Fig. 1 Upper row: initial MRI displaying basilar invagination with lower brainstem compression; MRI after suboccipital decompression in another institution showing secondary syringomyelia; and MRI after odontoidectomy with brainstem decompression and craniocervical stabilization. Lower row: bone window CT scan before and after odontoidectomy. MRI, magnetic resonance imaging.

Fig. 2 Endoscopic intraoperative control demonstrating transoral epipharyngeal approach with soft palatal preservation and decompression of the brainstem after odontoidectomy.
