dc.description.abstractBACKGROUND AND PURPOSE: Surgical excision of an affected sublingual gland for treatment of a ranula can carry a potential of a nerve damage or postoperative complications. However, there have been little studies about effective minimally invasive therapeutic method, yet. Our aim was to evaluate the efficacy and safety of ethanol ablation of ranulas and the clinicoradiologic factors that can predict outcome. MATERIALS AND METHODS: This retrospective study evaluated 23 patients with ranulas treated by percutaneous ethanol ablation. Treatment outcome was assessed in 20 patients followed for at least 6 months. The duration of symptoms before ethanol ablation, pretreatment volume, and parapharyngeal extension on sonography and/or CT were correlated with the outcome. The Mann-Whitney U test and Fisher exact test were used for comparison of the factors according to the outcome. RESULTS: The study evaluated 14 males and 9 females with a median age of 26 years (range, 3-41 years). Among 20 patients who were followed for at least 6 months (median, 20 months; range, 6-73 months), 9 patients (45%) demonstrated complete disappearance of the ranulas and 11 (55%) showed an incomplete response. When the patients were divided according to the duration of symptoms before ethanol ablation, the complete response rate was significantly higher in patients with 12 months of symptoms (73%, 8/11) than that in others (11%, 1/9) (P = .010). Pretreatment volume and parapharyngeal extension were not significantly different between the 2 groups. CONCLUSIONS: Ethanol ablation is a safe and noninvasive treatment technique for ranulas with a significantly better outcome in patients with 12 months of symptoms. Therefore, it could be considered an alternative nonsurgical approach for ranulas with recent onset of symptoms.-
