[Evaluation of the panoramic sialography in the diagnosis of salivary gland diseases].

Pantomographic sialography (PS) and traditional sialography (TS) was performed and compared on 106 glands out of 94 patients. The main advantages of pantomographic sialography are: (1) sialectasic lesions of the salivary glands are shown well; (2) small lesions of the main salivary glands are shown well: (3) lesions of the main salivary ducts are shown well; (4) the imaging distortions are minor and the actual situation can be demonstrated well; (5) superimposition of surrounding tissues is avoided, the imagings are more clear; (6) more than one glands can be examined at the same time; and (7) patients are positioned easily and feel more comfortable.
