Optic Canal Decompression With Dural Sheath Release; A Combined Orbito-Cranial Approach To Preserving Sight From Tumours Invading The Optic Canal
2012
Purpose: The purpose of this case series is to describe an orbito-cranial surgical approach for the management of optic nerve compression secondary to tumours extending into the optic canal.Method: We present a retrospective, observational case series of 4 patients who underwent surgery aimed at improving or stabilising vision for tumours invading the optic canal. In all cases tumours were not amenable to complete resection due to their intrinsic relation to important structures including: the internal carotid artery, cavernous sinus, optic and oculomotor nerves. All patients underwent combined orbito-cranial surgery consisting of craniotomy, debulking of the tumour, transcaruncular orbital and optic canal decompression with release of the dural sheath overlying the optic nerve via the craniotomy approach. Visual acuity was the primary outcome measure.Results: Four patients, aged 42, 44, 61 and 78 years, three with spheno-orbital meningioma and one with cerebral sino-nasal adenocarcinoma were included in ...
