| Popis: | The attenuation number of the TMJ disk was measured in direct sagittal computerized tomograms (CTs) of eight fresh TMJ autopsy specimens. The CT attenuation number was correlated to histologic observations of hyalinization, calcification, and cartilaginous metaplasia of the disk. Correlations were found between high CT attenuation numbers and the presence of hyalinization, calcification, and foci of cartilaginous metaplasia in the disks. The results suggest that the high CT attenuation number of a disk might be associated with hyalinization, calcification, and metaplastic cartilage formation. |
