancement of the defect. genes (OMIM). Various other less regular disorders derive from different mutations in the genes (Jabs et al. 1993; Twigg et al. 2009, 2013; Hurst et al. 2011; Keupp et al. 2013; Sharma et al. 2013; Kutkowska-Kazmierczak et al. 2018). Conversely, small is well known about hereditary etiology of isolated CS and in nearly all cases the root molecular defect continues to be unidentified.

Endoscopic surgery was associated with lower estimated blood loss (p , 0.001), shorter length of stay (p , 0.001), and shorter operating time (p , 0.001). From the literature review of the 10 studies, transfusion rates for endoscopic procedures were consistently lower, with significant differences in 4 of 6 studies; the cost was lower, with differences ranging from $11,603 to $31,744 in 3 of 3 studies; and the cosmetic outcomes were equivocal (p , 0.05) in 3 of 3 studies. Finally, endoscopic techniques demonstrated complication rates similar to or lower than those of open surgery in 8 of 8 studies. ...
During postnatal calvarial growth the brain grows gradually and the overlying bones and sutures accommodate that growth until the later juvenile stages. The whole process is coordinated through a complex series of biological, chemical and perhaps mechanical signals between various elements of the craniofacial system. The aim of this study was to investigate to what extent a computational model can accurately predict the calvarial growth in wild-type (WT) and mutant type (MT) Fgfr2C342Y/+ mice displaying bicoronal suture fusion. A series of morphological studies were carried out to quantify the calvarial growth at P3, P10 and P20 in both mouse types. MicroCT images of a P3 specimen were used to develop a finite element model of skull growth to predict the calvarial shape of WT and MT mice at P10. Sensitivity tests were performed and the results compared with ex vivo P10 data. Although the models were sensitive to the choice of input parameters, they predicted the overall skull growth in the WT and MT

Craniosynostosis is a rare condition in which an infant has an abnormally shaped skull after the cranial sutures fusing too early. Surgery can correct it.
At a deep level of our physiological functioning all healthy, living tissues subtly breathe with the motion of life - a phenomenon that produces rhythmic impulses which can be palpated by sensitive hands. The presence of these subtle rhythms in the body was discovered by osteopath Dr William Sutherland over 100 years ago, after he had a remarkable insight while examining the specialized articulations of cranial bones. Contrary to popular belief Dr Sutherland realized that cranial sutures were, in fact, designed to express small degrees of motion. He undertook many years of research during which he demonstrated the existence of this motion and eventually concluded it is essentially produced by the bodys inherent life force, which he referred to as the Breath of Life. Furthermore, Dr Sutherland discovered that the motion of cranial bones he first discovered is closely connected to subtle movements that involve a network of interrelated tissues and fluids at the core of the body; including ...

Squama (squama frontalis).-Surfaces.-The external surface (Fig. 134) of this portion is convex and usually exhibits, in the lower part of the middle line, the remains of the frontal or metopic suture; in infancy this suture divides the bone into two, a condition which may persist throughout life. On either side of this suture, about 3 cm. above the supraorbital margin, is a rounded elevation, the frontal eminence (tuber frontale). These eminences vary in size in different individuals, are occasionally unsymmetrical, and are especially prominent in young skulls; the surface of the bone above them is smooth, and covered by the galea aponeurotica. Below the frontal eminences, and separated from them by a shallow groove, are two arched elevations, the superciliary arches; these are prominent medially, and are joined to one another by a smooth elevation named the glabella. They are larger in the male than in the female, and their degree of prominence depends to some extent on the size of the frontal ...
