بررسي ارزش تشخيصي FINE NEEDLE ASPIRATION BIOPSY در ضايعات راديولوسنت فكين

Diagnostic value of Fine Needle Aspiration Biopsy lesions of the jaw

Background and Aim: Fine Needle Aspiration Biopsy is an effective diagnostic method in the field of medical pathologies. Easiness, accuracy, validity and usefulness of this method have been verified frequently. This method is useful not only for soft tisse or even intraosseous lesions, but also recurrence of tumors (metastasis), resistence to treatment, verification of malignancy, differentiation between malignancy and benigiunent and determination of organisms causes infection. Unfortunately the use of this method is not common in dental pathology. So this study intendes to show the diagnostic value of FNA specially for intraosseous lesions causing jaw radiolucency. Methods and Materials: This investigation consisted of 80 patients who were referred to Taleghani General Hospital who were then referred to the pathology or surgery departments at Shahid Beheshti dental school. Cases consist of 29 females (36.25) % and 51 males (63.75%). Sample taking was conducted using a 10 cc, gauge 19 syringe. Results: Results show 90% sensitivity and 75% specificity for jaw radiotucent lesions in FNA method. Correlation between FNA and jaw radiolucencies was significant (P<0.001) and itʹs power was at equal accepctable Ievel according to cramerʹs V (phi - cramerʹs =0.623). Based on FNA cytology power, lesions with positive predictive value of 78.30 had a microscopic view compatible to the findings of other similar studies. Conclusion: FNA can be used as a reliable method for rapid, early and in expensive diagnosis, resulting in an on time, and appropriate treatment plan.
