Abstract

Abstract: Objective: This study compared the efficacy of microwave ablation and silver nitrate cautery as treatments for idiopathic recurrent anterior epistaxis in adults. Methods: A case series with chart review was conducted. Adults with recurrent anterior epistaxis intra-operatively treated via microwave ablation or silver nitrate chemical cautery of the anterior nasal septum were enrolled. The primary outcomes were the proportion of patients in each group for whom bleeding ceased within 24 hours of treatment, and the time to successful haemostasis. The secondary outcomes were re-bleeding rates at 1 and 12 weeks and 6 months, and complications. Results: The haemostasis success rate within 24 hours' treatment of convex lesions was significantly higher in the microwave ablation group than in the cautery-only group. Of patients with convex lesions, the recurrence rate to six months was significantly higher in the cautery group than in the microwave ablation group, but this was not the case for those with flat lesions. Conclusion: Microwave ablation afforded rapid and simple haemostasis for adults with recurrent anterior epistaxis in an out-patient setting. Microwave ablation had significant advantages compared to silver nitrate cautery when used to treat epistaxis in patients with convex lesions.
