The study of the etiopathological mechanism of the postural troubles with vertebral pain syndrome represent a field of research much controversial. The Authors report evident data of muscular and skeletal correlations between mandibular, maxillary and maxillomandibular asymmetries and skull base.

Abstract

Aims The Authors performed a research to define the physiopathological and clinical correlations between myoskeletal alterations of the stomatognathic apparatus and the cranio-cervical system in the subjects with maxillomandibular asymmetries. Materials and Methods 87 cases of maxillomandibular asymmetries (44 mandibular asymmetries, 28 maxillary asymmetries, 15 maxillomandibular asymmetries) with temporomandibular pain syndrome, vertebral and brachial pain and postural troubles are selected. Standardized CT and MR studies are performed to myoskeletal, articular and anatomical surgical evaluation of the dysmorphosis. The attention have been centred on the skull base and the cranio-vertebral structures. Results and Conclusions Anatomical and craniometric analysis allowed to individualize in the skull base two areas delimitated from the gleno-occipital-mastoid structures named by Authors “gleno-occipital-mastoid triangles”. The analysis of diagnostical imaging verified in all the cases the presence of three-dimensional spatial modifications of the skull base that involve particularly the structures of the gleno-occipital-mastoid triangle. The skull base loses its normal spatial position and morphological and spatial modifications of the glenoid temporal structures (asymmetry of the articular surfaces), the occipital condyles (morphological and spatial asymmetry) and the mastoid process (morphological asymmetry) ensue. Alterations of the pterygoid process are also present. The study of the etiopathological mechanism of the postural troubles with vertebral pain syndrome represent a field of research much controversial. The Authors report evident data of muscular and skeletal correlations between mandibular, maxillary and maxillomandibular asymmetries and skull base. This structure feels the effect of the asymmetrical condition of the facial structures. Considering his strategic function in the axial postural system, the results of this research appears very expressive.
