background and aim: it is well - known that sex hormones regulate bone metabolism. sex steroids increase osteoblasts activities and affect growth, remodeling and bone homeostasis. the aim of this study was to examine the effects of sex hormones deficiency on craniofacial growth in rats. methods & materials: fifty, thirty–day–old wistar rats comprised the sample in this experimental study. 25 ma...

Fibrous dysplasia (FD) is an osseous growth dis-order, producing immature bone and characte-rized by the replacement of normal bone with fibro-osseous connective tissue. It is a bone dys-plasia that has the potential to cause significant cosmetic and functional disturbances, particularly in the craniofacial skeleton. Cra-niofacial fibrous dysplasia is one of the three types of polyostotic fibro...

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...

Craniofacial growth is a scientific crossroad for the fundamental mechanisms of musculoskeletal physiology. Better understanding of growth and development will provide new insights into repair, regeneration and adaptation to applied loads. Traditional craniofacial growth concepts are insufficient to explain the dynamics of airway/vocal tract development, cranial rotation, basicranial flexion an...

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...

Children with reduced somatic growth may present various endocrinal diseases, especially growth hormone deficiency (GHD), idiopathic short stature (ISS), chromosomal aberrations, or genetic disorders. In an attempt to normalize the short stature, growth hormone (GH) is administered to these children. The aim of this literature review was to collect information about the craniofacial morphology ...

The study of growth and development of the facial profile is of interest to clinicians and researchers in the fields of pediatric dentistry, orthodontics, and craniofacial surgery, enabling diagnosis, planning, and evaluation of treatment. Until recently, craniofacial studies addressed facial growth, facial asymmetry, and gender differences by examining changes in size. However, size changes al...
