[The combination of computed tomography with sialography to diagnosing lesions of the parotid gland ].

32 patients with lesions of the parotid region underwent CT-sialography; 7 of these cases were selected to demonstrate the clinical usefulness of this diagnostic method. CT sialography allows to differentiate deep-lobe parotid tumors and parapharyngeal tumors. CT is also very good for estimation of the tumor size, which contributes to therapy planning. Basing on CT findings the operability of malignant tumors can be determined. CT sialography provides valuable information in cases with special diagnostic problems.
