Abstract

Objective: To determine the sensitivity, specificity, positive predictive value, negative predictive value and overall accuracy of FNAB in detecting parotid malignancies in our institution.

Methods:

Design:           Retrospective Chart Review

Setting:           Tertiary Government Hospital

Participants: Postoperative records of seventy six (76) patients with tumors of the parotid gland preoperatively diagnosed by FNAB.

Results: The sensitivity of FNAB was 46%. The specificity and positive predictive value were both 100% and negative predictive value was 90%. Overall accuracy in diagnosing malignant parotid tumor was 91%.

Conclusion: FNAB in this institution is a poor predictor of malignancy, having a sensitivity rate of only 46%. While this may serve as a basis for not recommending pre-operative FNAB for patients with parotid tumors in the interim, other factors should also be considered, including concerns with the actual performance and interpretion of FNAB in our institution.
