Introduction and proposed study: Numerous deforming syndromes of the craniofacial complex involve also the symmetry of the cranial base. This study considers a particular alteration, that of 'scoliosis', in which the line Nasion-Sella-Basion-Inion is not rectilinear but curved, due to a torsion of the cranial base in the horizontal plane. Materials: Plagiocephaly was studied in one patient, which was probably caused by altered timing or mechanism of closure of the cranial sutures. Methods: This study was carried out using CT images of the patient's craniofacial complex, using standard neuroradiological points. In order to study the forces that operated in the various complexes, a mathematical analysis was applied namely, a finite element system analysis (FESA). Results: From this mathematical study, which has enabled us to evaluate the forces that operate in determining the deformity, it has been possible to locate two sites of force concentration. They were located at different levels and on opposite sides. Conclusion: This finding could explain why the middle and lower thirds of the face were also involved. © 2004 European Association for Cranial-Maxillofacial Surgery.
