[Analysis of erroneous diagnosis on temporomandibular joint arthrography].

In the present study, 433 arthrographic cases with temporomandibular joint dysfunction syndrome were included. 30 cases of them underwent operation and 22 cases underwent digital subtraction arthrographic examination after conventional arthrography. It has been found that arthrographic erroneous diagnosis could be made because the artificial manifestations caused by over-dose of contrast medium into the joint cavity, repeated puncture, anterior displacement of the condyle after injecting contrast medium and so on. In addition, the arthrographic manifestations of dis-clock were also analysed.

[Evaluation of digital subtraction arthrography on the diagnosis of temporomandibular joint dysfunction syndrome].

Digital subtraction arthrography of temporomandibular joint superior cavity (TMJSC-DSA) was performed for 70 cases with TMJ dysfunction syndrome. A comparative observation between the operative findings and the findings of TMJSC-DSA examination was carried out for 11 cases who underwent TMJ operation. The results showed that TMJSC-DSA could overcome the disadvantages of conventional arthrography and make exact diagnoses for the anterior displacement of the disc and the disc perforation.

Radiographic, pathological and operative observations of cases with TMJ disturbance syndrome.

A group of 30 operative cases (32 sides) with TMJ disturbance syndrome was included in the present study. The authors carried out a comparative study between radiographic, pathological and operative observations for these cases. Based on this study, we are confident that the nature of the organic destructive stage of the TMJ disturbance syndrome is essentially a secondary degenerative arthrosis, and that those cases showing transient PDS are probably functional and reversible; however, the indolent and deferred cases with internal derangement of TMJ actually belong to earlier manifestations of degenerative arthrosis.
