Abstract

Background: With advances in endoscopic surgical techniques, endonasal decompression of the medial orbit and optic canal for compressive optic neuropathies is occurring more frequently. In the past, there has been debate in the literature regarding the capacity of this procedure to adequately decompress the optic nerve, primarily due to its inability to unroof the optic canal or resect the intracanalicular portions of skull base tumors. Our objective in the present study is to review the outcomes, in terms of preservation and restoration of visual function, of patients who have undergone endoscopic endonasal optic nerve decompression, and to compare those outcomes to patients undergoing open cranial procedures.
