To investigate the relation between disc displacement of the temporomandibular joint and skeletal structure, 85 patients with jaw deformity were examined by magnetic resonance imaging with respect to disc position and cephalometric analysis.
Disc displacement was found in 48 (61 joints) of 85 patients. No significant correlation was found between the presence of disc displacement and the results of cephalometric analysis, except for the perpendicular distance from the facial midline to the mental spine (p<0.01). These results indicate that mandibular asymmetry might affect the prevalence of disc displacement of the temporomandibular joint on the deviated side.
