Description

The clinical features of 100 patients (82.0% benign, 18.0% malignant) with parotid gland tumors treated (operated, in principle) from January 2003 to December 2007 were retrospectively investigated. Approximately 85% of cases which were benign were pleomorphic adenoma (54.9%) and Warthin's tumor (30.5%). The pathological types of malignancy were various. If malignancies were accompanied by whole parotid gland tumors as one group, it accounted for 88% in these three groups. Moreover, by addition of basal cell adenomas to make it about 96% and based on the clinical findings and so on, mainly based on the diagnostic imaging, we created a preoperative (pathologically) diagnostic flow-chart. In the diagnostic imaging, MRI (contrast enhancement) and nuclear medicine inspection (99mTcO4, especially) were useful. However, 67Ga-citrate was not useful. Ultrasonic-guided FNA or needle biopsy (when absolutely necessary, within 2 weeks preoperatively) was additionally used for a patient which wavers about the operative indication and the one which needs preparation due to the choice of reconstruction method after resection and so on.
