The radiographic examination of 8526 patients revealed the presence of 92 cases of calcifications in the soft tissue of the head and neck. The examinations were made from April 1982 to June 1986 at Okayama University Hospital attached to Dental School. The purpose of this study wass retrospectively to evaluate the clinical radiographic features of these calcified lesions.
The results are as follows;
1. The most frequent calcifications in the submandibular region were sialoliths and phleboliths were found most frequently in the cheek areas.
2. In the cases of sialoliths, two-thirds had only one calcified body per person. More than two calcified bodies were mostly found in the cases with phleboliths or calcifications of lymph nodes.
3. Layer or eyeball-like patterns were mostly found in the cases of phleboliths with the size more than 2mm in a short diameter. Homogeneous, mottled or small nuclear patterns predominated in the cases of sialoliths.
4. Calcifications of lymph nodes with more than 2mm in a short diameter showed irregular shape and border as compared with sialoliths and phleboliths.
