Sensitivity and specificity of fine needle aspiration biopsy in parotid masses

Abstract

Objectives: We aimed to determine the sensitivity and specificity of fine needle aspiration biopsy FNAB in patients with parotid masses.Patients and Methods: The study included 29patients 15 males, 14 females; mean age 52 years; range 20 to 83 years who underwent FNAB and parotidectomy for parotid masses. After a detailed history taking, otorhinolaryngologic and systemic examinations were performed. Neck ultrasonogra- phy and, when needed, neck computed tomography were used. Superficial parotidectomy was per­ formed in 20 patients and total parotidectomy in nine patients.Results: The results of FNAB were reported as benign in 21 patients 72.4% , malignant in six patients 20.7% , and suspicious in two patients 6.9% . Postoperative histopathologic diagnoses were reported as benign in 17 patients 58.6% and malignant in 12 patients 41.4% .The sensitivity and specificity rates for FNAB were 54.6% and 100%, respectively. The most common histopathological diagnosis was pleomorphic adenoma n=7, 24.1% , followed by mucoepidermoid carcinoma n=4,13.8% , and VVarthin’s tumor n=3, 10.3% .Conclusion: Preoperative FNAB for parotid masses plays an important role in planning surgery.

Parotis kitlelerinde ince iğne aspirasyon biyopsisinin duyarlılık ve özgüllüğü

Abstract

Amaç: Parotiste kitle saptanan hastalarda ince iğneaspirasyon biyopsisinin İİAB tanısal duyarlılık veözgüllüğü değerlendirildi.Hastalar ve Yöntemler: Çalışmaya parotiste kitlenedeniyle İİAB ve parotidektomi uygulanan 29 hastaalındı. Tüm hastalarda ayrıntılı öykü alındıktansonra, kulak burun boğaz ve sistemik muayeneleryapıldı. Boyun ultrasonografisi ve gerektiğinde boyun bilgisayarlı tomografisinden yararlanıldı. Ameliyat öncesinde tüm hastalara İİAB yapıldı. Yirmi hastaya yüzeyel, dokuz hastaya total parotidektomi uygulandı. Bulgular: İnce iğne aspirasyon biyopsisi sonuçları 21hastada %72.4 benign, altı hastada %20.7 malign,iki hastada %6.9 kuşkulu olarak bildirildi. Ameliyatsonrası patoloji sonuçları 17 hastada %58.6 benign,12 hastada %41.4 malign idi. Parotis kitlelerinin değerlendirilmesinde İİAB’nin duyarlılığı %54.6, özgüllüğü %100 bulundu. Ameliyat sonrası patoloji sonuçlarına göre en sık rastlanan tümörler pleomorfik adenom n=7, %24.1 , mukoepidermoid karsinom n=4, %13.8 ve Warthin tümörü n=3, %10.3 idi.Sonuç: Parotis kitlelelerinde ameliyat öncesi İİAB yapılması cerrahi planlamada önemli bir role sahiptir
