Accuracy of the oblique lateral transcranial projection, lateral tomography, and x-ray stereometry in evaluation of mandibular condyle displacement.
Condylar displacement similar to that occurring during and after mandibular ramus osteotomies was simulated in an in vitro study. Three different radiographic methods were used to measure the displacement, and the accuracy of the methods was compared. The stereometric method was more accurate than the plain radiographic methods and permitted measurements in all three dimensions. The oblique lateral transcranial projection was more accurate than lateral tomography, possibly because identification of measurement points in lateral tomography was complicated by the substantial displacement of the condyle.
