Objective:
To determine the utility of fine needle aspiration biopsy (FNA) in the evaluation of parotis lesions by comparing the results of preoperative FNA and postoperative pathology report results.
Material and Methods:
Preoperative FNA and postoperative histopathological results of 128 patients who had been operated for parotid masses between 2009-2014 were compared.
Results:
84 of the patients were male (%65.6) and 44 were female (%34.3). Mean age was 48 (range: 13-76). FNA was insufficient in 16 of the 128 patients (%12). FNA results in 96 of the remaining 112 patients were reported as benign. 88 of these (%91) were confirmed by postoperative histopathology. Of the 16 patients who were reported as malignant by FNA, 12 of them were confirmed postoperatively (%75). In evaluating histopathologically confirmed lesions, the absolute sensitivity in our patients was %75 and the specificity was %95.4. The positive predictive and the negative predictive values were %75 and %87.5 respectively. The accuracy rate was %85.7.
Conclusion:
FNA, as a reliable and effective method, can be used in the preoperative evaluation of parotid masses.
