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...
Craniofacial reconstruction aims at estimating the facial outlook associated to an unknown specimen. Craniofacial reconstruction is generally based on the statistical tissue thickness on anthropometric landmarks. However, the features points alone are not enough for realistic reconstruction. So, in our paper, we take advantage of a reference facial model, through measuring the differences betwe...
OBJECTIVE To review the cephalometric studies investigating the craniofacial morphology of the parents of children with cleft lip and/ or palate (CL(P)). METHODS A review of the literature has been conducted using MedLine sources dated 1970-2005. The Cleft Palate-Craniofacial Journal has been searched manually. The reference lists of all previous publications were consulted to identify any pu...
Fibrous dysplasia is a benign bone disease first described by Lichtenstein in 1938. It is characterized by progressive replacement of normal bone with fibro-osseous connective tissue. When the disease involves craniofacial skeleton, it results in significant disfigurement and other functional problems. This paper reports a case of large craniofacial fibrous dysplasia involving zygomaticomaxilla...
INTRODUCTION Craniofacial orthodontics has been shown to be a critical component of the care of patients with craniofacial anomalies such as cleft lip and palate. Thus, the purpose of this study was to assess the perceptions and clinical experience in cleft and craniofacial care, of orthodontic residents in Nigeria. METHODOLOGY Questionnaires were sent out to orthodontic residents in the six ...
