Abstract
Thirty six cases with parotid gland tumors were treated in our clinic from June, 1989, to December, 1993. Histological examination showed 29 benign and 7 malignant tumors. Of the 7 malignant tumors, 5 were primary parotid cancers and 2 were metastatic tumors. To evaluate the accuracy of ultrasonically guided fine needle aspiration cytology (FNAC) and Ga scintigraphy as preoperative diagnostic method, the results of these diagnosis were analysed. The accuracy of FNAC for parotid grand tumor was 96%, and Ga scintigraphy 62%. Therefore, FNAC was very useful in preoperative pathological diagnosis and was also useful to decide the treatment of the tumors. There were no effect of chemothrapy for the 4 cases of primary malignant tumors. This suggests that surgical treatment is nesessary for malignant parotid tumors, and total par-otidectomy or extensive total parotidectomy would be necessary for high-grade malignant tumors. When total parotidectomy or extensive total parotidectomy was performed, the reconstruc-tion method such as the facial nerve grafting, the face lifting and cheek suspension would be effective to obtain better facial nerve function.
