Abstract
BACKGROUND: 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. OBJECTIVES: To evaluate the effectiveness of FNA as a preoperative diagnostic tool of parotid lesions. METHODS: Reports of 52 FNA from various parotid gland lesions were compared with the final pathologic diagnoses. RESULTS: 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. CONCLUSIONS: 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.
