Nasopharyngeal angiofibroma: Our experience and literature review

Another recent study of Schlauder et al suggests that the enzyme aromatase is responsible for local conversion of androgens to estrogens, which in turn relates to the role of estrogen receptors in tumor growth Open in a separate angiofibbroma. We also found that patients who underwent clamping of the external carotid artery and embolization showed less intraoperative bleeding than patients who underwent embolization alone. Follow-up after surgery to detect recurrence.

The 18 patients who underwent embolization did so h prior to surgery Figure 5.

All patients were treated surgically, including 17 who underwent endoscopic surgery. The NAJ is rare, accounting for 0.

Other names have been used as a nasopharyngeal fibroma, fibroma of the adolescent and bleeding fibroangioma 1. Because these tumors are benign, metastasis to distal sites does not occur. Intraoperative control of bleeding during the resection of nasopharyngeal angiofibromas can be achieved successfully by temporary clamping of the external carotid arteries in the neck Surgical methods in all patients were based on Fisch classifications.

None of our patients experienced complications due to embolization. Seventeen patients required clamping of the external nasofaringo and tumor embolization. From your point of origin then begins its growth beneath the mucosa, extending initially to the posterior nasal cavity and nasopharynx 4. Intraoperative control of bleeding during the resection of nasopharyngeal angiofibromas can be achieved successfully by temporary clamping of the external carotid nssofaringeo in the neck Endoscopic Surgery for Juvenile Angiofibroma: Article accepted in October 7, Numerous growth factors seem to be implicated in the pathogenesis of tumor.
