Craniofacial clefts have an incidence of 1/700 [...]
Forensic artists use tissue thicknesses at well known landmarks on the craniofacial skeleton to generate a potential likeness of an individual from a skull. This is a very subjective and time consuming process. We present two prototype software packages: one for simulating the growth of a craniofacial skeleton either forwards or backwards in time, and the other for generating a facial reconstru...
BACKGROUND Citation analysis is a recognized scientometric method of classifying cited articles according to the frequency of which they have been referenced. The total number of citations an article receives is considered to reflect it's significance among it's peers. METHODS Until now, a bibliometric analysis has never been performed in the specialty of craniofacial anomalies and craniofaci...
The quantification, analysis, prediction and simulation of the growth of the craniofacial complex is discussed in the context of a two-dimensional coordinate model of craniofacial morphology. Data accumulated from lateral X-ray films (cephalograms) are used, in conjunction with the model, to describe and analyze craniofacial growth; to predict the future size of craniofacial structures, the fut...
Synchondrosis is defined as the development of a union between two bones by the formation of either hyaline cartilage or fibro-cartilage. This paper reviews the relationship between cranial base synchondroses and craniofacial development. The cranial base synchondroses are important growth centers of the craniofacial skeleton. Their abnormalities lead to numerous growth and developmental condit...
The term craniofacial anomalies literally encompasses all congenital deformities of the cranium and face. More specifically, however, the term has come to imply congenital deformities of the head that interfere with physical and mental well-being (Marsh and Vannier, 1985). There are practically no epidemiological studies of craniofacial malformations as such. Myrianthopoulos (1982) reviewed dat...
Objective: Silybum marianum has been used for centuries in herbal medicine for treatment of liver diseases. Currently, there is no data available on the possible effects of silymarin on fetal development. This study aimed to investigate the teratogenic effect of silymarin on BALB/c mice fetuses. Materials and Methods: A total of 40 pregnant mice were divided into 4 groups of 10 mice each. Three...
BACKGROUND Inactivating mutations in tissue-nonspecific alkaline phosphatase (TNAP) cause hypophosphatasia (HPP), which is commonly characterized by decreased bone mineralization. Infants and mice with HPP can also develop craniosynostosis and craniofacial shape abnormalities, although the mechanism by which TNAP deficiency causes these craniofacial defects is not yet known. Manifestations of H...
Sutures, where neighboring craniofacial bones are separated by undifferentiated mesenchyme, are major growth sites during craniofacial development. Pathologic fusion of bones within sutures occurs in a wide variety of craniosynostosis conditions and can result in dysmorphic craniofacial growth and secondary neurologic deficits. Our knowledge of the genes involved in suture formation is poor. He...
Craniofacial superimposition, although existing for one century, is still a controversial technique within the scientific community. Objective and unbiased validation studies over a significant number of cases are required to establish a more solid picture on the reliability. However, there is lack of protocols and standards in the application of the technique leading to contradictory informati...
