Nasopharyngeal angiofibroma

In the juvenile nasopharyngeal fibroma is a histologically benign tumor originating from the pharyngeal roof. It usually occurs in male adolescents from the age of 10. Histologically, there is an angiofibroma, so a highly vascular fibroma. It grows locally displacing and destructively in the paranasal sinuses, the orbit, the pterygopalatine fossa and nose. For this reason, its growth behavior should be regarded as malignant.

Symptoms

It comes to nasal obstruction. It can also cause purulent rhinitis, tubal dysfunction and thus to a conductive hearing. Patients may also complain of headaches, and because of well-perfused tumor leads to nosebleeds because the thin-walled vessels can tear quickly.

Diagnosis

The diagnosis is made through the posterior rhinoscopy. Also imaging processes such as magnetic resonance imaging and in cases of suspected bone destruction computed for use. Angiography with embolization of the tumor may be performed to reduce the risk of bleeding. Because of the high risk of bleeding of the tumor no biopsy of the tumor is removed.

Treatment and prognosis

In large fibroids, surgery is indicated. Above should, if possible, embolization of the tumor are implemented to reduce the risk of bleeding. The irradiation should be carried out in inoperable tumors. The juvenile nasopharyngeal fibroma may regress spontaneously after puberty.
