Diagnostic value of Fine Needle Aspiration Cytology in Parotid tumors.
J Pak Med Assoc Jan ;54(12):617-9.

Objective: To evaluate the usefulness and accuracy of fine needle aspiration cytology in the diagnosis of parotid gland tumors. Methods: We reviewed files of all patients who underwent parotidectomy for various parotid pathologies at Aga Khan University Hospital. Study design included a comparison between results of preoperative FNAC with final histopathological diagnosis. Galen & Ganbino method was used to calculate sensitivity and specificity of FNAC. Results: Among 50 patients reviewed, there was one false positive and 3 false negative results reported on FNAC. This gives a sensitivity of FNAC for reporting malignancy to be 74% and specificity to rule out malignancy 97%. No significant complications were reported while performing the procedure. Conclusion: FNAC is a safe and effective modality in diagnosis and treatment planning of patients with parotid tumors (JPMA 54:617;2004).
