Use of Fine Needle Aspiration Biopsy in Diagnosis Oral and Maxillo-Facial Tumors

Abstract

The Technique of fine needle aspiration biopsy (F.N.A.B.) was evaluated in the field of maxillofacial surgery. For this purpose comparison of cyt ological results with the conventional histo pathological results were take place. Seventy-two specimens were obtained by F.N.A.B. from 60 patients with age range from 3-84 years of both sexes, 11.7% of the patients had previous history of diagnosed malignant tumors. Cytological results show 40 cases(55.5%) were benign tumor, 27 cases (37.5 %) were malignant, 3 cases (4.2 %) unsatisfactory for diagnosis and 2 cases (2.8 %) were suspicious to be malignant. The statistical analysis showed that F.N.A.B. had sensitivity (92.6%), specificity (100%), positive predictive value (92.3%), and accuracy rate (96%).
