Endoscopic optic nerve decompression through supraorbital keyhole extradural approach: a cadaveric study

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...

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...

Supraorbital keyhole approach for anterior circulation aneurysms.

AIM Supraorbital keyhole approach provides access to the major part of the anterior circulation aneurysms. Herein, our surgical experience of supraorbital keyhole approach and its some modification have been proposed. MATERIAL AND METHODS Out of a series of 76 patients harboring 80 aneurysms operated on via a supraorbital keyhole approach with a superciliar or front wrinkle skin incision, the...

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

Modified Supraorbital Keyhole Approach to Anterior Circulation Aneurysms.

OBJECTIVE To select a surgical approach for aneurysm clipping by comparing 2 approaches. MATERIALS AND METHODS 204 patients diagnosed with subarachnoid hemorrhage treated by the same neurosurgeon at a single institution from November 2011 to October 2013, 109 underwent surgical clipping. Among these, 40 patients with Hunt and Hess or Fisher grades 2 or lower were selected. Patients were assig...
