Juvenile nasopharyngeal angiofibroma (JNA) is a benign though locally aggressive tumour primarily affecting adolescent males. Although a benign tumor, lesions may be locally aggressive and erode into the surrounding osseous and soft tissue structures.It is highly vascular tumor. Thus it poses a significant challenge during its surgical resection as it has a high risk of uncontrollable hemorrhage.
Juvenile nasopharyngeal angiofibromas pose a significant bleeding risk for the surgeon due to their highly vascular nature.
Pre-operative angiographic embolization of the major feeding vessels to the tumor has become a necessary tool in the surgical treatment of these lesions.
