    Abstract:
    BACKGROUND: To retrospectively compare the accuracies of ultrasound-guided fine-needle aspiration (USFNA) and ultrasound-guided core needle biopsy (USCNB) in the diagnosis of parotid masses. METHODS: A total of 171 patients (aged 17-86 years, mean 54 years) with parotid masses (35 malignant and 136 benign lesions) underwent either USFNA (n = 107) or USCNB (n = 64). The diagnostic accuracies for differentiating benign from malignant lesions of both examinations were compared. Surgical histopathology (n = 104) and clinical diagnosis (n = 67) were used to establish the final diagnoses. RESULTS: USCNB had a significantly higher sensitivity (94.1%) than USFNA (55.6%) (p < 0.05) in differentiating benign lesions from malignant conditions. The specificity and overall accuracy of USCNB were higher than those of USFNA (100% and 98.4% versus 93.3% and 86.9%, respectively). USCNB provided more specific diagnosis than USFNA (100% versus 93.3%, p < 0.05). All six patients with lymphomas who underwent USCNB were accurately diagnosed, whereas all four patients with lymphomas who underwent USFNA were not. CONCLUSIONS: USCNB should be preferred to USFNA when a definite diagnosis of a parotid solid mass is needed.
