Background: We aimed to investigate the sensitivity of the frequently used preoperative diagnostic test FNAC (fine needle aspiration cytology) in thyroid diseases by analysing the correlation between this test and histopathological examination in the light of our clinical experience. Materal and Methods: The medical records of 355 thyroid patients who underwent bilateral total thyroidectomy operation in the 2nd General Surgery Clinic of Ankara Numune Training and Research Hospital between 2006 January- October 2010 were reviewed. The detection rate of malignancy by fine-needle aspiration biopsy prior to thyroidectomy in terms of specificity and sensitivity were retrospectively analyzed. The diagnostic tests performed in the preoperative period of the patients, including thyroid function tests, US, scintigraphy and thyroid FNAC results were correlated with postoperative histopathological examination results. Findings: The results of FNAC in 167 cases were as follows; benign in 97 (58%), suspicious in 50 (29.9%), insufficient material in 11 (6.6%) and malignant in 9 cases (5.4%). The sensitivity and specificity of FNAC in our study were 83% and 100% respectively. Results: According to the data presented in this study, determination of the need for operation and verification of malignancy supports the use of FNAC. But a negative FNAC result should not impede the indication of thyroidectomy which is planned by the results of other diagnostic tests. The extension of resection should be decided by analyzing of risk factors and by findings of the neck eksploration.
