CONCLUSIONS: We identified smoking as a significant risk factor for multilocular Warthin tumor development. Therefore, we recommend taking history of smoking into account when making the decisions for surgical strategy. OBJECTIVES: Warthin tumor is a common benign neoplasm of the parotid gland. Risk factors for multilocular development have not been defined. PATIENTS AND METHODS: A total of 185 consecutive patients treated for Warthin tumor were included. Charts were reviewed for symptoms, risk factors, and diagnostic and surgical procedures. Patients were followed for facial function and recurrence. Risk factors were evaluated. RESULTS: Overall, in 203 parotid operations, a lateral parotidectomy (77%) was performed in most cases; 94% were primary surgery and 6% were revision surgery. In 89% of patients swelling was the only symptom. Bilateral Warthin tumor was seen in 17% of patients. Of these cases synchronous and metachronous bilateral tumors were observed in 61% and 39%, respectively. The median time period for second contralateral tumor development was 7 years. Postoperative transient facial dysfunction was observed in 31%, which recovered within 3 months in all cases. Evaluation of risk factors revealed that 89% of the subjects were smokers and 66% were heavy smokers. The risk for bilateral Warthin tumors correlated significantly with the amount of nicotine intake (p=0.003).
