Temporomandibular joint: comparison of single- and double-contrast arthrography.


Lower-space, single-contrast arthrography and dual-space, double-contrast arthrotomography were sequentially applied to 58 fresh temporomandibular joint (TMJ) autopsy specimens, and the findings were compared with observations in corresponding cryosections. Both modalities had high accuracy rates (greater than or equal to 84%) and no statistically significant differences between the two techniques were found. A side-by-side comparison of the two types of arthrograms, however, revealed that video tape recording of lower-space, single-contrast arthrography was superior in demonstrating joint dynamics and that dual-space, double-contrast arthrotomography was superior in demonstrating the soft-tissue anatomic features of the joint. It appears that lower-space, single-contrast arthrography can be recommended for examination of patients with clicking, catching, and intermittent locking, and that dual-space, double-contrast arthrotomography is preferable when information about morphologic alterations is clinically more important than information about joint dynamics.
