  • Abstract
  • Look Inside

 The preoperative diagnosis of the parotid gland tumors in 31 patients was evaluated. The results were as follows ; leakage of contrast media in sialogram of the parotid gland usually suggests malignant tumor. But, a few histologically proven benign tumors showed also leakage, so the relationships among the duct, capsule and parenchym were reexamined from the extirpated specimens. The ultrasonic examination was very useful for the differential diagnosis between benign and malignant tumor. But the standardization of this procedure requires some experiences. The repeated sialograms after the first trial might have shown leakage in malignant tumor, but no leakage in benign ones. So, this procedure is evaluated to be useful in the differential diagnosis.
