Optic Nerve Decompression through a Supraorbital Approach

Endoscopic Optic Nerve Decompression Through Supraorbital Keyhole Extradural Approach: A Cadaveric Study.

AIM Many approaches for optic nerve decompression have their own advantages and disadvantages. The aim of this study was to perform endoscopic decompression of optic nerve through the supraorbital keyhole and evaluate its feasibility. MATERIAL AND METHODS Ten adult cadaveric heads were studied using 4-mm, 0- and 30-degree rigid endoscopes to perform the optic nerve decompression through the s...

Optic nerve ischemia: optic nerve sheath decompression alone or with optic nerve decompression.

Endoscopic orbital and optic nerve decompression.

The endoscopic transnasal approach is well suited for decompression of both the orbit and optic canal. High-resolution nasal endoscopes provide excellent visualization for bone removal along the orbital apex and skull base. Endoscopic orbital decompression has proved to be safe and effective for the treatment of patients with Graves' orbitopathy; however, the indications and outcomes for endosc...

The efficacy of optic nerve sheath decompression for anterior ischemic optic neuropathy and other optic neuropathies.

First proposed by De Wecker! in 1872 as a treatment for neuroretinitis, optic nerve sheath decompression (or fenestration) is an operation that has caused much controversy. This surgical therapy was not seriously considered until Davidson" and Smith, Hoyt, and Newton" reintroduced it in 1969 as an alternative therapy for chronic disk edema. Over the next 19 years, however, only about 60 cases o...

Teaching NeuroImages: microvascular decompression of the optic nerve.

Vascular compression is a known cause of cranial nerve dysfunction in a variety of disease states including trigeminal neuralgia, hemifacial spasm, and hypoglossal neuralgia.(1,2.)
