The necessity of fine-needle aspiration biopsy (FNAB) in the diagnosis and treatment of parotid gland lesions is still contreversial. We examined the accuracy of cytology and histology in a review of 128 parotid gland tumors who underwent surgery with FNAB, n=102 and/or frozen section examination (FS), n=94. The diagnostic sensibility and specificity for malignant or benign lesions was respectively 81.5% and 97.5% for FNAB and 75% and 100% for FS as compared with definite histology (110 tumors were benign and 18 malignant). Insufficient material for FNAB evaluation was found in 12 patients mainly with small tumors (p= 0.043) or with tumors located in the deep process of the parotid gland (p= 0.029). Surgery was inapropriate (superficial lobe resection for malignant tumor) because of 4 false negative FS diagnoses. FNAB offers valuable information in the diagnosis of nonsurgical lesions and permits to avoid FS if FNAB identify a benign lesion. FS remains mandatory if FNAB evaluation is not possible or suggests a neoplastic tumor.
