OBJECTIVE: To evaluate the efficacy and safety of ethanol ablation in the treatment of benign head and neck cystic lesions.
METHODS: A total of 25 patients who received ethanol ablation (EA) of head and neck cystic lesions by an otolaryngologist at a single institution between October 2017 and October 2020 were identified. Patient demographics, clinical characteristics, treatment details, and treatment outcomes at follow up visits were obtained by retrospective review of electronic medical records.
RESULTS: 25 patients who underwent ethanol ablation of head and neck cystic lesions were included, with a mean age of 49.1 years old (Interquartile range (IQR),32.5-65.5 years) and 12 males (47.0%). The most common cysts treated with EA were thyroglossal duct cysts (n = 8, 32.0%) and lymphoepithelial parotid cysts (n = 7, 28.0%). The mean volume prior to treatment was 10.57 mL (IQR, 1.58-8.81 mL). Mean volume following EA was 1.30 mL (range, 0.10-0.97 mL) with 74.40% cyst reduction by volume (IQR, 48.56-96.29%) (p = 0.002). The mean time to the last follow-up was 5 months (range, 3-6 months). One patient received surgery despite treatment success to obtain a definitive diagnosis of the mass. No other patients received further surgical management. The treatment success of EA, as defined by >70% volume reduction or the resolution of symptoms, was 92.0%. All patients were satisfied with the outcome and had no reported complications.
CONCLUSION: EA is an effective and safe alternative to surgery for the treatment of head and neck cystic lesions that can be performed in an outpatient setting by an otolaryngologist.
