Development of three-dimensional craniofacial cephalometric analysis for virtual planning in orthognathic surgery.
Cone beam computed tomography is taken for diagnosis independently from this study. Investigators are using this medical imaging for performing the 3D cephalometric analysis. Investigators apply a set of well described landmarks of three-dimensional reconstruction of the skull from patients suffering from diverse craniofacial malformations. Then a set of specific measurements is taken from the patient and provide insights how to modify the anatomy of the patient to improve the skull's architecture and symmetry
