“…In studies evaluating sonography for assessing disk position [14][15][16][17][18][19][20] and type of internal derangement [18], the technique was found to be highly accurate. Differences occurred when disk displacements were evaluated separately at different mouth opening positions.…”

“…Although some reports about the use of sonography in diagnosing disk displacements and condylar osteoarthrotic changes have been published [13][14][15][16][17][18][19][20][21][22], there are, to our knowledge, no data of prior studies using cadaver sections to verify the sonographic results. The purpose of the present study was to evaluate the accuracy of HR-US in detecting disk displacement and condylar erosion of the TMJ by using corresponding cryosections as a "gold standard.…”

Pathologic-sonographic correlation in temporomandibular joint pathology

The accuracy of high-resolution ultrasonography (HR-US) in detecting disk displacement and condylar erosion of the temporomandibular joint (TMJ) was evaluated, using corresponding cryosections as a "gold standard". HR-US of the TMJ was performed with a high frequency 12 MHz transducer on 30 preserved autopsy specimens. Succeeding sonography, the autopsy specimens were deep-frozen and cut in paracoronal planes corresponding to the sonographic images. HR-US diagnoses were compared with cryosectional findings in a blinded fashion. HR-US detected 19 (95%) of 20 instances of condylar erosion and 16 (73%) of 22 instances of disk displacement. There were one false-positive finding for condylar erosion and two false-positive findings for disk displacement. The accuracy of HR-US evaluating condylar erosion and disk displacement rated 93% and 73%, respectively. In conclusion, condylar erosion was reliably assessed by HR-US, but the evaluation of disk position was less accurate.

Imaging diagnosis of the temporomandibular joint: critical review of indications and new perspectives

et al. 2009

View full text Add to dashboard Cite

In recent decades, there have been important developments in temporomandibular joint (TMJ) imaging. New techniques complement preexisting methods, and each modality is indicated for specific conditions in accordance with the clinical diagnosis. The aim of this review is to give an overview of conventional and new techniques in TMJ imaging. The literature review includes studies published between 1976 and 2009 that appear in the Medline database. Magnetic resonance imaging remains the ''gold standard'' modality for TMJ analysis. It allows structures to be visualized without radiation whether or not they are mineralized; however, it is costly and complex. Ultrasonography, an alternative method with increasing importance in TMJ analysis, is a simple, noninvasive, and low-cost technique that allows for the visualization of the position of the disk; however, it does not detect condylar abnormalities. Reconstructions in three-dimensions can be obtained with computed tomography, magnetic resonance imaging, and ultrasonography and can be used to obtain rapid prototyping biomodels. Health professionals performing TMJ imaging exams should consider clinical history and findings, exam cost, radiation exposure, results of previous exams, and whether the current result will influence diagnosis and treatment planning.

Results. Patients with >5 peripheral affected joints showed significantly more sonographically diagnosed destructive changes in the TMJ than did patients with <5 affected joints. There was no significance between the number of affected peripheral joints and disc dislocation in the closed-mouth position. In the maximum open-mouth position, there was a significant correlation between the number of affected peripheral joints and disc dislocation. Patients with a JIA duration >23 months had a significantly higher rate of disc dislocation and destructive changes. Patients with a JIA duration >60 months had a significantly higher rate of destructive changes of the TMJ than patients with a disease duration <60 months, but no statistical significance was found concerning disc dislocation. Conclusion. The significant correlation between pathologic sonographic findings, duration of JIA, and the number of affected peripheral joints make the technique interesting for use as a diagnostic screening method.
