The role of fine-needle aspiration (FNA) in salivary gland lesions as a preoperative diagnosis has always been under scrutiny. Several studies have shown that frozen section (FS) is accurate for pathological diagnosis and decision-making during the surgery. This study has been carried out to assess the accuracy of FNA and FS in parotid surgeries.
All parotid lesions removed between July 1998 and June 2003 by the Department of Otolaryngology, Head and Neck unit at Monash Medical Centre were reviewed. FNA, FS and definitive pathology were collected and discrepancies were identified.
Eighty-five parotid tumours had been removed. Thirty-three were malignant in which squamous cell carcinoma was the most common. FS was able to differentiate benign tumours from malignant with 100% accuracy (30 cases). FS was able to alter the surgical decisions in six cases. FNA had been carried out in 62 cases, with sensitivity and specificity of 77.2 and 90%, respectively.
Frozen section in parotid surgery is accurate, inexpensive and may add important information that alters management and improves the outcome. The use of FS routinely in parotid surgery is recommended.
细针穿刺抽吸活检（FNA）在涎腺病变术前诊断中的作用一直受到审视。多项研究表明，冰冻切片（FS）在手术期间的病理诊断和决策方面是准确的。本研究旨在评估FNA和FS在腮腺手术中的准确性。
回顾了1998年7月至2003年6月间莫纳什医疗中心耳鼻喉头颈科切除的所有腮腺病变。收集了FNA、FS和最终病理结果，并确定了差异。
共切除85例腮腺肿瘤。其中33例为恶性，最常见的是鳞状细胞癌。FS区分良性肿瘤和恶性肿瘤的准确率为100%（30例）。FS在6例病例中改变了手术决策。62例进行了FNA，敏感性和特异性分别为77.2%和90%。
腮腺手术中的冰冻切片准确、廉价，可能会提供重要信息，从而改变治疗方案并改善预后。建议在腮腺手术中常规使用FS。
