超声介导下细针穿刺活检在腮腺肿瘤术前诊断中的应用价值

目的分析超声介导下细针穿刺活检(USFNA)在腮腺肿瘤术前诊断中应用的价值。方法回顾性分析2011年10月至2013年10月间外科就诊的腮腺肿瘤患者120例,所有患者术前均行USFNA诊断,并与术后病理学诊断比较。结果 USFNA定性诊断总相符率为92.5%,与病理学诊断完全一致的总准确率为74.2%。其中良性肿瘤定性诊断相符率为92.9%,准确率为77.4%;恶性肿瘤定性诊断相符率为91.7%,准确率为66.7%。结论 USFNA鉴别良恶性腮腺肿瘤安全快速,准确率高,临床并发症少,是术前重要的常规检查之一。

The value of ultrasonography guided fine-needle aspiration cytology in the preoperative diagnosis of parotid tumors

Objective To evaluate the value of ultrasound-guided fine-needle aspiration （USFNA） in the preoperative diagnosis of parotid tumors. Methods 120 cases with parotid tumors admitted to our department of oral and maxillofacial surgery were analyzed retrospectively. Preoperative USFNA findings were compared with the final pathologic diagnosis of the surgically resected specimen. Results The total coincidence rate of distinction of benign and malignant tumors by USFNA was 92. 5% ,and the overall agree- ment of the cytologic and pathologic diagnosis was 74. 2%. Those of benign lesions were 92. 9% and 77.4%, and of malignant tumors were 91.7% and 66. 7%. Conclusion USFNA is a safe and effective ex- amination with higher accuracy and fewer complications in differencing the malignant and benign tumor of the parotid region,which is an important routine test before operation.
