[Comparison of the results of roentgenography, panoramic zonography and computer-aided tomography in some deformations of facial skull].

Fifty patients with congenital and posttraumatic deformations of the facial skull were examined using effective diagnostic schemes of x-ray examination (including panoramic roentgenography and sonography) and computer-aided tomography. The methods were found to supplement each other. Computer-aided tomography is more useful in posttraumatic deformations, for it helps specify the status of accessory nasal sinuses, detect the changes in the tissues of the eye-ball, optic nerve, and oculomotor muscles, and evaluate the consequences of craniocerebral injuries. The parameters obtained by three dimensional image reconstruction may be used for planning bone repair surgery.
