Temporomandibular joint disc position in the sagittal and coronal plane. A macroscopic and radiological study
(1996)- Abstract
- TMJ autopsy specimens were studied macroscopically and arthrographically with respect to the disc position in the sagittal and the coronal planes. After single-contrast arthrography of the lower joint space, the specimens were cryosectioned. The arthrographic findings were correlated with the morphological findings. Anterior disc position was found in about two thirds and sideways disc displacement in about one third of the joints. Some of the sideways displaced discs also exhibited an anterior displacement, hence a rotational disc displacement. Superior disc position was associated with biconcave disc configuration and anterior disc position with disc deformation (p<0.001). Perforation of the disc or posterior attachment was more... (More)

Anterior disc position was found in about two thirds and sideways disc displacement in about one third of the joints. Some of the sideways displaced discs also exhibited an anterior displacement, hence a rotational disc displacement. Superior disc position was associated with biconcave disc configuration and anterior disc position with disc deformation (p<0.001). Perforation of the disc or posterior attachment was more frequent in joints with complete anterior disc position than in other joints (p<0.03). The diagnostic outcome of arthrography in diagnosing anterior disc position in the sagittal plane was high, with a positive predictive value of 0.88 and a negative predictive value of 0.78. In diagnosing a perforation, the corresponding figures were 0.80 and 1. The diagnostic outcome of arthrography in diagnosing sideways and rotational disc displacement was low, both in the sagittal and in the anteroposterior projection.
Studies on imaging of TMJ disc position published from 1978 to 1994 were reviewed. More than 400 studies on arthrography, CT and MRI were found. Only about 7 % of the studies presented the diagnostic outcome of the method described. In diagnosing anterior disc position, arthrography exhibited the highest likelihood ratio for a positive test, 4.5 as compared with 2.3 for MRI and 2.1 for CT. In diagnosing sideways and rotational disc displacement, MRI showed the highest outcomes, with a likelihood ratio for a positive test of 9.3, as compared with 3.8 for arthrography. (Less)
