The risk factors for residual juvenile nasopharyngeal angiofibroma and the usual residual sites

摘要

Objective: Juvenile nasopharyngeal angiofibroma (JNA) is non-metastasizing but potentially locally destructive tumor of the nasopharynx. It can destroy the skull base and invade into the cerebrum. Surgical management is the primary standard but residual disease is always a risk factor. We aimed to determine the risk factors for residual disease and usual sites for these residual tumors.
