DISEASES of the salivary glands have received scant attention in medical literature. Except for tumors and calculi, knowledge of other abnormalities of the salivary glands remains meager. Patients with recurrent pain and swelling of one or both parotid or submaxillary glands require study by other than the usual clinical methods. An additional means of diagnosis, by injecting a radiopaque medium into the duct system and parenchyma of the two chief salivary glands, parotid and submaxillary, is available and should be utilized when the diagnosis is obscure.
Radiopaque materials were injected into Stensen's duct as early as 1904, but the procedure was considered a medical curiosity of no clinical significance until 1926. In that year Carlsten1 studied normal and pathologic parotid glands roentgenologically, using iodized oil injected into Stensen's duct. Since then many reports have been published, with various attempts to correlate the clinical and roentgen findings.
