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.
对58个新鲜颞下颌关节（TMJ）尸体解剖标本依次进行低位单对比关节造影和双位双对比关节断层摄影，并将结果与相应冷冻切片的观察结果进行比较。两种方法的准确率都很高（大于或等于84%），且两种技术之间未发现统计学上的显著差异。然而，对两种关节造影片的并排比较显示，低位单对比关节造影的录像在显示关节动态方面更具优势，而双位双对比关节断层摄影在显示关节软组织解剖特征方面更具优势。似乎低位单对比关节造影可推荐用于检查有弹响、卡顿和间歇性绞锁的患者，而当形态学改变的信息在临床上比关节动态信息更重要时，双位双对比关节断层摄影则更可取。
