Accuracy of Computerized Axiography Controlled by MRI in Detecting Internal Derangements of the TMJ

Giedre Kobs, Olaf Bernhardt, Georg Meyer

Summary

Objectives: To evaluate the diagnostic accuracy of 3-D computed axiography to detect anterior disk displacements (ADD) of the temporomandibular joint (TMJ).

Methods: 564 joints with no disk displacement (NDD), 114 joints with reducible displaced disk (RDD) and 36 joints with permanently displaced disk (PDD) confirmed on magnetic resonance imaging (MRI) were examined by 3-D computerized axiography. The assessment of TMJ disk position was based on the sagittal MRI plane (the position of the disk was controlled by coronal images).

Results: Pathological TMJ states on axiography could be demarcated with sensitivity of approximately 80% end specificity of approximately 90% from healthy joints.

Conclusion: Within the limitations of this study we suggest, that jaw-tracking devices remains an accurate evaluation method for determination of TMJ dysfunction.

Key words: temporomandibular disorders; craniomandibular disorders; internal derangement; computerized axiography; magnetic resonance imaging; sensitivity; specificity
