Endoscopic endonasal approach for odontoidectomy

Contributors: M. Nathan Nair and Timothy Deklotz

For patients with basilar invagination, an odontoidectomy may be necessary to decompress the brainstem, before further correction and stabilization of the craniocervical junction can be achieved. The open-mouth odontoidectomy procedure is associated with significant moribdity, and the endoscopic endonasal approach may be a better option. In this video, we provide a step-by-step demonstration of the endoscpic endonasal approach for odontoidectomy.
