Transorbital neuroendoscopic approach for recurrent sinonasal inverted papilloma.

Abstract

This surgical video demonstrates the case of a 38-year-old male with recurrent inverted papilloma involving the lamina papyracea and frontal sinus outflow tract. The frontal sinus was diminutive on the side of the tumor, and as such a combined endoscopic endonasal with endoscopic transorbital via transcaruncular route was advised for resection of the anterolateral tumor and contralateral margin. After endonasal resection, a transorbital approach was utilized to traverse the lamina papyracea from lateral to medial and resect tumor along the ethmoid roof and posterior table of the frontal sinus.
