The first description of an endoscopic resection was published in Ideally, the time between the completion of embolization and the endoscopic procedure should be as small as possible, approximately h The remaining 17 patients, regardless of the tumor classification, underwent embolization and clamping of the external carotid arteries due to better juevnil of bleeding during surgery.
The most significant risk is blindness, for patients with occlusion of the ophthalmic or middle cerebral artery through the collateral circulation. Introduction Nasopharyngeal angiofibroma is a histologically and biologically benign tumor with aggressive behavior due to its location and associated symptoms including significant epistaxis and nasal obstruction 1 2 3 4 5.

Of our 20 patients, only 2 underwent surgery without embolization, with these 2 showing significantly greater intraoperative bleeding than the 18 patients who underwent embolization. Service chief medical residency in Otorhinolaryngology, Universidade Federal de Sergipe.
Retrospective, descriptive study conducted after approval from the Ethics Committee of the Federal University of Sergipe protocol The classic triad of epistaxis, unilateral nasal obstruction, and a mass in the nasopharynx suggests a diagnosis of nasopharyngeal angiofibroma and is supplemented by imaging 11 12 13 14 Nasopharyngeal angiofibroma is a histologically and biologically benign tumor with aggressive behavior due to its location and associated symptoms including significant epistaxis and nasal obstruction 1 2 3 4 5.
The third patient with a Fisch I tumor underwent surgery with embolization, but without clamping of the external carotid arteries.
Biopsy should be avoided as to avoid extensive bleeding since angiifibroma tumor is composed of blood vessels without a muscular coat.

Moreover, the mean blood loss in these patients was mL. To minimize complications, surgery should be performed at centers with extensive experience. Juvenile nasopharyngeal angiofibroma originates in the sphenopalatine forame, causing epistaxes and nasal obstruction. Mortality is not associated with nasopharyngeal angiofibroma. Our patients were classified using the Fisch system, the most widely used in most studies Figures 2 and 3.

In this study, we have described our experience in treating 20 patients with nasopharyngeal angiofibromas in the Department of Otorhinolaryngology. Of our 20 patients, only 2 underwent surgery without embolization, with these 2 showing significantly greater intraoperative bleeding than the 18 patients who underwent embolization.
Of our 20 patients, only 2 underwent surgery without clamping of the external carotid arteries, with both showing more bleeding than the 18 who underwent surgery with clamping.
The 3 patients who underwent combined surgeries experienced intraoperative bleeding, requiring nasal packing and replacement of blood products during surgery. Views Read Edit View history. Surgery of cranial base tumors.
