Juvenile nasal angiofibroma (JNA) is a hypervascularised, benign, but locally aggressive tumour that grows in the posterior, upper part of the nasal cavity and invades surrounding anatomical structures. The treatment of choice is surgical removal, but complete resection of the tumour can be hampered because of profuse perioperative bleeding. Preoperative embolisation of the tumour has been proposed as an effective method for prevention of perioperative bleeding, thereby shortening of the time of the operation. In this report of five cases, we describe successful preoperative devascularisation of the tumour by applying a modified method of direct intratumoural injection of the liquid embolic agent Onyx combined with protection of the internal carotid artery. The control of bleeding during the embolisation and occlusion of the maxillary or sphenopalatine artery was achieved by using a bi-luminal balloon catheter. Such use of the dual-lumen catheter in treatment of JNA has not been reported so far in the medical literature.
