Endoscopic endonasal approach for resection of pediatric chordoma with brainstem invasion. Neurosurgical focus: Video Abhinav, K., Hong, D., Yan, C. H., Hwang, P., Fernandez-Miranda, J. C. 2019; 1 (2): V20

Abstract

A 14-year-old boy had undergone an orbitozygomatic craniotomy for a pontine lesion. There was growth on surveillance imaging with involvement of posterior clinoids, clivus, and left pons suggestive of chordoma (Fernandez-Miranda et al., 2014b). An endoscopic endonasal approach was undertaken involving full upper and midclival exposure including bilateral posterior clinoidectomy (Fernandez-Miranda et al., 2014a; Truong et al., 2019a, 2019b). The internal carotid artery was skeletonized to maximize exposure and facilitate safe resection. The tumor was removed from between the dural layers of the midclivus while preserving the interdural abducens nerve (Barges-Coll et al., 2010). The brainstem component was resected while preserving the pontine perforators. Postoperative diagnosis was chordoma with MRI demonstrating complete resection. The patient was intact postoperatively.
