​Nuances of Technique for Transcondylar Osteotomy and Resection of an Encasing Foramen Magnum Meningioma

General Considerations

The lateral suboccipital or far-lateral approach and its variant, the transcondylar approach, have been developed to expose pathologies at the ventral and ventrolateral craniovertebral junction. This region includes the space anterior to the brainstem and the spinal cord, extending from the jugular bulb to the upper cervical spine.

This ventral region is difficult to reach microsurgically, and modifications of the lateral suboccipital pathway require varying degrees of bony resection so that the pathology can be reached without retraction on the medulla oblongata and upper spinal cord. Anterior route...
