“…3,20 The endoscopic endonasal approach is not only safe for medial orbital wall decompression in optic nerve injuries, but it also serves as a useful therapeutic tool during the management of more diffuse compressions as seen in sphenoorbital meningiomas. 5,7,10,11,13,18,21,22 This approach, however, is best suited for inferomedial dural-extradural pathologies, while the contralateral supraorbital keyhole approach better addresses intradural superomedial compressive lesions. In addition, if the lesion extends lateral to the anterior clinoid, it will not be amenable to resection through the endonasal route, while the contralateral keyhole approach will still be applicable.…”

OBJECTIVE The authors describe the supraorbital keyhole approach to the contralateral medial optic nerve and tract, both in a series of cadaveric dissections and in 2 patients. They also discuss the indications and contraindications for this procedure. METHODS In 3 cadaver heads, bilateral supraorbital keyhole minicraniotomies were performed to expose the ipsilateral and contralateral optic nerves. The extent of exposure of the medial optic nerve was assessed. In 2 patients, a contralateral supraorbital keyhole approach was used to remove pathology of the contralateral medial optic nerve and tract. RESULTS The supraorbital keyhole craniotomy provided better exposure of the contralateral superomedial nerve than it did of the same portion of the ipsilateral nerve. In both patients gross-total resections of the pathology was achieved. CONCLUSIONS The authors demonstrate the suitability of the contralateral supraorbital keyhole approach for lesions involving the superomedial optic nerve.

PurposeTraumatic optic neuropathy (TON) is a serious complication of head trauma with the incidence rate of 0.5%–5%. The aim of this study was to investigate the therapeutic efficacy of endoscopic decompression of the optic canal for optic nerve injuries.MethodsIn this study, 11 patients treated in our hospital from January 2009 to January 2015 with the visual loss resulting from TON were retrospectively reviewed for preoperative vision, visual evoked potential (VEP) scan, surgical approach, postoperative visual acuity, complications, and follow-up results.ResultsAll these patients received endoscopic decompression of the optic canal. At the 3-month follow-up, the visual acuity improvement rate of the 11 patients was 45.5%. The vision acuity of 2 cases improved from hand movement to 0.08 and 0.3 after operation. Another patient's vision acuity returned to 0.05 compared to light sensation preoperatively. Two cases had finger counting before surgery but they had a vision acuity of 0.4 and light sensation respectively after surgery. However, the other 6 cases' vision did not improve after surgery.ConclusionEndoscopic decompression of the optic canal is an effective way to cure TON. VEP could be used as an important reference for preoperative and prognosis evaluation. Operative time after trauma is only a relative condition that may affect the therapeutic effect of optic canal decompression. Poor results of this procedure may be related to the severity of the optic nerve injury.

Traumatic optic neuropathy (TON) is the affectation of the visual function, secondary to a damage caused by a direct or indirect traumatic mechanism over the optic nerve. It occurs in approximately 0.5 to 5% of closed head injuries, and in 2.5% of patients with maxillofacial trauma and mid-face fractures. The types of TON are direct, anterior indirect, posterior indirect, and chiasmal. This work aims to offer an updating in traumatic optic neuropathy. We made a search in international data bases such as PubMed, ClinicalTrial, Ebsco, Hinari and so on, and found 32 articles which were used in this review article. We used the following keywords: traumatic optic neuropathy, optic nerve, trauma, visual loss, visual disease. 70% of the articles correspond to the last five years. This review was redacted using Microsoft Office Word 2016 in a laptop Asus with Window 10 system. We made a compilation with diverse therapeutic options based principally in axonal regeneration developed by researchers during the last decade. The present review article provides an updating regarding potential strategies for axonal regeneration and optic nerve repair, focusing on the researches of many investigators around the world. Nowadays, therapeutic options have advanced in many fields, but still more researches must be done to find a definitive solution for traumatic optic neuropathy in a near future.
