BACKGROUND: Anteriorly located lesions at the craniocervical junction (CCJ) require careful surgical planning to avoid neuraxis retraction. Several different routes have been described in the search for the most appropriate yet least invasive approach. However, most of these far-lateral posterior approaches are specifically tailored for non-osseous @entity5 or @entity3580 with cephalad extension. We introduce an approach that allows for better access to laterally extending @entity5 originating from the second cervical vertebra. Using this approach, the lesion is manipulated from a strictly lateral direction parallel to a plane through the articular pillar of the CCJ and the odontoid process, and the C1- and C2-laminae are spared for posterior fixation. METHOD: The application of this approach is demonstrated in detail by an illustrative case of a @entity3580 originating from C2 that presented with intradural mass effect, considerable @entity79 , far-lateral extension to the right, and vertebral artery involvement. FINDINGS: The described approach gave ample access for total @entity5 resection. It allowed for safe control and @entity5525 , spinal cord decompression, C2-corpectomy across the midline, and anterolateral bone reconstruction. No C1- or C2-hemilaminectomy was needed, and these bone elements could be used for posterior fixation (the @entity1 presented in this study was referred to our institution after posterior fixation from the occiput to C3 had already been performed elsewhere). No intra-operative or @entity260 occurred. At the 6-month follow-up, the @entity1 was fully ambulatory with no @entity51 . INTERPRETATION: The described lateral transfacetal route is the method of choice for operating on laterally extending @entity5 originating from the second cervical vertebra.
