FNAC results of 127 patients, who also had permanent biopsy results, were evaluated according to age and localization of the pathology. The rates of accuracy, specificity, sensitivity, positive and negative predictive values were calculated.Results: During this period, 62.5% of the all FNACs were done on head and neck masses, and 12.9% of those to extra-thyroidal pathologies. Accuracy rates of FNAC were 94.3% for congenitaldevelopmental pathologies, 89.4% for infectious-inflammatory pathologies (93.5% for specific infections), and 83.7% for neoplastic pathologies (85.9% for malignancies). There were no statistically significant differences between the accuracy rates of FNAC according to patient's age and localization of the pathology. False negative rate was higher than false positive rate in malignant lesions. Correct diagnostic rate based on the cellular differentiation in the malignant pathologies was 50%.Conclusion: 1. FNAC has a high accuracy rate for head and neck masses. 2. FNAC should be first step of pathological examination in all head and neck masses with an intact overlying mucosa or skin. 3. There are no differences between the accuracy rates of the FNAC of the childhood or the adulthood period. 4. There are no differences between the accuracy rates of the FNAC of the pathologies of the neck or the salivary glands. 5. Clinically, FNAC should only be used as a guide for preliminary diagnosis, especially in malignant pathologies. Final treatment decision should not be made according to the results of FNAC and tissue biopsy should be obtained before definitive treatment.eninfo:eu-repo/semantics/closedAccessSalivary-gland lesionsPediatric headBiopsyDiagnosisFine-needle aspiration cytologyHead and neck massesSalivary glandsNeckMalignBenignCysticScience & technologyLife sciences & biomedicineOtorhinolaryngologyArticle00042100440000386934322667-7474
