Twenty patients with Parotid Warthin's tumor were recruited. RFA was done between September and December 2021 for all 20 patients using a CoATherm AK\u2010F200 machine with a disposable, 18G\u2009\u00d7\u20097\u2009mm radiofrequency electrode. Results and follow\u2010up statistics were compared with a historic sample of patients with parotid Warthin's tumor who underwent parotidectomy between 2019 and 2021 in the same center.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Nineteen patients were included in the analysis as 1 patient dropped out after 4 weeks of follow\u2010up. The mean age for the RFA group was 67 years old with most of them being male smokers. At a median of 45 weeks (44\u201047 weeks) postprocedure there was a 7.48\u2009mL (68.4%) volume reduction compared to baseline. Three patients had transient facial nerve (FN) paresis, 1 recovered within hours, and the other 2 by 12 weeks follow\u2010up. Three patients had great auricular nerve numbness; 1 patient had infected hematoma treated in an out\u2010patient manner. Compared to a historic cohort of parotidectomy patients for Warthin's tumor, there was no significant difference in FN paresis and other minor complications between the 2 treatment modalities.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The current analysis suggests that USG RFA\u00a0of Warthin's Tumor is a safe alternative to parotidectomy with
