  • Title: Relative risk factors in the treatment of juvenile nasopharyngeal angiofibroma.
    Author: Cummings BJ.
    Journal: Head Neck Surg; 1980; 3(1):21-6. PubMed ID: 6250995.
    Abstract:
    The potentially fatal complications associated with surgery and radiation therapy in the management of juvenile nasopharyngeal angiofibroma (JNA) are analyzed. Quantitative risk factors established from review of the literature suggest a risk of potentially fatal complications of 1 in 3,000 from general anesthesia, 1 in 1,600 from arteriography, 1 in 160 from blood transfusion, and 1 in 500 from the surgical procedure itself. The total of these risks is comparable to the 1% lifetime risk of developing a radiation-induced tumor after radiation therapy. The time pattern of these complications differs in that fatal radiation-induced complications are delayed, whereas the risks associated with surgery, general anesthesia, and blood transfusion are more immediate. However, it is suggested that treatment-related risks of fatal complications are of a similar order of magnitude for surgery and for radiation therapy in the management of JNA.
