Juvenile Nasopharyngeal Angiofibroma with Intracranial Extension

Abstract

Objective. To provide a critical evaluation of the historical evolution of the surgical treatment of juvenile nasopharyngeal angiofibroma (JNA) with intracranial extension. Study Design. Case series with chart review. Setting. Skull base multidisciplinary group at the Instituto de Neurologia de Curitiba, Brazil. Subjects and Methods. From 1988 to 2000, the multidisciplinary skull base group surgically treated 67 adolescent boys with JNA, 20 of whom presented with intracranial extension. All patients presented involvement of the cavernous sinus, and 5 of them spread into the orbit. Before 2008, the authors combined microscopic-endoscopic techniques. After this period, the surgical approach used was facial degloving, associated with purely endoscopic technique patients. Results. Total tumor removal was achieved in 17 cases in the first surgery. In this series, the intracranial extension was extradural in all cases. There was only 1 case of cerebrospinal fluid leakage, which was promptly identified and treated. There was no mortality or permanent morbidity. Conclusion. Radical removal of large JNA may be difficult because of its extreme vascularity and extension to the cavernous sinus, orbit, middle and anterior fossa. Nevertheless, most of JNA with intracranial extension can be resected in the first operation with minimal morbidity through a facial degloving and further combination of expanded endoscopic endonasal approaches.
