Abstract

To provide the wide and satisfactory surgical field is essential requirement for en-bloc resection of nasopharyngeal angiofibroma invading central skull base. The new design of the surgical approach to the skull base lesions was developed and described the details of this technique and its usefullness. We compared the usefullness of naso-maxillary approach to that of infratemporal fossa approach in cases of angiofibroma invading skull base. Our experience indicates that the naso-maxillary swing approach is better than lateral approach for the large nasopharyngeal angiofibroma. A new approach. naso-maxillary swing approach. is described.
