Abstract: Background: Juvenile nasopharyngeal angiofibroma (JNA) is a rare tumor that mainly affects young boys. Its intervention may be complex due to its high vascularity, location, and extension. Preoperative embolization is used to prevent intrasurgical and postsurgical bleeding. Two main kinds of embolization are described in literature: intratumoral and transarterial, and numerous embolic materials are used. Case Presentation . We want to present a case of presurgical embolization of a stage IV JNA, performed using a single stop-flow balloon assisted technique with the balloon cuffed exclusively in the external carotid artery and using Onyx 18 as an embolic agent.<br />Conclusions: The embolization with an exclusive external carotid artery single stop-flow technique using Onyx 18 is a safe, effective, and a definitive approach.<br />Competing Interests: The authors declare that they have no conflicts of interest.<br /> (Copyright © 2023 Eliodoro Faiella et al.)
