Juvenile nasopharyngeal angiofibroma.

Juvenile nasopharyngeal angiofibromas (JNAs) are rare, benign, highly vascular, locally aggressive tumors that primarily affect male adolescents. Historical treatment of these neoplasms has been primarily surgical. In the past decade, endoscopic resection of JNAs has become a viable and promising surgical treatment option. Endoscopic resection has many advantages over traditional open techniques, including better cosmesis, decreased blood loss, shortened hospital stays, and equivalent or improved recurrence rates. Emerging endoscopic technology continues to push the boundaries of resection of skull base tumors and will no doubt become the surgical treatment of choice for most JNAs in the near future.
