Computerized tomography examination for the detection of positional changes in the temporomandibular joint after...

Changes in the position of the temporomandibular joint following sagittal splitting osteotomy of the mandibular ramus with screw fixation were examined using computerized tomography. Ten patients were involved in the study. Rotational movement of the condyle-bearing fragment was most commonly seen in the transverse computer tomograms. However, the use of screw fixation seems to cause no major malpositioning of the condyle-bearing fragment.
