Endoscopic Ressection of Juvenile Angiofibroma: All patients were male, and all had symptoms of progressive nasal obstruction and recurrent epistaxis. The combination of different accesses to the tumor can be required 9. Direct intratumoral embolization of juvenile angiofibroma. Nasoofaringeo tumors occur almost exclusively in male adolescents and account for 0. Tumor volume was not associated with bleeding in patients nasofarlngeo and without clamping.

These tests have led to the formulations of multiple classification methods, including the FischR adkowskiA ndrewsB remerand A ntonelli methods 1 4 5 7 8.

Angiofibroma nasofaríngeo juvenil

However, these tumors are highly vascularized and grow rapidly. All patients were treated surgically, including 17 who underwent endoscopic surgery.

The major concern regarding the choice of pathway is the rate of tumor recurrence, which has generated much discussion. Some surgeons, however, nasofafingeo not routinely perform embolization preoperatively, finding that embolization is justified only in larger tumors The average age at diagnosis was Non-surgical treatments are available, including the use of hormones estrogen, testosteroneradiation therapy, chemotherapy, and recently, embolization; aangiofibroma, surgery is considered the treatment of choice, with the route depending on the stage of the tumor and the overall condition of the patient 11 12 The mean operation time was min, and the mean bleeding volume was mL.

Nasopharyngeal angiofibroma

Moreover, the mean blood loss in these patients was mL. Its blood supply nasofadingeo done by the internal nnasofaringeo artery, may also be branches of the ipsilateral internal carotid artery 4,6.

Endoscopic approach is an excellent tool in primary and recurrent JNA, it allows visualisation and precise removal of the lesion. This relatively low blood loss may be due to the use of surgical endoscopy, providing better control of bleeding than open surgery, with or without endoscopy.

The combination of different accesses to the tumor can be required 9. The other 17 patients underwent endoscopic surgery alone.

Pathogenisis of Angiofibrom Nasopharyngeal Fibroma A new concept. Article accepted in October 7, Endoscopic Laser-assisted excision of juvenile nasopharyngeal angiofibromas.

Classification of Fisch Type I: The most significant risk is blindness, for patients with occlusion of the ophthalmic or middle cerebral artery through the collateral circulation.

Nasal endoscopy, alone or combined with open techniques, was safe for the resection of angiofibromas at different stages, with low morbidity and high efficacy, as shown by complete tumor removal and low recurrence rates.

CT of the paranasal sinuses. HUANG et al 25 show that the technique with two surgeons via the transseptal later shows less morbidity and lower rate of recurrence after resection of the tumor proper.

Juvenile nasopharyngeal angiofibroma NAJ is a tumor with vascular component, slow growing, benign but very aggressive because of its local invasiveness. Anigofibroma carotid clamping has been shown to assist in hemostasis of the tumor.

Endoscopic surgery alone or with other conventional techniques was safe for the treatment of angiofibromas of different stages.

Nasopharyngeal angiofibroma – Wikipedia

For example, a retrospective study of 15 patients found tumor recurrence in 1 patient 6. Juvenile nasopharyngeal angiofibroma originates in the sphenopalatine forame, causing epistaxes and nasal obstruction. 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 The genetic alterations observed more often involve sex chromosomes. From your point of origin then begins its growth beneath the mucosa, extending initially to the posterior nasal cavity and nasopharynx 4.

Current Management of juvenile nasopharyngeal angiofibroma: Embolization of a year-old patient with a Fisch IIIa juvenile nasopharyngeal angiofibroma. So you have access to the wide portion of the maxillary sinus, greatly facilitating the resection of tumors with lateral extension to the infratemporal fossa.

In this study, we have described our experience in treating 20 patients with nasopharyngeal angiofibromas in the Department of Otorhinolaryngology. Tratado de otorrinolaringologia 2 Ed.

They may extend towards the nasopharynx, which includes the maxillary, ethmoid, and sphenoid sinuses. The tumor invades the nasal sinuses or the pterygomaxillary fossa with bone destruction.
