title: The combined computerized tomography-sialogram. A technique to differentiate deep lobe parotid tumors from extraparotid pharyngomaxillary space tumors.
abstract: The preoperative differentiation of a deep lobe parotid tumor from a parapharyngeal tumor is important to the surgeon in determining the correct surgical approach. The combined parotid sialogram and CT scan provide more information than either study alone, and we feel that a reliable preoperative differentiation can be made on this combined study.
