[Clinical Application of CT  assisted Double Contrast Arthrography of Temporomandibular Joint]
OBJECTIVE:To introduce double-contrast arthrography of TMJ with reformatted sagittal and coronal CT imaging and to evaluate the value of its application in the diagnosis of temporomandibular joint dysfunction. METHODS: 14 patients in whom diagnosis can not be established with conventional arthrography were examined by double  contrast arthrography with reformatted sagittal and coronal CT imaging. RESULTS: In double-contrast arthrography with CT imaging, 1 case was normal;1 case had anterior displacement with reduction;2 cases were anterior displacement without reduction, and 8 cases were with disk adhesion. CONCLUSION:The double  contrast arthrography with reformatted sagittal and coronal CT imaging was a very important alternative to conventional arthrography, and has special value to demonstrate adhesion of TMJ.
