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 ...
BACKGROUND Referred craniofacial pain of cardiac origin might be the only symptom of ischemic heart accidents. This study aimed to determine the frequency of craniofacial pain in patients with ischemic heart disease. MATERIAL AND METHODS This cross-sectional study was accomplished on 296 patients who met the criteria of having ischemic heart disease. Data regarding demographics, medical histo...
Orbital defects after tumor resection (exenteration of orbital content) have been traditionally reconstructed with adhesive-retained craniofacial prostheses, also known as epistheses. The breakthrough in rehabilitation of facial defects with implant-retained prostheses has come with development of modern silicones (vynilpolysiloxane) and bone anchorage called osseointegration. Craniofacial impl...
OBJECTIVE To develop an integrated approach for engineering craniofacial scaffolds and to demonstrate that these engineered scaffolds would have mechanical properties in the range of craniofacial tissue and support bone regeneration for craniofacial reconstruction. EXPERIMENTAL VARIABLE Scaffold architecture designed to achieve desired elasticity and permeability. Scaffold external shape desi...
