=====James K. Liu===== In a operative [[video]] manuscript, [[James K. Liu]] from the Departments of Neurological Surgery and Otolaryngology-Head and Neck Surgery, Center for Skull Base and Pituitary Surgery, Neurological Institute of [[New Jersey]], demonstrates an illustrative step-by-step technique for microsurgical resection of a thoracic intramedullary [[spinal cord ependymoma]] (T-3 to T-5) associated with an extensive cervicothoracic [[syrinx]]. The application of a handheld non-contact [[CO2 laser]] for performing the midline [[myelotomy]] is also highlighted. The [[operative technique]] and surgical nuances, including the surgical approach, intradural tumor removal, and closure, are illustrated in this video [[atlas]].
