Fine-needle aspiration in the diagnosis of salivary gland disorders in the community hospital setting.

From 1983 to 1988, 47 patients with salivary gland disorders were assessed with fine-needle aspiration (FNA) before surgery. The preoperative fine-needle diagnoses were then compared with the postoperative pathologic findings. In the same period, 63 patients from two other community hospitals who had been evaluated preoperatively with FNA were studied retrospectively. The overall sensitivity of FNA for salivary neoplasms was 80.6%. Fine-needle aspiration was more sensitive in identifying benign tumors (88.4%) than malignant neoplasms (58.3%) and was least sensitive in identifying nonneoplastic salivary diseases (35.3%). Pleomorphic adenomas were correctly identified preoperatively in 96.2% of cases, whereas for malignant neoplasms, the diagnostic accuracy was highest for mucoepidermoid carcinoma (50%). To demonstrate the strengths of FNA as a diagnostic tool, as well as to delineate its limitations, we present our 5-year experience. Our FNA results are similar to those reported by the major European and American referral centers. Because our medical centers are community based, our results may more accurately reflect those seen by otolaryngologists in private practice. To date, no evidence of tumor seeding along the FNA tract has been reported.
