Computerized tomography with simultaneous sialography in evaluating parotid tumors

Abstract

In an effort to improve on the amount of preoperative information obtainable, computerized tomography was combined with contrast sialography in the evaluation of parotid masses. Experience to date is limited to 17 patients, but this combination of techniques seems to demonstrate clearly the margins of the tumor, whether or not there is extraparotid extension, whether the mass is medial or lateral to the facial nerve, and whether or not the mass will hamper access to the main trunk of the facial nerve.
