Abstract

OBJECTIVE/HYPOTHESIS: Fine needle aspiration (FNA) is an accurate, cost-effective tool for the study of salivary gland lesions. Although complications are extremely rare, salivary gland FNA can lead to hemorrhage, facial nerve injury, and cellulitis at the needle puncture site. Some studies suggest that FNA can cause infarction or metaplastic transformation of benign Warthin's tumors. We review our recent experience with FNA of the parotid gland, focusing on possible complications and pitfalls. STUDY DESIGN AND SETTING: The medical records of all patients who underwent FNA of the parotid gland from 2000 to 2002 in the Department of Otolaryngology-Head and Neck Surgery of a major tertiary-care referral center were reviewed. Cytological results were compared to the histological diagnosis and complications were recorded. RESULTS: Of the 256 lesions aspirated, 99 patients (39%), were cytologically diagnosed as benign tumors, including 31 (12%) Warthin's tumors, of which 16/17 resected and confirmed histologically. Five patients with Warthin's tumor had post-FNA parotitis and were treated accordingly. CONCLUSIONS: The combination of cystic spaces surrounded by oncocytic cells and a poor blood supply makes the tumor susceptible to infarction and inflammation. Our findings indicate that FNA is a strong and reliable tool in the investigation of the salivary glands. Nevertheless, when Warthin's tumor is clinically suspected on the basis of its location (tail of the parotid gland), cystic texture, patient sex (male) and age, one should consider parotitis as a possible complication. EBM rating: C-4.
