Studies of the sialogram of 49 cases of tumor of the parotid glands performed by the author from 1950 to March, 1957 have revealed the following findings: 1. In cases of benign tumor, the presence of stenosis, dilatation or abnormal distribution of the ductal system was found, and the absence of shadows was observed in sialograms of type VIII 1. 2. In cases of malignant tumor, sialograms showed discontinuation or intermittent brea-king-off of the duct and the seepage of the contrast medium into the adjacent tissue, and the absence of shadows was observed in sialograms of type VIII 2. The seepage of the contrast medium was noted also in the residual gland. 3. In view of the fact that examination or treatment which had been given before the sialography was performed made the picture confused, sialography should be performed prior to the start of a treatment. 4. It is sometimes impossible to determine the nature of the tumor by means of sialog-raphy. Nevertheless, it is important that an accurate diagnosis should be made concerning the extent and the location of the tumor before it is referred for surgery. And acccurate diagnosis of a tumor is not possible without sialograpey. 5. In taking the sialograms of the tumor, no only lateral view but also anteroposterior view should be taken. If it seems necessary, anteroposterior tomography should also be perfo-rmed.
