Morphological Evaluation of Cranium Facial Asymmetry in Class III Malocclusion Patients

The maxillofacial region of patients with facial asymmetry is deformed not only in the mandible but also maxilla, suggesting that head may be deformed. Therefore, this study, skeletally originated mandibular prognathism was evaluated relation to cranial morphology. morphology who visited Chiba Dental Center Tokyo College and were diagnosed skeletal (asymmetry group: ANB 0° or less; Menton deviation 4 mm more; 30 subjects) without (symmetry less than 0°; 3 mm) measured evaluated. As a method, length area cranium using axial cephalometric radiographs. In group, there significant difference left–right long diameter posterior part compared symmetry group (p = 0.009). had differences central occipital areas on left right sides < 0.001). direction coincided about 70% cases. There positive correlation between amount deviation. results study suggested greater deformity asymmetry.
