Abstract
OBJECTIVE: To evaluate the effectiveness of FNAC in the diagnosis of parotid gland masses. METHODS: Fine needle aspiration cytology was performed in 121 patients with parotid gland masses. Among them, 62 were males, 59 were females. Their age ranged from 5 to 95 years with an average age of 57.88 years. The cytological results were compared with postoperative histopathological results and follow-up outcomes. RESULTS: The qualitative diagnostic accuracy of FNAC was 92.56% (112/121) and the overall diagnostic accuracy was 89.26%. The sensitivity for tumors was 91.25%, and the specificity was 100%. 7 patients were false negative with a false negative rate of 8.75%. The sensitivity and specificity for benign and malignant lesions was 70.97% and 100%, respectively. 9 patients were false negative with a false negative rate of 29.03%. There were no false positive cases, nor clinical complications. CONCLUSIONS: FNAC plays an important role in the diagnosis of parotid gland masses. It is a cost-effective, safe, helpful and accurate tool for establishing tissue diagnosis as a primary investigative modality in the diagnosis of lesions in the parotid gland region with higher accuracy and fewer complications.
