Multimodality approach for advanced-stage juvenile nasopharyngeal angiofibromas.

BACKGROUND: Juvenile nasopharyngeal angiofibromas (JNAs) with significant skull base involvement and intracranial extension are challenging tumors. We evaluated our experience in the treatment of extensive JNAs through resection followed by radiosurgery.

METHODS: From 1999 to 2007, 10 advanced JNAs (Andrews grade IV) were treated by primary surgical resection followed by gamma knife radiosurgery of residual tumor. Tumor control and treatment morbidity were evaluated.

RESULTS: Six months after radiosurgery and annually thereafter, an imaging study was done that revealed decrement in tumor size in 3 patients and no change in 7 patients, after a 3-year minimum follow-up. Clinically, patients are asymptomatic.

CONCLUSION: An efficient strategy in the management of extensive JNAs is the use of a multimodality approach, in which surgical resection is followed by the treatment with radiosurgery in critical locations. These therapeutic schemes are safe and offer long-term tumor control.
