Abstract

Objective: To analyze Fine Needle Aspiration Cytology’s diagnostic accuracy in Parotid Gland Neoplasms by taking the Post-Operative Histopathology Results as a Gold Standard.

Study Design: Prospective Longitudinal Study.

Place and Duration of the Study: Department of Ear, Nose, Throat, Head and Neck Surgery, Dow University of Health Sciences, Dr Ruth K.M Pfau Civil Hospital, Karachi, Pakistan, from Sep 24 to May 25.

Methodology: Analysis was performed on 123 patients who underwent parotidectomy due to a parotid gland lump. The study included all participants who were between the ages of 18 and 75 and who had a suspicion of a parotid gland tumor. The exclusion criteria included any patient with a history of previous parotid gland surgery, autoimmune disease, chronic granulomatous condition, or any inflammatory condition of the parotid gland.

Results: Among the 123 patients enrolled, benign tumors were observed in 89 cases (72.4%), whereas malignant tumors were identified in 34 cases (27.6%). When preoperative fine needle aspiration cytology results were compared to the final histopathology, the FNAC revealed diagnostic accuracy of 92.68%, sensitivity of 85.29%, specificity of 95.51%, positive predictive value of 87.88%, and negative predictive value of 94.44%

Conclusion: Our study suggests that FNAC has good sensitivity and specificity and is a relatively accurate method in diagnosing parotid gland neoplasms. Thus, it can be a useful resource for preoperative counselling on the characteristics of the neoplasms and their outcomes as well.
