Abstract

Background: Fine needle aspiration (FNA) before surgery is needed in clinical diagnosis and treatment of parotid gland tumors. Objective: This study aimed to determine the diagnostic value of fine needle aspiration biopsy (FNA) and of its contribution to the management of parotid gland tumors. Methods: We conducted a retrospective study of 60 patients who had undergone parotidectomy as well as preoperative fine needle aspiration biopsy. Results: Results of the fine-needle aspiration cytology: 21,7% of the cases were evaluated as non-diagnostic. FNA melanoma diagnosis results accounted for 8.3%. The histopathological examination: benign tumors in 96.6%; cancer in 3.4%. The value of utrasound in the parotid gland tumors: The sensitivity 100%; The specificity 94,8%; Diagnostic accuracy was 95%, Positive predictive value was 40% and negative predictive value 100%. Diagnostic value of FNA in the parotid gland tumors: The sensitivity 100%; The specificity 93,3%; Diagnostic accuracy was 93,6%, Positive predictive value 40% and negative predictive value 93,6%. Conclusion: FNAC generally provided the correct histological diagnosis for benign tumors. However, poor sampling techniques lead to an unidentified diagnosis.
