AB : The author examined fifty cases of sialolithiasis diagnosed in the Dept. of Oral Radiology in SNUH by conventional radiography and sialography, and patient's age, sex, location, radiodensity, numbers, shapes, and relation with ducts a nd parenchymas.
The results of this study were as follows:
1. The average age of patients was 38.6 years in submandibular sialolithiasis, and 39.2 years in parotid sialolithi asis.
2. There was slightly higher incidence in males (58.0%) than in females (42.0%).
3. Salivary stones were found to be much more in the submandibular gland and duct (82.0%) than in the parotid gland and duct (18.0%). 4. Of 62 submandibular salivary stones, 33 (53.2%) occurred in the main duct, 25 (40.3%) occurred in the hilum, and 4 (6.5%) occurred in the parenchyma. Of 18 parotid salivary stones, 9(50.0%) occurred in the main duct, 5(27.8%) occurred in the parenchyma, and 4(22 .2%) occurred in the hilum.
5. Of the submandibular salivary stones, the number of radiopaque type was 45(75.8%), and the number of radiolucen t type was 17(24.2%). Of the parotid salivary stones, the number of radiopaque type was 12 (66.7%), and the number of radiolucent t ype was 6(33.3%).
6. The single type was 30 cases (73.2%) in submandibular gland, 6 cases (66.7%) in parotid gland, and the multiple type was 11 cases (26.8%) in submandibular grand, and 3cases (33. 3%) in parotid gland.
7. Round shape was 35 cases (43.8%), ovoid shape was 22 cases (27.5%), irregular shape was 17 cases (21.3%), and cylindrical shape was cases (7.5%).
