The retropharyngeal approach is used to avoid the risks and limitations of transmucosal surgery. The standard Smith-Robinson approach does not allow complete exposure of the C3 body/disk in patients requiring instrumentation of C3 or in patients with

We present the unique case of a patient with a sequestered disk fragment posterior to the thecal sac producing symptoms of spinal stenosis with neurogenic claudication. The majority of sequestered disk fragments migrate in either a cranial or caudal
