Title: Craniocervical junction as a focus for craniofacial growth studies. Author: Huggare J. Journal: Acta Odontol Scand; 1995 Jun; 53(3):186-91. PubMed ID: 7572095. Abstract: The craniocervical junction is a highly specialized unit simultaneously supporting head during movements in all planes and protecting the spinal cord. Anatomically, it includes an atlantoaxial complex, part of which embryonically arises from the occipital region of the skull. This review deals with the gross anatomy, kinematics, and growth reactions associated with functional alteration in this complex. Particular attention is paid to the atlas, the connecting element between the head and the vertebral column proper. From several studies it is concluded that the horizontal growth of the atlas is regulated by synchondroseal growth, whereas the vertical growth is determined by appositional growth. Some vertebral anomalies and concomitant anomalies of the cranial base are reported, to point out the ontogenetic integration between the skull base and the craniocervical junction. The high frequencies of atlantal posterior arch deficiency in cleft palate patients have led to speculations about common etiologic factors in these conditions.[Abstract] [Full Text] [Related] [New Search]
