Current trends in research on craniofacial syndromes have led to enhanced interest in the cranial base as a contributory factor in the development of normal and abnormal midfacial structure. Indeed, attention has focused upon one particular growth plate in the posterior cranial base, the spheno-occipital synchondrosis, since it has been shown that alterations in this structure are associated wi...

BACKGROUND/OBJECTIVES Although secular trends have been well documented in the craniofacial region, there is no evidence to suggest that these temporal changes exist in samples used for orthodontic research. The aim of this study is to determine the effect of secular trends on craniofacial growth in a series of longitudinal birth cohorts that are frequently used in orthodontic research. MATER...

In orthopedic treatment an attempt is being made to influence the morphology of the craniofacial skeleton. According to Wolff’s law, “the structure and shape of a bone becomes progressively adapted to all the changing mechanical forces exerted on the bone; as a whole bone represents function and responds to stress placed on it”. The sutures in the craniofacial skeleton are remodeled as secondar...

In the description of craniofacial growth it is crucial to identify constant geometric relations. The search leads to complex manipulations of coordinate data from cephalograms. In the regularities that he finds, the clinician must be aware of the difference between empirical contingency and geometric necessity. For instance, common procedures for identifying centers away from which growth proc...

Sleep-disordered breathing (SDB) in children could be resolved by adenotonsillectomy (T&A). However, incomplete results are often noted post-surgery. Because of this partial resolution, long-term follow-up is needed to monitor for reoccurrence of SDB, which may be diagnosed years later through reoccurrence of complaints or in some cases, through systematic investigations. Children undergoing T&...

Differences in craniofacial anatomy among racial groups have been documented in a variety of structures, but the oral and maxillofacial regions have been shown to be a particularly defining region of variability between different racial/ethnic groups. Such comparisons are informative, but they neither address developmental changes of the craniofacial anatomy nor do they assess or take into acco...
