Two types of lateral extension in juvenile nasopharyngeal angiofibroma: The final diagnosis is achieved by histopathologic examination of tissue sections either on incisional or excisional biopsy.
The condition is most commonly treated by surgical excision and the surgical approach is chosen according to the disease stage.
