Associations between the Cervical Vertebral Column and Craniofacial Morphology.

Sonnesen L - Int J Dent (2010)

Bottom Line: Conclusion.It is suggested that fusion of the cervical vertebral column is associated with development and function of the craniofacial morphology.This finding is expected to have importance for diagnostics and elucidation of aetiology and thereby for optimal treatment.

ABSTRACT
Aim. To summarize recent studies on morphological deviations of the cervical vertebral column and associations with craniofacial morphology and head posture in nonsyndromic patients and in patients with obstructive sleep apnoea (OSA). Design. In these recent studies, visual assessment of the cervical vertebral column and cephalometric analysis of the craniofacial skeleton were performed on profile radiographs of subjects with neutral occlusion, patients with severe skeletal malocclusions and patients with OSA. Material from human triploid foetuses and mouse embryos was analysed histologically. Results. Recent studies have documented associations between fusion of the cervical vertebral column and craniofacial morphology, including head posture in patients with severe skeletal malocclusions. Histological studies on prenatal material supported these findings. Conclusion. It is suggested that fusion of the cervical vertebral column is associated with development and function of the craniofacial morphology. This finding is expected to have importance for diagnostics and elucidation of aetiology and thereby for optimal treatment.

Illustrations of morphological deviations of the upper cervical vertebral column. F: Fusion is defined as fusion of one unit with another at the articulation facets, neural arch, or transverse processes. O: Occipitalization is defined as assimilation, either partially or completely, of the atlas (C1) with the occipital bone. P: Partial cleft is defined as failure to fuse of the posterior part of the neural arch. D: Dehiscence is defined as failure to develop of part of a vertebral unit.

Mentions: Fusion anomalies are fusion, block fusion, and occipitalization [43]. Fusion is defined as fusion of one unit with another at the articulation facets, neural arch, or transverse processes (Figure 1). Occipitalization is defined as assimilation, either partially or completely, of the atlas (C1) with the occipital bone (Figure 1). The definition of block fusion has been modified according to Sonnesen and Kjær [48] and defined as fusion of more than two units at the vertebral bodies, articulation facets, neural arch, or transverse processes.
