[目的]探讨术前细针穿刺细胞学检查和术中冰冻活组织检查在腮腺肿瘤诊断中意义.[方法]在277例腮腺肿瘤患者中,给141例进行了术前细针穿刺细胞学检查,138例行术中冰冻活组织检查,将2种检查结果与术后常规病理检查结果进行比较分析.[结果]良、恶性肿瘤术前细针穿刺细胞学检查定性诊断率为88.65%,与术后病理检查结果诊断符合率为85.82%,其中良、恶性肿瘤诊断符合率分别为92.00%,37.50%;良、恶性肿瘤术中冰冻活组织检查定性诊断率为99.28%,与术后病理检查结果诊断符合率为97.10%,其中良、恶性肿瘤诊断符合率分别为98.45%,77.78%.[结论]术前细针穿刺细胞学检查和术中冰冻活组织检查可作为腮腺肿瘤常规检查方法.

OBJECTIVE To study the significance of preoperative fine needle aspiration cytology （FNAC） and intraoperative frozen section （FS） histopathology in the diagnosis of parotid tumors. METHODS Out of 277 patients with surgery of parotid tumors, 141 cases were performed with preoperative FNAC and 138 cases with intraoperative FS histopathology, and Both set of results were compared with the postoperative routine histopathological diagnosis. RESULTS The qualitative diagnosis rate of preoperative FNAC for benign and malignant tumor was 88.65%, and the diagnostic coincidence rate was 85.82% as compared with postoperative histopathologic diagnosis, and the diagnosis coincidence rate for benign and malignant tumor was 92.00% and 37. 50%, respectively. The qualitative diagnosis rate of intraoperative FS histopathology for benign and malignant tumor was 99.28 %, and the diagnostic coincidence rate was 97.10 % as compared with postoperative histopathologic diagnosis, and the diagnosis coincidence rate for benign and malignant tumor was 98. 45 % and 77.78 %, respectively. CONCLUSION The preoperative FNAC and intraoperative FS histopathology should be as the routine inspection method for parotid gland tumors.
