Sensitivity and specificity of fine needle aspiration biopsy in parotid masses

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 29
patients (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 ultrasonography
and, when needed, neck computed tomography
were used. Superficial parotidectomy was performed
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 Warthin’s tumor (n=3, 10.3%).
Conclusion: Preoperative FNAB for parotid masses
plays an important role in planning surgery.
