Case: We report 3 patients with classic trigeminal neuropathy (TN) findings, which were due to compressive cervical radiculopathy, and provide a brief anatomic explanation for this association. In each case, left-sided disk herniation between the C5 and C7 levels caused TN and classic (dermatome appropriate) cervical radicular findings, all of which resolved with anterior cervical decompression and fusion (ACDF).
Conclusions: To our knowledge, this is the first report of TN caused by radicular compression in the caudal subaxial (C5-C7) cervical spine, which resolved after ACDF.
