Introduction: Fine needle aspiration (FNA) is an useful tool for the diagnostic evaluation of patients with a cervical mass, because of its feasibility and safety. Aim: To determine the accuracy of FNA cytology in our hospital over the last ten years. Material and method: A retrospective and descriptive study. Data were obtained from patients undergoing FNA in the Department of Otolaryngology, Hospital Barros Luco Trudeau from 2001 to 2010 and compared with the corresponding histology report of the original surgical specimen. Results: A total of 197 FNA procedures were performed in 143 patients. A definite cytological diagnosis was made in 140 patients (71%%). 77 patients had corresponding histology samples. The sensitivity was 46%%, specificity 85%%, positive predictive value 74% and negative predictive value 62%. The location for which we obtained a better performance of the technique was in salivary glands and the best performing diagnosis was squamous cell carcinoma. Discussion: FNA is an underused diagnostic tool with a high rate of non diagnostic samples. It is useful to rule out malignancy in salivary gland masses and metastatic squamous cell carcinoma in lymph nodes.
