Endoscopic endonasal resection of sinonasal/anterior skull base malignancy (Kadish C esthesioneuroblastoma).

Background: The surgical management of anterior skull base malignancies requires the full complement of open and endoscopic skull base approaches. Due to the evolution of endoscopic techniques, endoscopic approaches are now being employed for complex skull base tumors.

Methods: We present our technique for endoscopic management for an advanced (T4) anterior skull base malignancy that provides a systematic approach to resection, margin assessment, and reconstruction.

Conclusions: Our surgical strategy provides a systematic approach by which an oncologic resection can be performed within the context of a spectrum of surgical strategies necessary to manage skull base malignancies.
