Fine-needle aspiration is a widely accepted method in the preoperative evaluation of head and neck tumors. However, its effectiveness in the interpretation of salivary gland disorders is controversial.
To evaluate the effectiveness of FNA as a preoperative diagnostic tool of parotid lesions.
Reports of 52 FNA from various parotid gland lesions were compared with the final pathologic diagnoses.
We noted 31 true positive, 5 true negative and 16 false negative results. There were no false positive FNA reports. The calculated sensitivity, specificity and accuracy of FNA diagnosis in this study were 66%, 100%, and 69.2% respectively.
The high rate (30.8%) of false negative FNA results was partly explained by sampling errors, therefore specificity of the procedure could be improved by the precise selection of a representative aspiration site.
细针穿刺抽吸术是头颈部肿瘤术前评估中广泛接受的方法。然而,其在唾液腺疾病诊断中的有效性存在争议。
评估细针穿刺抽吸术(FNA)作为腮腺病变术前诊断工具的有效性。
将52例各种腮腺病变的FNA报告与最终病理诊断进行比较。
我们注意到31例假阳性、5例假阴性和16例假阴性结果。没有FNA报告为假阳性。本研究中FNA诊断的计算敏感性、特异性和准确性分别为66%、100%和69.2%。
FNA假阴性结果的高发生率(30.8%)部分由采样误差解释,因此通过精确选择有代表性的抽吸部位可提高该检查的特异性。
