Resection of nasopharyngeal angiofibroma with extranasal and extrapharyngeal involvement.

The authors report their own experiences with the diagnosis and therapy of 7 cases of nasopharyngeal angiofibroma with extranasal and extrapharyngeal involvement, thereby attempt to formulate the surgical approach for resection of huge nasopharyngeal angiofibroma with extensive involvement. The results suggested that appropriate surgical approach was of paramount importance for eliminating the tumor and may effectively reduce traumatic injury during the operation. Elective embolization of the vessels feeding the tumor could reduce bleeding and therefore increase the safety of the operation.
