Occipitocervical fusion with relief of odontoid invagination: Atlantoaxial distraction method using cylindrical titanium cage for basilar invagination - Case report. Commentary

摘要

Optic radiation (OR) stimulation during awake resection of brain tumors has been repeatedly reported; however, the data are still sparse [2, 8, 10, 21]. In all cases, visual function monitoring was performed in patients with open eyes which were looking at a picture. We report a new modification of the standard method, OR stimulation in patient with closed and covered eyes. According to our first experience, this methodology may be in some cases a potentially more sensitive form of neuromonitoring than the OR stimulation in patients with open eyes.
