Abstract
Juvenile nasopharyngeal angiofibroma (JNA) is a benign tumor of the nasal cavity that predominantly affects young boys. Surgical removal remains the gold standard for the management of this disease. Preoperative intra-arterial embolization (PIAE) is useful for reductions in intraoperative blood loss and surgical complications. In our series of 79 patients who underwent preoperative embolization from 1999 to 2020, demographics, procedural aspects, surgical management and follow-up outcome were analyzed. Embolization was performed in a similar fashion for all patients, with a superselective microcatheterization of external carotid artery (ECA) feeders and an injection of polyvinyl alcohol (PVA) particles, followed, in some cases, by the deployment of coils . Procedural success was reached in 100% of cases, with no complications such as bleeding or thromboembolic occlusion, and surgical intraoperative blood loss was significantly decreased. In conclusion, PIAE is a safe and effective technique in JNA treatment, minimizing intraoperative bleeding.

Summary
Juvenile nasopharyngeal angiofibroma (JNA) is a highly vascularized and histologically benign tumor of the nasal cavity and paranasal sinuses, with aggressive behavior and locally invasive growth patterns [1]. It comprises 0.05% of head and neck tumors and predominantly occurs in young boys, with a mean age of presentation of 15 years [2,3]. The best treatment to date remains surgical removal of the tumor [3]. Preoperative embolization is used for virtually all cases of JNA, resulting in reduction in intraoperative bleeding, J.
